The Appcam is a new concept design for camera controls — and supposedly a patent — that aims to make handling DSLR and compact cameras more user friendly. Instead of having your camera settings hiding in different menus and changed using different controls (e.g. buttons, scroll wheels, dials), the Appcam turns them all into “apps” that sit conveniently on the LCD touchscreen. The apps/settings can be swapped in and out and reordered, and are adjusted using the physical scroll wheel next to it.
While this may definitely be a more user friendly interface for people who just got their first digital camera, it doesn’t seem like a good idea at all for seasoned DSLR users who already have all their controls where they need them.
