This paper deals with the issue of human-computer identification. As the number of computing devices increase per person, the number of entries in wireless network lists increase. This makes it difficult for a person to select another computer or device to connect to in order to send information to that device. Traditionally, the name of the device is selected from a list of all visible devices on the network. As more and more devices are added to that list (with non-descriptive names much of the time), it becomes hard for humans to select the correct device to connect to. This trend contrasts with the increasing ease of computers to automatically enter, exit, and identify previously connected computers and devices. A solution to the human-computer identification problem is pointing. The device which the user wants to connect to is simply pointed at, and the computer can identify the target device and connect. This paper presents a device, called the gesturePen which sends an IR signal to tags installed on the target devices. By pointing the pen at the device, the device ID can be acquired and easily connected.
The paper illustrates some similar point-to-identify solutions, and points out that all others use a system which constantly broadcasts the device ids, which can still overwhelm the user. The gesturePen system tags "are only activated when ‘pinged’ by the gesturePen."
