back to top  Soft-Spiky Mouse: Designing Aesthetic Forms of Computational Objects

The soft-spiky mouse changes its surface textures according to user behaviors. For example, if the user works with the mouse too long, the mouse displays spiky textures to raise awareness to the passage of time and/or the need for refreshment or break time. Alternatively, soft tactile feelings are displayed if the user completes a task, which would provide a pleasurable tactile feeling experienced as a form of encouragement. This project is a design exploration to synthesize a concept-driven design process and exploratory engagement with new forms and materials available to computational objects.

back to top  MobiSpray

MobiSpray is a novel interactive art tool for creating ubiquitous ephemeral digital art. A mobile phone is employed as a virtual spray can to deposit digital paint onto the physical environment via large-scale projections. The gesture-based control of the mobile phone provides a natural pointing mechanism for the virtual spray can for painting anywhere, anytime on anything.

back to top  Energy Mementos

Energy Mementos are provocative objects designed to explore the energy analog of physical mementos or keepsakes. For example, shaking the Shake-Light Bottle collects energy and stores energy metadata about how it was collected. Removing the cap activates the collected energy, causing the bottle to glow in unique patterns based on the energy metadata (e.g., the age of the energy). One usage scenario is giving the Energy Memento as a gift of one's own energy. Energy Mementos raise questions such as: Can we become attached to particular energies? How can and cannot we experience energy as we experience material things?

back to top  Cally and Callo: The Robot Cell Phone

The project "Cally and Callo" aims to integrate human social characteristics with mobile phone services. The prototypes are a combination of an old-school smartphone and a robot kit. A phone device is the robot face and also functions as the "brain." The mobile apps are built on Symbian S60 to handle phone native functionalities such as telephony, SMS, and video call. Cally and Callo register various "facial" and "body" expressions to indicate incoming calls from different groups of people. The robots can recognize emoticons and user-created gesture animations from SMS text messages. What's more, the two Callo robots can synchronize their gestures: If you set a movement for your Callo, the robot on the other end of the video call moves in exactly the same way.
