3D Gesture-Recognition Technology For Smartphones

Gesture recognition is a section of computer science that can interpret human gestures via mathematical algorithms.It enables humans to communicate with the machines without any mechanical devices.Using camera’s and computer vision algorithms,many approaches were made to interpret the sign language.

Not only computers,the gesture recognition technology can be used in smart-phones too.when you cant get to the phone,just imagine how comfortable it would be to attend your phone by just waving your hand or by any other gesture.

Previously,Korean company Pantech has released a smart-phone in 2011 that could use its camera to recognize simple gestures.However,the technology hasn’t reached many smart-phone users.Microsoft’s Kinect and the soon-to-be-released Leap Motion have come up together to push 3D gesture-recognition technology into the mainstream.But the usage if infrared laser to capture the detailed information about a scene needs more power from the mobile.

Now,A new device named 3dim that enables a smart-phone’s camera to recognize gestures is developed by Andrea Colaço and team at the Massachusetts Institute of Technology Media Lab in Cambridge.

The system enhances the standard smartphone cameras with a low-powered infrared light source and looks for the mathematical structures in the 2D image data to simplify the scene.The objects distance from the phone can be measured with the difference in time taken by the infrared light to bounce off objects and return to the camera.

This approach allows 3dim to operate in complex environments.The scientists claim that this technology doesn’t ruin your battery life as it demands only about one-seventh of the power utilized by a standard smart-phone camera i.e.,only a few milliwatts of additional power is required from the phone.

The research team presented 3dim at the  MIT $100K Entrepreneurship competition.It could not only be included in the next generation of smartphones but also can be adapted to work with wearable devices like google glass.

Wait for it,you can play with your smart-phone’s with a simple hand or face gesture of yours!
