Problem: People who reference computers while doing other physical tasks (cooking, repairs, etc.) cannot read screens from a distance.
Concept: Web cam application which adjusts font size dependent upon user’s proximity.
Details: I like to cook for myself, but I refuse to buy cookbooks when there’s a wealth of recipes already online. The great thing about this is that I can use my laptop, which I can even position at any angle I want (in other words, no need for anything to prop a book up). The problem I find is that the text is never large enough to read at a distance. To address this, a Flash application would utilize a basic motion tracking system through the user’s web cam to approximate the users proximity to the screen. As the user moves away from the screen, Flash would then send commands to a Javascript function that would gradually increase the web page’s rendered font size.
To take things one step further, the application could also be given simple motion detection logic: if the user moves their arm upwards (i.e., the webcam tracks movement from the bottom of the video towards the top of the video), the page would scroll down and vice versa.
