Designed by Damian Kozlik this funky time piece called the x-watch is his concept at a universal time piece that can be used by the sighted and blind.
“X - watch” is universal and integrating L.E.D. timepiece. It can be used by sighted and blind people. Watch case and straps can be made of rubber. Dial is compounded of Leds. Mechanism of the watch (IC board) is placed under them.
How blind people can use it? It’s simple. It’s just to move a finger along the graduated watch glass. There are extruded Braille numbers. When a person touches highlighted panel hears a sound.
How it works? Every segment of the watch glass works like separated touch switch. There are two solutions possible:
1. Every panel works like capacitance touch switch. It needs only one electrode to function. The electrode can be placed behind a panel. It works using body capacitance. When a person touches it, it increases the capacitance and triggers the sound.
2. Every panel works like resistance touch switch. This solution needs metal units to function. There are two thin pieces of metal on the each panel. It works by lowering the resistance between them. It is much simpler in construction compared to the first solution. Placing a finger across the metal units achieves a turn on the sound. Removing the finger from the metal pieces turns the sound off.
