Here are some resources on my bachelor thesis at Fachhochschule OÖ, campus Hagenberg created in 2010 and 2011. I used the Qualcomm Augmented Reality SDK to control lamps and wall plug adapters using an Android smartphone. I think the SDK was later renamed to Vuforia.
Notes:This is me controlling a bunch of lamps and a computer monitor with an HTC Desire running my application. It practically turns the mobile phone into a seeing remote control for home automation. I used the Qualcomm AR SDK for the Augmented Reality part of the app. The home automation system is digitalSTROM. This app is part of my bachelor thesis I'm doing at the School of Informatics, Communications and Media in Hagenberg, Upper Austria. The text seen at the end reads: This application is based on the ImageTargets and Dominoes sample applications of the QCAR SDK. It uses the AChartEngine library by 4ViewSoft.
