Immerse the world on Bing, Google and Foursquare

One of the problems facing mappers is the abundance of locations to map.  My idea will aid in this using crowd sourcing.  If one takes a 360 degree video of a location from 2 or more spots, you should be able to build up a 3D visualization of the area. So in a store for example you go to 3 corners or up and down the isles and take a video on your iPhone or android or windows phone. Then you submit the video in to Bing who uses a Photosynth like technique to "build" the 3d map. You tag the map with its gps location. As more people do this we will be able to build up 3D virtualizations of huge amounts of areas. Where foursquare fits in with this is to add the social location aspect to it. You can encourage people to submit these videos by maybe creating new categories in foursquare like Chief Videographer for the person submitting the most videos etc...

I heart Apple

This was an idea that I had a while ago but was reminded by a posting today in Engadget (Pity I didn't patent this first)
Essentially today people use a device called a holder meter to monitor their heart rhythms. This is a portable device that you wear and it records your heart rate. The device I personally used had 3 leads and then a box to record the readings and then you transmitted the readings audibly over the phone once a day.  It would be much less invasive and easier if we had this iPhone app that has external leads to monitor your heart and then allowed you to electronically submit the readings online
The issues that I faced (why I didn't pursue this) is that you would need FCC approval for the device as its a medical related machine.

As you can see from the apple post, theirs is not aimed as medical device, but I believe it has great potential in that field.
