Virtual object manipulation is required in a wide variety of application domains. From city planning [1] and CAD in immersive virtual reality [2], interior design [3] reality and virtual prototyping [4] , to manipulating a multi-dimensional dataset for scientific data exploration [5], educational applications [6], medical training [7] and even sandtray therapy [8] . There is, in all these application domains, a demand for low-cost, intuitive and fatigue-free control of six degrees of freedom

Examples of situations where there is a need to interact in 3D from a distance include the following: Education A professor is demonstrating human anatomy by displaying 3D graphics on a large projector screen. He uses his device to rotate the model and answer questions from the students. The nature of the device allows him to leave the podium and approach the students while still being able to interact with the model, thus making the class more engaging. Engineering An engineer is showing a 3D model of her latest design to team-mates. The device is used to rotate and translate the model, define slicing planes to inspect the interior and discuss the design with other participants. Entertainment A group of children are playing a game in a museum while at the same time learning about physics by interacting with wooden blocks on a sandbox-like 3D environment on a large screen. Abstract INSPECT is a novel interaction technique for 3D object manipulation using a rotationonly tracked touch panel. Motivated by the applicability of the technique on smartphones, we explore this design space by introducing a way to map the available degrees of freedom and discuss the design decisions that were made. We subjected INSPECT to a formal user study against a baseline wand interaction technique using a Polhemus tracker. Results show that INSPECT is 12% faster in a 3D translation task while at the same time being 40% more accurate. INSPECT also performed similar to the wand at a 3D rotation task and was preferred by the users overall. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
