Multiplayer game based on eye tracking

Date: April 2017
Experiment conductor: Michal Baňas
Supervisor: Jozef Tvarožek
Short description: The aim of the project is to create a prototype of a software application, with which then the usability of this app will be tested using EyeTracker in our faculty’s user experience and interaction research centre. The app is a multiplayer game, that can be controlled using several ways (mouse, keyboard, gaze control). The EyeTracker device will monitor and record user’s gaze during the whole playtime and then the app will evaluate all the information to find out, what is more interesting and attractive to user and what part of the game does the player focus on the most. Whilst playing, the user can collect multiple bonuses, that can help or harm him or his opponent. Using this, we can assume, whether the user has more attacking style of the game or the defensive one. I would also like to explore different versions or levels of the game with different distribution of the elements to find out, which one is the most natural to the user.

Visual goal searching

Date: April 2017
Experiment conductor: Šimon Dekrét
Supervisor: Ing. Patrik Polatsek
Short description: Human’s brain receives every second great amount of information. Major part of the information comes from visual system. Such amount of bits would not be processed without previous filtering. The filter is provided with visual attention which is the main factor for being able to perceive effectively and in real time our surroundings. Our experiment will be focused on study of the visual attention. Bottom-up attention will be observed thanks to basic object photos. The top-down attention will be observed thanks to more complicated photos containing more objects. Goal of the observer will be to find the questioned object. Based on this results, we will be able to design new model for visual searching.

Determination of the eye-catching parts in graphical interfaces

Date: March 2017
Experiment conductor: Patrik Beka
Supervisor: Ing. Márius Šajgalík
Short description: The purpose of project is to design neural network, that is capable of predicting eye-catching parts of web pages, just from the screenshot. It is closer described (or it will be) in my bachelor thesis. Neural network requires lots of relevant data for training, the more the better. Proposed experiment is simply and not long. 30 web pages of different kind will be shown to the participants (each for 5 seconds). Their task will be to memorize layout and content, because people are used to just quickly “scan“ the web page, but if they should memorize something, they tend to focus on multiple features. Our purpose in this experiment is to gain the sequence of views with durations, alternatively generated heatmaps.

The impact of color on visual attention

Date: March 2017
Experiment conductor: Daniel Nechala
Supervisor: Ing. Patrik Polatsek
Short description: Our surroundings consists of a variety of visual stimuli, such as intensity, color, orientation and movement. The human brain is not capable of handling all the stimuli at once, so it helps visual attention with the decision on which parts of the scene should the spectator focus his vision and subject them to detailed analysis. The methods which aim to predict visual stimulus-driven attention create maps which are known as saliency maps. These maps have a wide range of applications, such as robotics, security systems, image and video processing, and in medicine.

Analysis of usability smells through the eye-tracking

Date:  January 2017
Experiment conductor: Martin Svrček
Supervisor:
prof. Ing. Mária Bieliková, PhD.
Short description:
Nowadays, usability or user experience is very popular field and especially in the context of web, there is a lot research papers in this area. Within this issue, the main purpose is to detect various anomalies of the design of these applications and web pages. These anomalies are also called usability smells. Such detection is currently performed manually by experts on usability, who reveal these anomalies by evaluating the user studies. The efforts of a number of studies in this field is to automate this process in some way. Similar methods will be able to detect different usability smells. Available methods and approaches used solely records of user activity in the form of clicks, scrolling or keyboard input. Our aim is to analyze a gaze of the users to determine the characteristics or metrics that can detect usability smells and improve the process of their identification. More specifically, we focused on websites. As a part of our work, we created a list of 52 usability smells based on available research in this area due to fact that we can not find similar list in such a complete form. In order to find the gaze characteristics, we performed user study with eye-tracking, where participants had to perform some simple tasks on specific web site. Participants were divided into two groups. First group worked with web page with usability smells and second group worked with the same web page but without usability smells. Then, we compared each gaze metric as the length and number of fixations between these two groups in order to identify gaze characteristics which can reveal usability smells.

Instruction usage during user studies

Date:  December 2016
Experiment conductor: Jozef Melicherčík, Erik Chodorčuk (FIIT)
Supervisor:
Ing. Patrik Hlaváč
Short description:
User testing enables identification of problems and defects of the product, and its goal is to find these mistakes and eliminate them to improve user experience. During the study it may leads to different situations and the participants can be affected by stress, confusion, they do not know how to solve the task, etc. The participant must be informed good, timely and effectively to successful user study. The main task of this experiment is to find a model of confusion. This model will be presented as data from the eye-tracker with which we will be able to identify participant’s state of confusion and then will be provided instructions automatically. The experiment consists of six tasks. The tasks are simple, and each of them includes a set of instructions. Then we observe the same period of time just before the user clicked for the instructions. Then we create a model of confusion, when person is confused and must use the instructions. If we find a correlation between the obtained model of confusion and stress, which causes the problem area in our test, the system will automatically be able to show the instructions for participants, which will have a positive impact on the successful completion of tests.

