Watch This Touchscreen Transform Into a Physical Keyboard
For tablet - and smartphone -owners who love their touchscreens  but occasionally yearn for the tactile feel of a physical keyboard, Fremont, Calif.-based company Tactus has unveiled new technology that unites both features on one gadget.
It developed a tactile user interface for touchscreen devices: transparent physical buttons that emerge from a tablet or smartphone's surface on demand. To see the technology in action, watch the video here .
"With the buttons enabled, users can push and type or rest their fingers as they would with any physical button or keyboard," Tactus explains on its website . "When the buttons are disabled, they recede into the screen, becoming invisible and leaving a smooth, seamless flat touchscreen with maximum viewing area."
This "Tactile Layer" technology integrates with a touchscreen device by replacing its cover glass.
While current smartphones include the option of haptic feedback, which causes on-screen keys to vibrate upon touch, Tactus says it's not the same as physical buttons.
