Micro-Actuation Principles for High-resolution Graphic Tactile Displays
نویسندگان
چکیده
One of the possible actuation principles which were found to be the most promising candidates for highresolution tactile displays is presented. The actuators are based on SMA wire, which includes a clamping mechanism, to overcome high energy consumption and its consequences. A module consisting of 16 taxels in one row, with a distance of 2.54mm separating the taxels, was designed and produced with μEDM technology. Special setting and resetting procedures have been developed with the purpose of overcoming friction problems that were noticed during the first tests. The design and the procedures are presented.

Tactile Displays: a short overview and recent developments
Tactation is the sensation perceived by the sense of touch. Tactation is based on the skin receptors. The skin nerves can be stimulated by mechanical, electrical or thermal stimuli. Apart from fibers for pain, skin has six more types of receptors. A review of the state of the art concerning the physiological and technological principles, considerations and characteristics, as well as latest imp...
متن کاملTactile displays: Overview and recent advances
Tactation is the sensation perceived by the sense of touch, and is based on the skin’s receptors. Touch is a common medium used by the general population and the sensory impaired. Tactile substitution can be used by the blind or deaf in order to: (a) enhance access to computer graphical user interfaces and (b) enhance mobility in controlled environments. The skin nerves can be stimulated throug...

This paper presents a study on the effects of tactile fidelitythe degree of exactness with which real-world tactile stimuli are reproducedon the perception of single-finger and whole-hand touch gestures. We developed an armbased tactile display consisting of a four-by-three grid of linear resonant actuator motors to facilitate our investigation. This device supported two extreme levels of tac...

To allow for producing high quality tactile graphics, the involvement of blind users in the production process can be a very vital approach. In this paper, we describe a collaborative tactile graphic workstation. Thereby, a sighted user works with a conventional vector graphic production software while a blind user can edit the same graphic on a two-dimensional pin-matrix device at the same tim...
متن کاملDynamic Characteristics of a Hydraulic Amplification Mechanism for Large Displacement Actuators Systems
We have developed a hydraulic displacement amplification mechanism (HDAM) and studied its dynamic response when combined with a piezoelectric actuator. The HDAM consists of an incompressible fluid sealed in a microcavity by two largely deformable polydimethylsiloxane (PDMS) membranes. The geometry with input and output surfaces having different cross-sectional areas creates amplification. By co...
