Watch A Video

Download a 12GB video in AVI format from my server. It is approximately 4-5 hours in length, simply a video of someone sleeping. Record the time into the video of every change in sleeping position, disturbance etc (i.e. anything that is not simply static deep sleep). Record in this format: Event Type: Time start: Duration: For example, if the person rolls over at 1 hour, 30 minutes and 22 seconds into the video, and the rollover to back to stable sleep take 7 seconds, you would record it as follows: rollover, 1:30:22, 0:00:07 Events closer together than 1 minute can be combined, i.e. just record the start of the first event and then the duration to the end of the last event (e.g. a period of restless sleep with someone rolling every 30 seconds for 5 minutes would be one entry, not 11 separate entries. Records of events in this video will be cross-checked with other sensors, and is the initial stage of a larger experiment, so if you record well there is a high probability many more such tasks.
