Gesture control is a technology that has floated around for quite a while, but never quite reached mainstream acceptance. Wii Bowling was fun for a while, but we’re not regularly using gestures to open doors or order pizza just yet. Doing it yourself can be quite easy, however, as [RC Lover san] found with a barebones, hacky build.
Typically, when we think of gesture control, we envisage object tracking cameras or MEMS accelerometers. Instead, this build uses simple tilt switches, as you might find in a pinball machine from days of yore. Four of these are placed on a wrist-mounted device, allowing the user to tilt their arm to move an RC car in different directions. The tilt switches are easy to hack into the controller for a toy RC car, as they simply replace the existing buttons on the PCB.
It’s a project that goes to show that not everything has to be done with advanced sensors and complex algorithms. Sometimes, it can all be done with a handful of cheap switches and some ingenuity. Plus, using arm movements to scoot BB-8 around on the floor looks like great fun. We’ve seen other attempts to build simple gesture controls with pots, too. Video after the break.
