TouchScope: A passive-haptic reading device to investigate tactile perception

The sense of touch is underrepresented in cognitive psychology research. One of the reasons is that controlling the timing of stimulus presentation, which is a hallmark of cognitive research, is significantly more difficult for tactile stimuli than visual or auditory stimuli. To contribute to the development of tactile research, we present a system to display tactile stimuli and collect response time with the capability for static and dynamic (passive haptic) stimuli presentation. While the system requires some construction, it can be put together with commercially available materials. We present here the hardware and software implementation and some examples of experiments.
