Perceptive Presence Lamp "virtually connected two spaces (e.g. offices, homes, etc.) and conveyed a sense of the activities in the remote location. This could be used to better manage collaborations or as an aging-in-place tool. The lamp in the first location would be off if no one was present in the second location. It would turn green if one person was present or red if multiple people were present or conversation was detected. A user could get the attention of the person in the other location by staring at the lamp for several seconds, in which case both lamps would flash blue, similar to staring at an officemate for a few seconds to get their attention. If the remote user then stared at their lamp, an audio connection would be opened between the spaces."
