For my project I need a decent motion sensor that can detect not just my hand but also my fingers. Aside from Leap Motion, I already “played” with two motion sensors.
Intel Real Sense – I used this device only for competition. It’s a sensor camera from Intel that can detect hand, gesture, face, etc.
Microsoft Kinect – I used this device for my past DMSP project. As you may know, Kinect commonly used for a game in combination with Microsoft XBox. It can detect not just hand but also your full body.
I choose Leap Motion not just because it’s small and compact (so it can address my portability issue) but Leap Motion focus on hand and fingers. I think it will give better performance for my project.
