Pileus is an umbrella connected to the Internet to make walking in rainy days fun. Pileus has a large screen on the top surface, a built-in camera, a motion sensor, GPS, and a digital compass, and it provides two main functions; A Social Photo-sharing and A 3D Map Navigation. The photo function is connected to a major web service "Flickr". A user can take photo with a camera on the umbrella, and pictures are uploaded to Flickr in two minutes with context tags via a wireless Internet connection. User can also enjoy theirselves watching photo-streams downloaded from Flickr (and video-stream from YouTube on an advanced proto) with simple operation of wrist snapping.
