* Herzfassen (Take Heart)

Herzfassen is a self-contained kinetic object that uses physical computing and biometric data to provide an aesthetic and sensual experience while maintaining an ordinary outer appearance: a metal bowl filled with water. When someone touches the handles, the human heartbeat is detected and represented through vibration and patterns on the water's surface. People are invited to explore and engage with their own physicality, as well as interact with others to create a social dynamic around the responsive object.

* HWD Corporation

HWD (hard-wired devices) Corporation is a collection of 100 electronic devices, each consisting of a travel alarm clock connected to a different game controller selected from the last 30 years of gaming culture. For each device a new interaction has been crafted by hardwiring the functions of the alarm clock onto the digital switches of the controller. As a result, the basic functions of the alarm clock, such as setting the time, can be controlled with the joysticks. This project is a journey through the history of game controllers, to celebrate both its revolutionary successes and its remarkable failures.

* Novel Taste Interaction: Adding Electric Taste to Foods and Drinks

We have developed devices for eating that can add electric taste to foods and drinks. These apparatuses enable us to instantly add, enhance, and delete certain flavors. With the help of these devices, we are able to enhance healthy low-salt meals, share flavors via YouTube, and detect whether or not someone is eating just by checking the change in the electric current.

* Umati: The Crowdsourcing Vending Machine

Umati is a crowdsourcing vending machine. Instead of inserting money into the machine to pay for snacks, users complete crowdsourcing tasks on an integrated touchscreen. Umati allows us to target specific communities who don't traditionally participate in crowd work with tasks suited to their skills and knowledge. We also target these communities with rewards that suit them and in locations where they have cognitive surplus. We deployed Umati at UC Berkeley and found we were able to cheaply crowdsource the grading of computer science exams, a task that cannot be accomplished on Amazon's Mechanical Turk.