Development,testing and evaluation of mathematical educational software

Date:  December 2016
Experiment conductor: Alžbeta Bachroníková (FMFI)
Supervisor:
RNDr. Peter Borovanský, PhD.
Short description:
For my bachelor thesis I created an educational software, in which users can practice and verify their math skills using the Hejny method. The developed application was adjusted for a target group, consisting of students of elementary school. Despite the fact, that application was successful and it serves its purpose, we believe that some phenomena still can be improved and user experience can be better. We will test usability with eyetracking, because this technique can reveal facts and problems which experimenter cannot easily notice (or cannot notice at all). After analyzing and evaluation of collected data, we will design and develop new application, which will guarantees the best user experience possible.

Detection of problematic sections for users while working with visualization

Date:  November 2016
Experiment conductor: Adam Bacho
Supervisor:
Ing. Róbert Móro
Short description:
Today, people collect data from a vast number of different sources. Their goal is to analyze this data for specific purposes. One of the most common ways of visualizing data in the process of knowledge discovery are decision trees, which may in certain exploratory analysis tools support decision of users. Specifically, we want be able to detect problematic sections of individual users when working with decision trees. The main resource that will enter the process of problems detection will be data obtained by tracking users’ gaze. These provide us with a large number of metrics that can significantly affect the quality of problematic parts detection. Another metrics that we plan to deal with are the number and length of fixations, saccades and AOIS’s semantics as it will be important to find out where the users look mostly, or where problems arise. It will be interesting to include metrics of the outside (ambient) and central (focal) perception as well. All these data are then used for problems detection using random forests, since it is highly effective when used for different purposes.

What can an eye tracker tell us about filled out electronic questionnaire?

Date:  November 2016
Experiment conductor: Dávid Csomor
Supervisor:
Mgr. Alena Kovárová, PhD.
Short description:
Main motivation behind this project is to identify and analyze correlation between the certain user behavior and the and the answer he selects in the electronic questionnaire. We consider problematic elements, which may increase cognitive load of the subject and result in a certain behavior, in other words in a certain answer.
Electronic questionnaire consists of instructions, questions with answers and feedback questionnaire in which the subject answers questions which should verify our hypotheses and their correctness. Selecting and placing of all the items of the electronic questionnaire, in other words the use of a certain font, font size, placement of items, order of items and so on is not negligible concerning the way the subject fills out the electronic questionnaire and the correctness of the answer.
Our goal is to collect data, which will allow us to find and verify our hypotheses about the questions in the questionnaire, which may help the researchers identify problematic questions in electronic questionnaire.

User experience and emotions

Date:  November 2016
Experiment conductor: Elena Štefancová, Ondrej Kaščák
Supervisor:
Ing. Róbert Móro
Short description:
Nowadays during design and usability testing of user interfaces we are more concern about overall user experience, which also includes emotions of users. Reliable detection of emotions can help us to find out if user is stressed or frustrated and reveal bottlenecks of usability. Emotions can be detected from face expressions, EEG (electroencephalogram) or with GSR (galvanic skin response).

Analysis of Reading Difficulty in Web Environment

Date:  October 2016
Experiment conductor: Štrbák Martin
Supervisor: Ing. Marián Šimko, PhD.
Short description: This project aims to capture and analyze the gaze and cognitive activity of a human reader during reading text with errors of different character, which will be intentionally added to the text. Reading is the most common form of human-computer interaction, and expansion of e-learning underlines the need for easily understandible content. The current method of analysis is the use of eye-tracking device, by measuring reading speed, and re-reading of word or whole sentence. We will extend this methodologies to capture the gaze of reader around errors in the text. Aside of eye-tracking, electroencephalogram will be used to capture cognitive load of human reader. Results will be used in further research in the field of text reading analysis.

Automatic evaluating usability of applications with eye-tracking technique

Date:  October 2016
Experiment conductor: Kutlíková Lenka
Supervisor: Ing. Jakub Šimko, PhD.
Short description: During experiments and also in real life users often don’t read instructions. When they are doing experiments it can skew results and the experiment is discarded. The main goal of this experiment is to find if users read given instructions. It consists of four parts with different simple tasks. Before every part there are instructions. Tasks are well-known for people so they are able to do them also without reading them.. The first one is Brick Breaker game in which users should move the paddle horizontally to the left and to the right in order to hit the ball. The second one is non-verbal reasoning test with 10 tasks.  The third one is the crossword where users should mark only horizontal words. The last task for users is to play Snake where they should take 15 points and end the game. Results from this experiment can help researchers to identify biased results and achieve higher quality of them.

sUXess: Online usability testing tool

Date: Mai 2016
Experiment conductor: Cuprik Róbert, Dubec Peter, Gajdošík Patrik, Roba Roman, Sanyová Monika, Vrba Jakub, Žigo Tomáš
Supervisor: Ing. Róbert Móro
Short description: Nowadays online usability testing becomes more and more popular and it enables us to perform usability testing without need of specialized laboratories and feedback from users is collected thanks to recording of user’s activity and with use of different questionnaires. With use of online usability testing we are able to decrease expenses and also to involve more users in usability testing. However the main problem of online usability testing is missing detailed monitoring of users.

