Abstract

Tactile feedback has the potential to provide rich communication in a range of embedded applications, but this requires a finger restraint that is effective and practical for integration into a handheld device. This paper investigates an aperture-based restraint, a simple conical hole, used to prevent unwanted motion of the finger and to provide access to the tactile device. A range of aperture sizes were tested with both the index finger and thumb using a tactile display that applies tangential skin displacement. The aperture restraint was found to be effective, comparable to a traditional thimble-type restraint, with larger apertures performing better. There was no significant interaction between finger size and aperture size, meaning that the same aperture could be used for a wide range of fingers sizes.
