Abstract

Motivation - Our goal was to design a thermal tactile display based on the thermal grill illusion sensation (created with spatially adjacent warm and cold stimuli), and to explore perception of information with such display. Research approach - A prototype of a Thermoelectric Tactile Display (TTD) was developed, based on Thermoelectric Coolers (TEC) Peltier technology. Temporal and spatial manipulations of signals will lead to definition of optimal TTD parameters, and to mapping of the sensory perception. Findings - Currently at initial stages of the experimentation of TTD prototype, findings indicate clear and distinguishable sensations. The TTD's performance is supported by an analytical model. Research Limitations - Pilot study with limited number of participants Originality - This study expands the knowledge and availability of tactile-modalities. The majority of tactile interfaces used in research and applied settings are based on vibration and pressure. No previous references show the use of thermal displays as a stand-alone signal source, nor is there evidence of the use of the thermal grill illusion for that purpose. It is the first use of TEC technology for generating thermal grill stimuli. Take away message - TTD opens a new channel of tactile communication, whose optimal parameters and functionality needs yet to be fully determined.
