GaussBricks is a novel building-block system for tangible interaction design that enables real-time constructive tangible interactions on portable displays. The simple mechanical design of the magnetic building blocks facilitates the construction of configurable forms. The forms constructed from the magnetic building blocks, which are connected by magnetic joints, allow users to stably manipulate them with various elastic force-feedback mechanisms. With an analog Hall-sensor grid mounted to its back, a portable display determines the geometrical configuration and detects various user interactions in real time. This work also introduces several methods to enable actuated shape changing, multi-touch input, and display capabilities in the constructed form. The proposed building-block system enriches how individuals physically interact with portable displays.

Gesture-based interaction methods are now supported by a wide variety of devices, such as capacitive trackpads and capacitive 3D gesture-recognition systems. When interacting with such proximity-sensing surfaces, users face the challenge that the supported gestures are not directly apparent. Rainbowfish tackles this problem by combining a semi-transparent capacitive proximity-sensing surface with an LED array. The LEDs are used to visually indicate possible gestural movements and provide feedback on the current interaction status. Aside from computer-centered interaction, Rainbowfish can be used as a low-cost gesture-recognition system for home automation, for example as a gesture-controllable door opener.

What would it be like to allow people to see each other through an interactive transparent display? We propose a concept called TransWall, which allows users to experience collocated face-to-face multimodal interactions through a transparent display. To implement this concept, we made a see-through display touchable on both sides and added more interaction possibilities, such as audio capabilities and vibrotactile feedback. TransWall enables people to see, hear, or even touch other people through the display while enjoying both the content and the interpersonal communication.

Opera singers can use the Vocal Chorder, a large interactive instrument, to add new elements to their performance. The device allows performers to interactively accompany themselves through pushing, leaning on, and bending steel wires. Audience members can also use the instrument to interact with the operatic voice. When a person steps into the Vocal Chorder, its wires enable full-body interaction to explore the sounds and the interactive pyramid projected in front of the performer. It is a visualization of the child in Ray Bradbury's short story "Tomorrow's Child," born in another dimension and perceivable by its parents only as a pyramid.
