摘要:
Embodiments of the invention address how trilateration processes are affected by physical placement and sub-optimal selection of peer devices (PDs) used to obtain a location of a mobile computing device. Embodiments of the invention describe processes for selecting nearest PDs over further PDs, as received signal strength indicator (RSSI) measurements are more reliable— i.e., said "nearest PDs" provide more accurate distance measurements while improving the probability of finding more intersection points. Embodiments of the invention further describe selecting a physical spread of PDs to help increase the number of intersection points while helping distinction/resolution of the location of the mobile device in both the 'x' (longitude) and the 'y' (latitude) directions. Embodiments of the invention further enhance trilateration processes by utilizing dampening values for calculated location poll data.

Embodiments of the invention selectively utilize abnormal location poll data when executing location determination processes. Embodiments of the invention further enhance trilateration processes by utilizing dampening values for calculated location poll data.
摘要:
Technologies for audiovisual communication include an audiovisual server and a number of audiovisual client devices, including a presenter device and a number of audience devices. Each audience device captures an audiovisual stream and transmits the audiovisual stream to the audiovisual server. Each audience device also captures sensor input data such as eye tracking data or facial expression data and transmits abstracted sensor input data to the audiovisual server. The abstracted sensor input data may be based on the captured audiovisual stream. The audiovisual server determines an interestingness rating associated with each audience device based on the sensor input data, and selects one or more audiovisual streams based on the interestingness ratings. The audiovisual server transmits the selected audiovisual streams to the presenter device. The audiovisual server may update the interestingness rating algorithm based on feedback from the presenter device or the audience devices. Other embodiments are described and claimed.

An example system that allows a camera enabled application, such as an augmented reality application, to run in a protected area may include a first device including a camera, the camera including a secure mode of operation and a display, an image processing module configured to convert image data from the camera to encoded data when the camera is in the secure mode and protect image data stored in the system, an encryption module configured to encrypt encoded data from the image processing module, and a protected audiovisual path mechanism configured to securely send augmented encoded data to the display.
