Summary of Tactile User Interfaces Techniques and Systems
ABSTRACT
Mental workload can be de.ned as the ratio of demand to allocated resources. Multiple-resource theory stresses the
importance of distribution of tasks and information across various human sensory channels to reduce mental workload. One
sensory channel that has been of interest since the late 1800s is touch. Unlike the more typical displays that target vision or
hearing, tactile displays present information to the user s sense of touch.We present a summary of different methods for tactile
display, historic and more recent systems that incorporate tactile display for information presentation, advantages and
disadvantages of targeting the tactile channel, and future directions in tactile display research.
