User interaction in hands-free gaming: a comparative study of gaze-voice and touchscreen interface control

Uludagli, Muhtar Cagkan
Acartürk, Cengiz
The goal of the present study is to contribute to the research on the use of eye tracking in hands-free gaming. We report the results of an experimental study by using a platform game designed by the authors. The game allowed gaze-voice command control, as well touchscreen control of the interface by the player. We employed a set of performance measures and we measured player engagement as an indicator of user experience. The findings revealed that the players did not improve in game performance when they used the gaze-voice control compared to the touchscreen control. On the other hand, they exhibited stronger engagement, which indicates the potential of gaze-voice combination as an acceptable interaction method compared to touchscreen in mobile games.


Eye tracking in multimodal comprehension of graphs
Acartürk, Cengiz (2012-07-31)
Eye tracking methodology has been a major empirical research approach for the study of online comprehension processes in reading and scene viewing. The use of eye tracking methodology for the study of diagrammatic representations, however, has been relatively limited so far. The investigation of specific types of diagrammatic representations, such as statistical graphs is even scarce. In this study, we propose eye tracking as an empirical research approach for a systematic analysis of multimodal comprehensi...
Design and development of a game based eye training program for children with low vision
Dönmez, Mehmet; Çağıltay, Kürşat; Department of Computer Education and Instructional Technology (2020)
This study explores the design principles of eye movement-based computer game applications as training material for children with low vision to enhance their vision skills. It aims to provide children with interactive materials to improve their vision. For the study, design-based research was employed in four phases, namely analysis, development, evaluation and testing, and documentation and reflection. In the analysis phase, a focus group meeting and interviews were conducted with experts from the field of...
An Eye-Tracking Analysis of Spatial Contiguity Effect in Educational Animations
Altan, Tuğba; Çağıltay, Kürşat (2015-08-07)
The purpose of this study is to examine spatial contiguity effect on multimedia learning with an instructional animation using eye-tracking. The research method was experimental method and the study was conducted with a user group consisting of 12 participants (6 female and 6 male). The data collection tools were a demographic survey, a prior knowledge test, a retention test and an eye-tracker. The collected data were analyzed using descriptive statistics and non-parametric statistics including Mann-Whitney...
Secondary-Task Effects on Learning With Multimedia: An Investigation Through Eye-Movement Analysis
Acartürk, Cengiz (2017-01-01)
This study investigates secondary-task interference on eye movements through learning with multimedia. We focus on the relationship between the influence of the secondary task on the eye movements of learners, and the learning outcomes as measured by retention, matching, and transfer. Half of the participants performed a spatial tapping task while studying the instructional materials, whereas the other half studied the materials, without spatial tapping. The results revealed suboptimal learning outcomes und...
Investigation of classroom management skills by using eye-tracking technology
Çoşkun, Atakan; Çağıltay, Kürşat; Department of Computer Education and Instructional Technology (2019)
This study investigates how a wearable eye tracker can be employed to assess and improve the visual attention of the faculty members in a higher education institution. Two experienced faculty members took part in the study. Both of them have been lecturing for more than ten years at the university, so they are experienced teachers. A wearable eye tracker was employed to assess and improve the participants’ visual attention in relation to classroom management skills. Besides, eye-tracking data were supported...
