One of the goals of pervasive computing is to knit computers, sensors, etc within the fabric of the building or environment. Yet one of the oldest means of communication in an office environment is through leaving a note on the door. However, there is always the concern that the note can be removed, or viewed by everyone.
BluNotes is a project that explores ways of leaving e-notes; electronic notes that can be displayed on the door. By targetting an e-note for a specific recipient, the message can be presented on a display when the recipient is nearby, and then hidden when the recipient leaves. It explores the use of situated displays, and identification of everyday ubiquitous devices, such as bluetooth enabled phones or PDAs.
