Embodiment Construction
[0034]Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to one preferred embodiment. On the contrary, it is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the described embodiments as defined by the appended claims.
[0035] As mentioned earlier, device awareness (or device-to-device awareness) is a prerequisite for device-to-device interaction. Device-to-device location awareness can also be useful, as it can enable an electronic device to be contextually associated with its owner (e.g., when using a smartphone to communicate privately around a conference room table, when a motor vehicle on a highway when navigating between devices, when communicating with smart home appliances in the home or office, etc.), and can enable certain features in interacti...

The invention is entitled "Device Awareness in Line-of-Sight Optical Communication Systems". The present invention discloses techniques by which electronic devices including line-of-sight optical communication systems can optically sense other electronic devices and perform optical communication handshaking with other devices. When an electronic device determines during performing an optical communication handshake that it is pointing at the electronic device with which it is performing an optical communication handshake (or that another electronic device is within the electronic device's field of view), the electronic device may use a motion sensor to record its gesture. The recorded device pose, combined with optical communication and motion sensor data, can also be used to map the location of another device and enable the user of the electronic device to pan away and disrupt the optical communication with another device, then easily return back to enable continued A recorded pose for optical communication with another device.
Description
[0001] Cross References to Related Applications [0002] This application is a non-provisional of U.S. Provisional Patent Application No. 62 / 678,191, filed May 30, 2018 and entitled "Device Awareness in Line-Of-Sight Optical Communication Systems" application, and is claimed under 35 U.S.C. 119(e), the contents of which are incorporated herein by reference as if fully disclosed herein. technical field [0003] The described embodiments generally relate to line-of-sight optical communication systems. More specifically, the described embodiments relate to device awareness in line-of-sight optical communication systems, and to electronic devices that use optical communication systems in combination with motion sensors to provide device-to-device position awareness. Background technique [0004] With the use of mobile electronic devices such as smartphones, tablet computers, and smart wearables becoming an integral part of modern life, device-to-device interactions are expected...
