RESPONSIVE DYNAMIC THREE-DIMENSIOINAL TACTILE DISPLAY USING HYDROGEL |
| 摘要 |
A dynamic and refreshable three-dimensional tactile display uses stimulus sensitive hydrogel blocks as pixels to create a touch surface with elevations from a two-dimensional optical image or from stored data. The movable three-dimensional tactiles are powerful in teaching Science, Technology, Engineering, and Mathematics (STEM) materials to visually impaired and blind students. |
