Tactile and Multimodal Displays

In this area my objective is to create tactile language, warnings and alerts.

Tactile language is used as a substitute to visual and auditory languages when either of the modalities is overloaded of impaired. It is usually more limited, i.e., more of a command language than a natural form of expression.

Other means of use of tactile are for warning and alerts. These types of cues can be simple (binary) or complex (with additional meaning, based on the structure of signal or its location).

Tactile displays have not been implemented as much as displays in other modalities. There is a variety of technologies to stimulate tactile sensations such as pressure, vibration and temperature. Our teams aims to bridge this gap by looking at novel tactile displays (e.g., our TTD), various setups and applications for vibrotactile displays (e.g., Salzer and Oron-Gilad, 2015), and behavioral and fMRI studies to learn more about the tactile modality (modalities), like Salzer, Oron-Gilad and Henik, 2014.

A good starting point on Tactile applications would be to revisit old work of R.D. Gilson’s  (he was a student at Geldard’s lab way back in the late 60s of the 20th century). He was my mentor on tactile displays and he introduced me to this fascinating area.
