Hidden touchpad in concept cellphone

A cellphone with a touchpad – somehow that isn’t exactly new to me. This concept takes a slider form factor with a touchpad hidden underneath, using handwriting recognition software that translates finger strokes into letters, numbers, and symbols. No idea if the concept has made provisions for a stylus though as the finger is more or less an unrefined manner of getting the message across. Designed by Sang-Hoon Lee, this extremely basic handset just shoves the touchpad away when it is not in use, but other than that, nothing groundbreaking to crow about.
