What if you could control a vehicle with just one button and gestures? That was a challenge we explored and prototyped in 2007 for Cadillac. Here is the text from the patent application. “A key fob for a vehicle that provides a certain vehicle function depending on the motion applied to the key fob. The key fob includes a switch that is pressed when the vehicle operator wishes to transmit a command. Pressing the switch causes a device, such as a camera or accelerometer, to be put in a motion detecting mode, where a subsequent motion of the key fob causes the key fob to transmit a command associated with that motion. For example, the vehicle operator can press the switch on the key fob and make an upward motion, which will cause the vehicle door locks to unlock. Likewise, pressing the switch on the key fob and making a downward motion may cause the door locks to lock.”
