Eye-gaze interaction techniques for use in online games and environments for users with severe physical disabilities.
Vickers, Stephen (Thesis or dissertation / Doctoral / PhD)Multi-User Virtual Environments (MUVEs) and Massively Multi-player On- line Games (MMOGs) are a popular, immersive genre of computer game. For some disabled users, eye-gaze offers the only input modality with the potential ... -
For Your Eyes Only: Controlling 3D Online Games by Eye-Gaze
Istance, Howell; Hyrskykari, A.; Vickers, Stephen; Chaves, T. (Book chapter)Massively multiplayer online role-playing games, such as World of Warcraft, have become the most widespread 3D graphical environments with millions of active subscribers worldwide. People with severe motor impairments ... -
Gaze gestures or dwell based interaction?
Hyrskykari, Aulikki; Istance, Howell; Vickers, Stephen (Conference)The two cardinal problems recognized with gaze-based interaction techniques are: how to avoid unintentional commands, and how to overcome the limited accuracy of eye tracking. Gaze gestures are a relatively new technique ... -
Gazing into a Second Life: Gaze-driven adventures, control barriers, and the need for disability privacy in an online virtual world.
Vickers, Stephen; Istance, Howell; Bates, R. (Conference)Online virtual worlds such as Second Life and World of Warcraft offer users the chance to participate in potentially limitless virtual worlds, all via a standard desktop pc, mouse and keyboard. This paper addresses some ... -
An investigation into determining head pose for gaze estimation on unmodified mobile devices
Ackland, Stephen; Istance, Howell; Coupland, Simon; Vickers, Stephen (Conference)Traditionally, devices which are able to determine a users gaze are large, expensive and often restrictive. We investigate the prospect of using common webcams and mobile devices such as laptops, tablets and ... -
Keeping an eye on the game: Eye gaze interaction with massively multiplayer online games and virtual communities for motor impaired users.
Vickers, Stephen; Istance, Howell; Hyrskykari, A.; Ali, N.; Bates, R. (Conference)Online virtual communities are becoming increasingly popular both within the able-bodied and disabled user communities. These games assume the use of keyboard and mouse as standard input devices, which in some cases is ... -
Performing Locomotion Tasks in Immersive Computer Games with an Adapted Eye-Tracking Interface
Vickers, Stephen; Istance, Howell; Hyrskykari, Aulikki (Article)Young people with severe physical disabilities may benefit greatly from participating in immersive computer games. In-game tasks can be fun, engaging, educational, and socially interactive. But for those who are unable to ... -
Snap clutch, a moded approach to solving the Midas touch problem.
Istance, Howell; Bates, R.; Hyrskykari, A.; Vickers, Stephen (Conference)This paper proposes a simple approach to an old problem, that of the 'Midas Touch'. This uses modes to enable different types of mouse behavior to be emulated with gaze and by using gestures to switch between these modes. ... -
Towards dynamic accessibility through soft gaze gesture recognition
Shell, Jethro; Vickers, Stephen; Istance, Howell; Coupland, Simon (Conference)It is difficult for some sets of users with physical disabilities to operate standard input devices such as a keyboard and mouse. Eye gaze technologies and more specifically gaze gestures are emerging to assist such users. ... -
User performance of gaze-based interaction with on-line virtual communities.
Vickers, Stephen; Istance, Howell; Hyrskykari, A.; Ali, N. (Conference)We present the results of an investigation into gaze-based interaction techniques with on-line virtual communities. The purpose of this study was to gain a better understanding of user performance with a gaze interaction ... -
The validity of using non-representative users in gaze communication research.
Istance, Howell; Vickers, Stephen; Hyrskykari, Aulikki (Conference)Gaze-based interaction techniques have been investigated for the last two decades, and in many cases the evaluation of these has been based on trials with able-bodied users and conventional usability criteria, mainly ... -
What were we all looking at? Identifying objects of collective visual attention
Ma, Zhong; Vickers, Stephen; Istance, Howell; Ackland, Stephen; Zhao, Xinbo; Wang, Wenhu (Article)We aim to identify the salient objects in an image by applying a model of visual attention. We automate the process by predicting those objects in an image that are most likely to be the focus of someone’s visual attention. ...
