Designing Seamless Tangible Interactions on Portable Displays
1 day Studio-Workshop at TEI'16
February 14, 2016
Eindhoven, the Netherlands
The analog Hall-sensor grid, GaussSense, is a thin-form magnetic-field camera technology for designing expressive occlusion-free, near-surface tangible interactions on conventional portable displays. The studio will provide hands-on experiences that combine physical designs and the GaussSense technology. Through a series of brainstorming and making exercises, participants will learn how to exploit natural hand and micro interactions through designing the expressions and affordances of physical objects, and know how to utilize physical constraints to provide additional kinesthetic awareness and haptic feedback. The exercises will be including form-giving, electronic prototyping, and hacking physical toys that are prepared by either the organizers or participants.

Tangible user interface (TUI) has been enabled on ubiquitous portable displays to facilitate the interactions between digital content and general users. Since the object tracking capability of the built-in sensors is limited, designers require to use more metaphors and spatial mappings to fill the gaps between virtual and real worlds, meanwhile increase users' cognitive efforts.

Our previous research has presented a system of seamless tangible interaction designs based on magnetics and the thin-form magnetic-field camera, GaussSense. With a dense grid of Hall-sensor deployed, GaussSense functions as a short-depth camera that tracks the 3D position and orientation, shape, and ID of multiple magnetic objects nearby it by seeing the magnetic field distribution in real-time; GaussSense also functions as an X-ray camera that sees the magnetic object, which can be coated in non-ferrous materials and/or expressive forms, through users hands. Therefore, GaussSense can be attached to the back of prevalent portable displays for TUI design, or attached to human body for on-body input. The proposed magnetic TUI designs and sensing techniques support designers to develop natural and intuitive tangible user interfaces to enrich how individuals interact with the portable displays.
In TEI 2016, we organize GaussStudio: designing seamless tangible interactions on portable displays. We will provide hands-on experiences for participants about how to use magnetics to design and realize their ideas through building seamless and expressive tangible interfaces on conventional portable displays. Through a series of form giving, electronic prototyping, and toys hacking exercises, participants will learn how to exploit natural hand and micro interactions through designing the expressions and affordances of physical objects, and know how to utilize physical constraints to provide additional kinesthetic awareness and haptic feedback to enrich the tangible and embodied interaction design.

Our Studio-Workshop will go through five phases: a warm up session, hands-on tutorial session, a brainstorming session, a paring and making session, and a sharing period.
Hour 1 – warm up
After the organizers introduce themselves, relevant fundamental knowledge, including the overview, available interaction set and limitations of this technology, is presented through a 45-minute introduction.
Hour 2-3 – hands-on tutorial
The organizer will provide hands-on, step-by-step tutorial on the GaussSense SDK.
Hour 4 – brainstorming through making
Participants build lo-fi prototypes with their hands. Paper clay, various kinds of magnet, stacks of 3M post-it memos, and white paper will be distributed to the attendee.
Hour 5-6 – paring and making hi-fi prototypes
Participants will pair up with another studio attendee to combine their creations and make hi-fi prototypes together.
Hour 7-8 – sharing
After the making session, participants will present their hi-fi prototypes in the sharing session.
