The manufacturers of the Autographer call it the "world's first intelligent, wearable camera." Clip it on your pocket: Using five sensors that detect changes in light, temperature, direction, color and how fast it is moving, the camera determines the best time to take a picture, up to 2,000 photos a day. It weighs only 2 oz. and measures 1.5 x 3.5 x 0.9 in.; it comes with 8GB of storage and a 5-megapixel low-light sensor.
The Autographer has a built-in GPS unit and a lens capable of taking 136-degree photos. An iPhone app lets you preview and share your images, check the camera battery, set modes and adjust capture settings. Desktop software lets you view, share and edit your images from your computer.
