London: Taking your own photo using a camera timer is fraught with problems - not least making sure you are all in shot before the timer runs out. But we have a solution now.
Shaowe Chu at the University of Tsukuba in Japan has developed a digital camera whose gesture recognition software lets people control the camera remotely, using only a wave of a hand, reports New scientist.
The system only works with cameras equipped with viewfinders that can be flipped round to face the front, or those that have a viewfinder on the front and the back.
This lets the user see the frame and control virtual buttons that appear on screen by moving their hand over where they appear in the frame.
One, which Chu calls the “hover button”, operates the shutter.
When a hand within the viewfinder’s frame points a finger at this floating icon and stays on it for 1 second, the camera initiates a short countdown sequence before the shot is taken.
Panning and tilting is achieved by sliding a finger up and down, left and right, over a cross-hair icon displayed on the viewfinder’s screen, which is picked up and acted on by an algorithm that detects movement.
A prototype of the system will be presented in July at the Human-Computer Interaction conference in Orlando, Florida.
