This paper discusses state-of-the-art tactile displays fabricated by a micro-electronic-
mechanical-system (MEMS). A tactile display conveys tactile sensations to users by using …

In the era of ubiquitous computing with flourished visual displays in our surroundings, the
application of haptic feedback technology still remains in its infancy. Bridging the gap …

In this study, a new Braille display is constructed based on the vibration of a Shape Memory
Alloy (SMA) wire. To present Braille information, a vibration actuator is used instead of …

This chapter presents innovative and highly integrated actuator concepts based on smart
material transducers. This term refers to those active materials which react to an electrical …

With the current development of society, ensuring traffic and walking safety for the visually
impaired is becoming increasingly important. We propose a wearable system based on a …

With the widespread availability of computers and mobile devices, we use them for daily
communication by exchanging visual and verbal/non-verbal media. We obtain various …

In this paper a concept for hardware realization of graphic tactile display for visually
impaired peoples is presented. For realization of tactile actuators bi-stable, solenoids and …

This paper describes the design of a piezoelectric-driven hydraulically amplified Braille-
flexible bump device that enables the flexible formation of Braille characters. A piezoelectric …

Deducing the input signal for a tactile display to present the target surface (ie, solving the
inverse problem for tactile displays) is challenging. We proposed the encoding and …

This paper discusses the design and prototype implementation of a Sign Language to
Braille Converter as well as an English Language to Braille Converter. This prototype can …
