Microsoft has filed a patent application to create a tactile touchscreen, which gives users the illusion of touching the textures and bumps of a displayed image.
This upper plastic is manipulated through ultraviolet light from the screen beneath. It can become hard when one wavelength of ultraviolet light strikes a pixel and soft when another hits it, giving a sense of texture to the display.
Microsoft wishes to use the device as a large, table-sized computer, but it could be implemented in other ways in future.
If the display is successful, it could mean a huge improvement to touchscreen keyboards.
It would make them much more user friendly, allowing for faster typing and improving accessibility.
