Abstract: Paper-based playback of media can be performed by electronically recording handwritten notes including pen strokes using a digital pen on a position-coded paper. A plurality of bounding areas is identified, e.g. by generating bounding areas around the pen strokes as they are developed. Each bounding box is provided with a time stamp which indexes a media file, which was recorded simultaneously with the handwritten notes. By placing the digital pen close to a handwritten note on the paper, the part of the media that was recorded when the specific note was written can be recalled. More specifically, the bounding box corresponding to the position of the digital pen is identified and the associated time stamp is used to find the media to recall. This paper-based playback of media can be performed in e.g. a stand-alone device or by a combination of a digital pen and a mobile phone.

Abstract: A system and method of identifying a source of a software distribution between portable computer systems. A user of a first hand held computer may transfer software, for example operating system extensions, application programs and data sets etc. to a second hand held computer. This transfer may occur wirelessly. An identification token which may identify the source of the software distribution may also be transferred, and further transferred from the second hand held computer to an “e commerce” web site in an automatic manner. In this novel manner, the sources of software distribution of respective files among many hand held computer users, may be identified to the website. This may result in wider distribution of both information about available software and the software itself, and a multi-order multiplication of economic effects in the hand held industry, while overcoming many deficiencies in the prior art of software distribution for hand held computers.