There is great potential in combination of classic and online UX testing. It is possible to obtain detailed data about user’s behaviour with use of eye tracking, which allows us to rapidly increase level of online UX testing. We have created platform for online UX testing, which allows users to test web pages in different stages of development cycle.

Date: April 2016
Experiment conductor: Peter Dubec
Supervisor: prof. Ing. Mária Bieliková PhD.
Short description: Nowadays usability testing of mobile applications with use of eye-tracking is realized as traditional usability testing. It is not possible to perform mobile usability testing on multiple participants simultaneously, therefore in most cases these tests are qualitative and not quantitative because we are able to collect only small amount of data. Our main goal is to make bulk testing of mobile applications possible by means of simulating mobile applications on PC and collecting data from PC.

Universal tool to asign badges in online communities

Date: April 2016
Experiment conductor: Martina Redajová
Supervisor: Ing. Ivan Srba
Short description:The application of gamification is becoming a widely used technique of an activity motivation not only in learning process in educational domains, but also in other domains with no such purpose. The main goal of various gamification mechanics is to motivate users to visit a system, be active in this system and to have another reason to come back regularly. There are many types of game elements used to achieved this, such as leaderboards, storytelling, achievements and application of levels or badges. Assigning badges is one of the most promising elements of gamification because it is rewarding users for their activity with no need of permanent focus on progress. It is proven that user’s ambition to earn a badge is provided by natural human desire of owning something. However, choosing right activities to be rewarded for and correct definitions of activity boundaries to assign badges, seems to be often a problem for web domains creators and there is just a few tools developed to solve this problem. In our work, we are going to create a front-end for a universal tool for assigning badges focusing on creating correct rules for assigning badges and creating design of these badges. Correct choice of activities users should be rewarded for and correct definition of boundaries for assigning certain badges will be supported by specifically proposed visualization of users’ activities, which will be provided by our tool.

Obtaining implicit feedback throughtout control devices

Date: April 2016
Experiment conductor: Tomáš Repiský
Supervisor: Ing. Peter Krátky
Short description: As our thesis is mainly focused on implicit feedback, this experiment will be focused on collecting data from mouse. User’s behaviour will be obsevrved during fifteen minute session of reading and browsing in self developed news portal. User will be asked to do two types of action during the browsing part. Main aim of this experiment is to obtain characteristic patters of movements, scrolling and positioning of mouse, so we can analyze the connection between these characteristics and user’s behaviour. As an extended measure to this data, we will use eye tracker device to track user’s gaze while doing tasks mentioned. As these data are not purely implicit, it can be used as a trustful source in process of evaluation.

Identification of Important Parts in the Source Code by Using Eye Tracking of a Programmer

Date: March 2016
Experiment conductor: Barbora Pavlíková
Supervisor: Martin Konôpka
Short description: Eye tracking finds its use in various research areas. Except of the usability studies, we can find it in psychology or user studies. Apart of that, it is also popular in studies of eye movements in programming. Many of such works are about reading a code fragments by programmers of various experience or about searching for links between source code elements. In programming we are looking at various parts of source code and those which we are paying attention to the most are kind of important for us. The word important means different things to everyone. It could be a part of code which contains main or difficult logic, or something that is hard to understand for us. In our work we are trying to identify these difficult parts in code only through tracking a programmer’s gaze. The difference from other studies is tracking gaze during programming so we are recording the whole process of creating code. This information could be then used in several ways. A team leader would be able to define weaknesses of his employee and arrange on improving his skills. Another use may be found in programming education. Tracking students during work on their tasks would be helpful to understand which sections are problematics for them so teachers would be able to adapt lessons according to the results.

Date: March 2016
Experiment conductor: Patrik Gajdošík
Supervisor: Márius Šajgalík
Short description: During UX testing in UX Class or in UX Lab, a huge amount of data is generated. This data contains useful information, like a repeating patterns, that could be used to better understand the behaviour of users during their work with applications (mainly the Web). One of the approaches to extract this information out of the datasets is to use neural networks. Nowadays, big variety of different architectures of neural network exists which could be used. The goal of our project is to analyze the existing architectures of neural networks and to build our own architecture (a module) that would merge/combine the work already done in this field and to apply it on the UX datasets created as a part of the projects done at ÚISI.

