In this work, we demonstrate our concepts for transparent interaction panels in augmented-reality environments. Mobile devices can support interaction with head-mounted displays by providing additional input channels, such as touch & pen input and spatial device input, and also an additional, personal display. However, occlusion of the physical context, other people, or the virtual content can be problematic. To address this, we previously introduced CleAR Sight, a concept and research platform for transparent interaction panels to support interaction in HMD-based mixed reality. Here, we will demonstrate the different interaction and visualization techniques supported in CleAR Sight that facilitate basic manipulation, data exploration, and sketching & annotation for various use cases such as 3D volume visualization, collaborative data analysis, and smart home control.
