Abstract

This study presents two portable 4x4 solenoid-based tactile matrix display prototypes that use commercial of-the shelf (COTS) miniature DC solenoid actuators. Both prototypes are made from 16 pieces of an Open Frame Actuator Linear Mini
Push Pull Solenoid Electromagnet. Prototype 1 is a 4x4 Braille-like tactile matrix display with a faceplate of 50 mm side-length and 12 mm pin pitch. It is used to
study human’s ability to recognize Braille-like patterns by hand exploration of the tactile surface. On the other hand, the Prototype 2 is a miniaturized tactile display of
prototype 1 using a tactile matrix display miniaturization adapter that reduced the matrix pin surface area by around 8 times forming a 4x4 fingertip tactile matrix display. It is made up of flexible plastic tube fitted with a flexible wire connected to the plungers or pins of the tactile actuators. Moreover, it can also be combined with a tactile display simulator that scans a binary image to feel the surface area or edges of an image using Canny edge detector. The prototypes developed in this study might be used in the fields of telerobotics, Virtual Reality (VR), and Human-Computer Interaction (HCI).
