alarm clock for blind people

After many consultations with these people, I tried to change standard type of funkcion and improve it for easier using.

The principle of operation:
The small pointer is going inside the dial and big pointer is going around the dial, and that's the result for exact reading of time. Than there is a helpfull fact, that pointers are concave curved and direct your finger to the top of pointer.If you would like to find number 12, you can touch three bumps on dial or nick on the rim.

You can set the timing of allarm by moving steel part around the rim.It is moving and clicking minute by minute.
When you get up, you deactivate alarm by pushing in the midle of dial. If you would like to activate it again, just push the button on the back of the alarm clock.
