We propose self-sustainable, intelligent sensor systems that can be easily retrofitted onto current vehicles.

A CAPTCHA is a challenge-response test used on the Internet to prevent bots from accessing web services that are designed for humans. We are investigating Automatic Game based CAPTCHA Generation (AGCG), in which an AI system generates games that, when played, distinguish between humans and bots. The game based CAPTCHA takes advantage of not only the bots' difficulty performing pattern/object recognition, but also their lack of commonsense knowledge. Thus it is more secure but remains easy and fun for humans, compared to traditional visual based CAPTCHAs.

Working with Dr. Denise Herzing of the Wild Dolphin Project, we are creating wearable computers for conducting two-way communication experiments with cetaceans. With CHAT, one researcher uses the waterproof system to broadcast a sound, associated with an object with which dolphin's like to play. A second researcher, upon detecting the sound, passes the object to the first. The researchers pass objects back and forth, further associating the sound with the object. The goal is to see if the dolphins mimic the sound in order to "ask" for the play object.
