An alternative tracking method should be developed for Actuated Tangible User Interface Objects (ACTOs).
Alternative ways to retrieve the pose of our Actuated Tangible User Interface Objects (ACTOs) should be devised. At the moment a low-tech marker-based approach is used, but is restricted in application area. A more flexible approach is desirable, for example other visual solutions, like using a Microsoft Kinect, but also non-visual approaches could be suitable. The system can either be based on an Arduino-Board or an Android-Smartphone.
