Design submitted by Sam from Germany.
Sam transferred the “neck bones” of a crash test dummy and the recognizable camera marker to this wrist watch. The display is a derivation of the before mentioned camera marker.
There are three analog watch hands for hours, minutes and seconds and a dial in the same colors. The glass plate on the display carries an LCD display. It is normally off and with the push of a button, it lets your see the date or use a stop watch. To perfect the crash test theme, Sam thought about according sensory. In the end, he decided for an ultrasonic distance meter. This gives the wearer the opportunity to measure the distance of objects as well as calculating their velocity when moving towards of away from the wearer. The distance meter data is also shown on the LCD display.
The distance meter works as follows: The sensory, which is placed above the strap and pointing away from the wearer, emits ultrasonic waves and the internal stop watch gets started. The ultrasonic waves sooner or later hit an object and get reflected by it. The reflected waves reach the sensory again and the stop watch stops. The resulting time multiplied with the sound velocity and then divided by 2 results to the passed distance (d=vt/2). As long as the wearer holds the button, this process gets repeated in a high frequency and the data becomes more accurate. The zero point of the measurement can be set individually (let it be center of the watch or your wrists outer face for example). If the object is moving towards the wearer or away from him/her, the distance difference in a certain time gets measured and the velocity gets calculated (v=Δd/t).
With a proper software, the wearer can also calculate the speed of the car he/she is in for example (using the tachometer principle of a known distance combined with the stop watch) or the distance of a thunder storm (using the stop watch and automatically multiplying the time between flash and thunder with sonic velocity)/ Or one can calculate the average walking speed in a known distance and extrapolate the necessary time for future walks.
This watch design is a combination of a geeky and extrovert watch. There are some different colored straps to appeal to a wider range of people. It is a watch with a high value of recognition and a clever usage.
