How does the Nintendo DSi know when you're tilting it? Hi Corporation licensed software from Realeyes 3D that uses the DSi's camera to sense motion. Let's examine how Hi Games used the Motion Cortex code in the four mini-games that make up Katamuction."
It seems a number of developers have been taken with the idea of using the DSi's cameras to simulate motion-based gameplay, but unfortunately many of these games end up feeling like gimmicky tech-demos more than actually fun games. HI Games & Publishing's latest attempt makes for an uneven experience with one of the four games in Katamuction providing a truly entertaining experience, whilst the others range from okay to frustrating due to their implementation of the camera-based controls.
The Nintendo DSi can do motion control with the camera and Motion Cortex software from Realeyes3D. HI Games used both to make Katamuction, a DSiWare game which has players run from a hungry Tyrannosaurus Rex.
