Meet Tap: a one-handed wearable Bluetooth keyboard that turns any surface into a typing surface, making it easier to interact with your smartphone. To get started, you will just have to put it on your hand and start typing with your right or left hand. You can turn the device on by tapping your thumb on a flat surface three times.
Tap can be paired with smartphones, tablets, and computers. It can be used to type in e-mail and messenger apps. What do you think? Are you impressed?
