A Silent Alarm Clock - Sessiz Alarm Saati by Johan Brengesjo
Alarm clocks usually jolt us awake leading us to reach for the almighty snooze button. Silence is a conceptual alarm clock that allows you to program multiple alarms and wakes you without any sound. Each person wears a wireless rubber ring with an integrated vibration device that generates a tactile alarm. The snooze function is engaged by shaking your hand. However, each successive time you want to snooze, more movement is required, making sure you get to work on time.
This is an interesting idea, and I especially like that you have to work harder each time you want to snooze the alarm, but I have my doubts about a vibrating ring being enough to wake me up. Maybe if it were to deliver a jolt of electricity when I try to snooze it a fourth time…
