ACHIEVEMENTS

• Architected and implemented ShadowChaser3d, an innovative golf swing training application that overlays a 3d animation of a perfect golf swing over still or video images of the student golfer.
• Created Animailer, a web site and underlying technology that enables people to send animated 3d characters and live data applets embedded in e-mail messages. The recipient does not need a plug-in.
• Conceived and implemented in CosmoPlayer 2.0/NT, a method of streaming animation data into VRML scenes resulting in Cosmo’s Bliss.com VRML multicast showpiece at Siggraph ‘97.
• Designed the interaction metaphors and user interface of InPerson, a desktop video conferencing application. This innovative, easy-to-use application generated approximately $3M in software revenue.
• Invented enabling technology for collaborative tools including a shared presentation tool and a shared movie player. The latter, with InPerson, became the cornerstone of Sprint’s Drums offering.
