Augmenting Tactile Interaction with Pressure-Based Input

The application of pressure (or force) through the fingers is an inherent part of investigative and interactive touch and yet remains underutilized in the field of Human Computer Interaction (HCI). To highlight the potential usefulness of pressure as an input or information channel, this paper includes example implementations and uses for pressure-based input in a variety of domains. These include the active application of force for the purposes of interacting with or controlling devices as well as passive detection of force as a means of monitoring behaviour in safety or healthcare scenarios. The use of pressure would allow for easier, more varied and more engaging interaction with devices, providing opportunities for new applications and services to be developed beyond what is currently possible.
