ABSTRACT
Text input with eye trackers can be implemented in many ways such as on-screen keyboards or context sensitive menu-selection techniques. We propose the use of off-screen targets and various schemes for decoding target hit sequences into text. Off-screen targets help to avoid the Midas' touch problem and conserve display area. However, the number and location of the off-screen targets is a major usability issue. We discuss the use of Morse code, our Minimal Device Independent Text Input Method (MDITIM), QuikWriting, and Cirrin-like target arrangements. Furthermore, we describe our experience with an experimental system that implements eye tracker controlled MDITIM for the Windows environment.

Gestural Text Input Using a Smartwatch
AVI '16: Proceedings of the International Working Conference on Advanced Visual InterfacesOne challenge with modern smartwatches is text input. In this paper we explore the use of gestural interaction with a smartwatch to support text input. The inertial measurement unit of a smartwatch is used to capture gestural interaction by a user, and ...
Stylus based text input using expanding CIRRIN
AVI '06: Proceedings of the working conference on Advanced visual interfacesCIRRIN [3] is a stylus based text input technique for mobile devices with a touch sensitive display. In this paper we explore the benefit of expanding the letters of CIRRIN to reduce the overall difficulty of selecting a letter. We adapted the existing ...
Eye-based head gestures
ETRA '12: Proceedings of the Symposium on Eye Tracking Research and ApplicationsA novel method for video-based head gesture recognition using eye information by an eye tracker has been proposed. The method uses a combination of gaze and eye movement to infer head gestures. Compared to other gesture-based methods a major advantage ...
