Problems solved by technology

These "unwanted" behaviors mean possible privacy issues for the user (becoming visible to others, preferably invisible), which means that all types of of devices are submerged because they are within the coverage area of ​​the sensing device

Embodiment 1

[0023] see now Figure 4 Assume that the Bluetooth ad hoc network 400 includes the following devices: a TV 401 , a personal digital assistant (PDA) 402 that can take pictures, and a portable hard disk 403 . As long as the devices are within 10 meters of each other, they can communicate. To create a "sensing area", short-range sensing technology in the form of a tag (reader) is added to the device. Coded labels are what enable the device to be uniquely identified. Tag readers can only read these tags if they are within a short distance (~10cm) of each other. In order to display the picture saved by the PDA 402 on the TV screen 401, the user only needs to place the PDA 402 close to the TV 401 so that the picture is displayed on the TV 401. Likewise, in order to display the audio / video content of the portable hard disk 403 on the TV 401, the portable hard disk 403 may be placed close to the TV 401.

Embodiment 2

[0025] see now Figure 5 Assume that the 802.11 network 500 includes the following devices: a TV 501 with a tag reader and two portable MP3 players 502.1 502.2 each with tags. If both audio devices 502.1 502.2 are within the sensing area of ​​the TV 501, the TV's UI automatically generates a playlist combining all their music.

Embodiment 3

[0027] see now Image 6 Assume that the Bluetooth ad hoc network 600 includes the following devices: a printer 601 with a tag reader, and a PDA 602 with a tag capable of taking pictures. By bringing the phone 602 near the printer 601, the PDA 602 senses the printer 601. As a result, phone 602 suggests printing the currently "active" file (eg, the selected picture). The user simply accepts and the picture is printed on the printer 601 .

Abstract

A method and system are provided for electronic devices (10i, 30i, 40i, 50i, 60i) in a home network to have a sense area (310) for detecting one another. This sense area (310) eliminates participation of outsiders in a home network (100, 300, 400, 500, 600). To allow sense areas that are particular to a given device type, in an alternative embodiment, the size and shape of the particularized (110) sense areas can be made to depend on device characteristics, such as portability, and the sensitivity of the device can be adjusted to meet device requirements. Devices (10i, 30i, 40i, 50i, 60i) are placed near to one another to form a network and if no device is sensed communication and display of one another's user interfaces is optionally disabled so others cannot see the device, e.g., when the device (10i, 30i, 40i, 50i, 60i) is removed from its home network (100, 300, 400, 500, 600).

Description

technical field [0001] The present invention relates to a sensearea for a home intranet of electronic devices. Background technique [0002] All common wireless standards for home intranets (802.11x, Bluetooth) implement a device discovery mechanism to identify all devices within the network coverage area to communicate. Typically, these coverage areas are from ~10 meters (eg, raw Bluetooth power levels) to 30 meters (eg, 802.11a / b / g), but are foreseen in the near future from ~10 cm (eg, short Bluetooth power level) to ~100 meters (eg, long Bluetooth power level). Thus, a device can observe all devices within its range (read coverage area). In urban environments, this can lead to "unwanted" behavior, such as devices being recognized by nearby or just passing recognition devices. These "unwanted" behaviors imply possible privacy issues for the user (becoming visible to others, and preferably invisible), meaning all types of of devices are submerged because they are within...
