Evaluation of Tooth-Click Triggering and Speech Recognition in Assistive Technology for Computer Access

Abstract

Tooth-click detection performed better than speech recognition when paired with both the optical head mouse and the gyrometer head mouse. Such a system may improve computer access for people with tetraplegia.

Laser scanner based foot motion detection for intuitive robot user interface system

“…Tooth-clicks can be an input medium for user interface systems, as proposed by Tyler Simpson et al [6]. They developed a computer access device for people with tetraplegia, which means loss of motor function in both arms and both legs.…”

Multimodal Hand and Foot Gesture Interaction for Handheld Devices

“…The presence of computing power ranging from intelligent walls to handheld interfaces demand intuitive ways of interaction and human-centered design approaches. For effective human-machine communications researchers are considering different combinations of modality and multisensory approaches such as hand gesture , tooth clicks [Simpson et al 2010], eye blink [Grauman Authors' addresses: Z.

Typing with eye-gaze and tooth-clicks

“…The work in [Simpson et al 2008] presents an evaluation of the TC in a center-out reaction task and a planned movement icon manipulation task, while the work in [Simpson et al 2010] further classifies the performance of the TC in the center-out task. In the pilot study described in this paper, we evaluated the performance of the TC when used by able-bodied subjects for text entry through a virtual keyboard, and compared it with that of DT.…”

“…With severely motor-impaired individuals as the target population of our work, we proposed to use a "tooth-clicker" (TC) device [Simpson et al 2010] as a gaze-independent mechanism for generating activation commands (mouse clicks). This noninvasive, lightweight, discrete and wireless device ( Figure 1) is positioned on the ear and has a contoured arm that wraps around the ear (similarly to a hearing aid).…”
