Abstract

A refreshable haptic display includes an actuator (35) using one or more shape memory springs (46). A shape memory spring (46) is heated and urges a pin (34) to a first or extended position. The pin (34) may be supported in the first position (34a) by a supporting mechanism. The shape memory spring (46) is heated electrically (48). The device may be used for haptic displays provided in a user interface from a software program and display controller.
