We describe a system called Time Warp Football (TWF) which puts fans in control of the game watching experience. TWF uses annotated video streams to enable instantaneous forward and backward play-by-play navigation and on-demand switching between multiple camera angles. These features allow fans to easily watch and re-watch plays they are interested in from any camera angle. The annotations also allow for instantaneous game statistics whenever the fan desires. We took TWF into eleven different homes, connected it to the home TV, and provided a standard wireless video game controller to control the experience. Based on in-home user evaluations, we found that TWF provides an easy to learn interactive TV control system, effectively uses on screen prompts to enable groups to watch an interactive sporting event, and overall provides a successful interactive TV experience. |
