I recently developed a sample application for Google Glass using Vuforia 3.0 (without Unity) and its working great. But after a couple of minutes of usages the Glass gets hot and the Glass needs to cool down to work properly. Im just using 2 image targets which are augmented by 2D Images. Is there a way to compensate for this? Is it maybe possible to reduce the recognition interval or any other parameter to keep the glass going for a longer time ?
