Study on Human Fingers Perception over Textured Surfaces for the Textural Applications in Haptics Technology

Abstract

Haptics technology uses skin as a source for feedback and helps in the perception of the stimulus. There are various types of actuators or displays used in haptics perception, like electro-tactile, vibrotactile, thermal coil and physical pins. These actuators require larger neural density for being used as an application. Hairy and Non-Hairy skin, its neural density pattern must be observed for perception memory applications. The textural applications in haptics technology are one of the kinds which use skin and its perception levels. The paper discusses the behaviour of fingertips and fingertip’s skin behaviour pattern towards textural applications in tactile feedback. The experiment in the paper uses psychophysical assumptions and single-blinded method of perception over six human participants under three environmental condition, and 10 stimuli which are used in everyday activity. The experimental result focuses on the perception time and perception memory of human fingertips, which will a comparative data with real-time haptic feedback. The experimental methods discussed in the paper addresses low-cost perception experiment for a preliminary study of haptics textural applications.
