Paradox Computer Inc. has worked for years for R&D developments.
Our first patent was made for Vibrating Braille Technology, which transform
vibration haptic into braille language. Users can notify time & date just by
putting two fingers on the top of the watch for 4 seconds.
Midnight can be written as one-two-zero-zero whereas Two a-clock can be written as
zero-two-zero-zero. Because time & date are made of 4 numerical digits,
braille cells will vibrate 4 times.