Experiment conductor: Mário Hunka
Supervisor: Martin Labaj
Short description: Parallel browsing is matter of course nowadays. The increasing use of tabs caused that management can be a problem for user and computer as well. Thats why its important to better understand user behavior and somehow optimalize and make the web browsing more effective. In our experiment, we will collect data for analysis. In this analysis, we will focus on the pages that were opened on a new tab, but never visited – so they are pointless. By eliminating this problem we can possibly speed up tabbed browsing. Of course, we will monitor if it has something in common with the using of mouse and keyboard. Finally, we want to propose an improvement or a feature that will ease web browsing.

Collecting EEG Data with P300 Speller

Date: March 2016
Experiment conductor: Patrik Berger
Supervisor: Róbert Móro
Short description: Our goal is to implement successful signal processing and P300 ERP classifying algorithm. We carry out an experiment in which we use EEG Epoc Emotiv device to collect data from participants using P300 speller application. We will use collected data to find out how accurate our algorithm is and furthermore, whether the data from Emotiv Epoc is good enough for detecting ERP like P300. Finally, we will compare accuracy of our algorithm with recent studies in this area and evaluate the results.

Music Watching Experiment for Emotion Detection using EPOC EEG Device

Date: March 2016
Experiment conductor: Tomáš Matlovič
Supervisor: Róbert Móro
Short description: We use EEG Epoc Emotiv device to collect data from participants while watching music videos. Music videos are chosen to evoke specific emotions. We use machine learning algorithms and try to classify those emotions. We plan to compare the accuracy of those algorithms and also with the method which comes with the Epoc Emotiv device. At the end, we will evaluate usability of an EEG Epoc device in measuring emotions by comparing its accuracy with FaceReader device.

Pupillary Response Experiment to Filters­-out the Luminosity Noise

Date: March 2016
Experiment conductor: Tomáš Juhaniak
Supervisor: prof. Ing. Mária Bieliková, PhD.
Short description: Information about cognitive load of a user can be very useful for appropriate system adaptation and personalization, especially if they can be measured in real time. As was shown by previous research, human cognitive load is reflected by pupillary response, measurable by eye­tracking devices. However, practical exploitation of this phenomenon (e.g. in adaptive systems or user studies) has been limited due to other factors that influence pupillary dilatation, namely changing luminosity of device screen. In this experiment, we conduct experiments with a pupillary response to filters­-out the luminosity noise caused by changing screen content. We show stimuli with different colors and structure and measure pupil dilation relative to these stimuli.

Congnitive Load, Visual Search, and Deception Detection

Date: February 2016
Experiment conductor: Tomáš Juhaniak, Mária Dragúnová, Metod Rybár
Supervisor: prof. Ing. Mária Bieliková, PhD.
Short description: We are collecting eye-tracking data from users, who are accomplishing visual search tasks, filling out online questionnaires and watching changing colors on screens. These data will be analyzed in couple of separate ways. First, we will use the data to find out, if we can standardize information from eyetracker about pupil and if so, this data will be used for pupil calibration and to differentiate between cognitive load changes and luminosity changes. Next, we use data from visual search to establish, if there is a link between visual search skills and speed of search of elements in web application. Last use of data will be to confirm hypothesis formerly confirmed in another experiment done in UX Lab, that we can create an automatic model of user deception in online questionnaires using mainly eye-tracker data.

Automation of Analysing Data from Usability Study with Eye-tracking

Date: February  2016
Experiment conductor: Vladimír Ľalík
Supervisor: Jakub Šimko
Short description: Usability of web interface is important because nowadays users are demanding of quality. Usability testing with gaze-tracking give us insight into user behaviour, but also give us a lot of data for analyzing.  Analyses of this data is usually qualitative and also can be affected by individual character of researcher. We provide method which try to automatically identify usability problems of websites from data gained through usability testing. Our method is based on relationship between metrics and patterns in eye-tracking data and specific usability problems.  The purpose of experiment is to prove our method for automated analyses. We prepared two different versions of tasks with different usability problems.

Personal Characteristics Links to Eye Movements

Date: February  2016
Experiment conductor: Metod Rybár, Viktor Svetský
Supervisor: prof. Ing. Mária Bieliková, PhD.
Short description: We are collecting eye-tracking data from users filling out psychological personality questionnaire. These questionnaires will be evaluated and linked with eye-tracking metrics to find out, if there are links between eye-movements and personalities characteristics. Questionnaires will be also evaluated as truthful or deceptive using psychological standard methods, and data from eye-trackers will be used to confirm links between implicit user feedback and deception.
