Introducing the modifier tactile pattern for vibrotactile communication

Abstract

We introduce the concept of “Modifier Tactile Pattern” as a pattern that modifies the interpretation of other elements that compose a Tacton or an entire tactile message. This concept was inspired by the prefixation strategies of the Braille system. We also show how to design tactile languages applying the concept of Modifier by following methodologies and approaches of Tacton design that already exist in literature. Then a modifier-based tactile language is designed and assessed in a user study.
