Description of product:
X - watch is universal and integrating L.E.D. timepiece. It can be used by sighted and blind people. I observed that there are not many items addressed to this group.
Straps and casing of the X - watch can be made from rubber. Leds compose the dial. 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 sound. How it works? Every segment of the watch glass works like separated touch switch. There are two ways of solving this problem.
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. On the each panel are two thin pieces of metal. 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. As I know it won't be difficult to make it. Presented solutions are used in many different items (lamps, wall switches), however never applied in wrist watches.
