    Gazing into a Second Life: Gaze-driven adventures, control barriers, and the need for disability privacy in an online virtual world.
    (2008) Vickers, Stephen; Istance, Howell; Bates, R.
    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 of the interaction barriers and privacy concerns that people with disabilities may encounter when using these worlds, and introduces an avatar Turing test that should be passed for worlds to be accessible for all users. The paper then focuses on the needs of high-level motor disabled users who may use gaze control as an input modality for computer interaction. A taxonomy and survey of interaction are introduced, and an experiment in gaze based interaction is conducted within these virtual worlds. The results of the survey highlight the barriers where people with disabilities cannot interact as efficiently as able-bodied users. Finally, the paper discusses methods for enabling gaze based interaction for high-level motor disabled users and calls for game designers to consider disabled users when designing game interfaces.

    Keeping an eye on the game: Eye gaze interaction with massively multiplayer online games and virtual communities for motor impaired users.
    (2008) Vickers, Stephen; Istance, Howell; Hyrskykari, A.; Ali, N.; Bates, R.
    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 not appropriate for users with a disability. This paper explores gaze-based interaction methods and highlights the problems associated with gaze control of online virtual worlds. The paper then presents a novel ‘Snap Clutch’ software tool that addresses these problems and enables gaze control. The tool is tested with an experiment showing that effective gaze control is possible although task times are longer. Errors caused by gaze control are identified and potential methods for reducing these are discussed. Finally, the paper demonstrates that gaze driven locomotion can potentially achieve parity with mouse and keyboard driven locomotion, and shows that gaze is a viable modality for game based locomotion both for able-bodied and disabled users alike.

    Snap clutch, a moded approach to solving the Midas touch problem.
    (ACM, 2008) Istance, Howell; Bates, R.; Hyrskykari, A.; Vickers, Stephen
    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. A light weight gesture is also used to switch gaze control off when it is not needed, thereby removing a major cause of the problem. The ideas have been trialed in Second Life, which is characterized by a feature-rich of set of interaction techniques and a 3D graphical world. The use of gaze with this type of virtual community is of great relevance to severely disabled people as it can enable them to be in the community on a similar basis to able-bodied participants. The assumption here though is that this group will use gaze as a single modality and that dwell will be an important selection technique. The Midas Touch Problem needs to be considered in the context of fast dwell-based interaction. The solution proposed here, Snap Clutch, is incorporated into the mouse emulator software. The user trials reported here show this to be a very promising way in dealing with some of the interaction problems that users of these complex interfaces face when using gaze by dwell.
