Towards Tangible Vision for the Visually Impaired through 2D Multiarray Braille Display

Seondae Kim, Yeongil Ryu, Jinsoo Cho, Eun-Seok Ryu
2019 Sensors  
Based on our previous research, the research using Kinect v2 and haptic device with 2D+ (RGB frame with depth) data has the limitations of slower operational speed while reconstructing object details.  ...  This paper presents two methodologies for delivering multimedia content to visually impaired people with the use of a haptic device and braille display.  ...  However, these methods are considerably slow for real-time haptic telepresence. Thus, this study focused on real-time 3D haptic telepresence with moderate quality.  ...
