The tilt alarm is a personal project. It is an alarm clock without a button for setting the alarm. You can turn the alarm on by turning the alarm clock 90 degrees. Depending on the direction you lay down, the alarm could be turned to either its left or right side accordingly so that the user always sees the time from the most comfortable orientation. The user can disable the alarm by turning the alarm clock back to its original orientation. The alarm clock's motion syncs with the user's laying down and getting up motion through this design. I hope the operation of this alarm clock is more intuitive than traditional ones.
