The Media Interaction Lab will present one CHI full-paper and one work in progress. In the paper, we present Geckos, a new type of tangible objects which are tracked using a Force-Sensitive Resistance sensor. Geckos are based on low-cost permanent magnets and can also be used on non-horizontal surfaces. Unique pressure footprints are used to identify each tangible Gecko. Two types of tangible object designs are presented: Using a single magnet in combination with felt pads provides new pressure-based interaction modalities. Using multiple separate magnets it is possible to change the marker footprint dynamically and create new haptic experiences. The tangible object design and interaction are illustrated with example applications. We also give details on the feasibility and benefits of our tracking approach and show compatibility with other tracking technologies.
The work-in-progress submission is about the design and implementation of Move-It, a system that combines the affordances of note taking on paper with the capabilities of computer systems. We will present how common Post-It® notes can be actuated by shape memory alloys and become interactive sticky notes giving active physical feedback.
