Walabot is a cool gizmo that lets you see through walls with your smartphone
It detects pipes (metal and plastic), electrical wires, studs, and (presumably) the mummified remains of whatever poor soul was buried inside your living room's East wall some thousand years ago. It's both a cool "look at what my smartphone does!" showcase and a tool with practical purpose for any electrician.
Walabot is able to trace objects through cement, drywall, and also detect movements behind walls. As the technology becomes easier to integrate seamlessly with phones, clever developers could find ways to base fun games and useful apps around it.
Wouldn't it be cool to be able to chase your friends behind walls in multiplayer? Sounds like gaming from the future! Likewise, CEO Raviv Melamed envisions apps to help the blind avoid obstacles, help robots become autonomous, or alert you if something bad happens behind the wall.
