Engineers at Facebook’s Connectivity Lab have developed a large laser detector that could help deliver Internet to new areas by opening “airwaves to new high-speed data communications systems that don’t require dedicated spectrum or licenses,” reports PC World. Reaching new regions typically involves cost-efficient wireless networks, which also require radio spectrum and often have speed limitations. Instead, engineers are looking into “sending data from point-to-point over laser beams” that would not involve “any special spectrum or permission, and multiple systems can work in the same area without interfering with each other.” Continue reading Facebook Considers Laser Tech to Deliver High-Speed Internet

A year after going on record that they would open up their tracking systems to third party developers, neither Oculus nor Valve have done so. So called ‘6DOF’ (degrees of freedom) tracking allows for head and body tracking, as well as mapping of physical objects like handheld objects and furniture, into the virtual world. Oculus’ Constellation tracking system uses a collection of IR-LEDs tracked by an external camera. Meanwhile, Valve/HTC’s Lighthouse tracking system uses photodiodes that track lasers from base stations. Continue reading Oculus and Valve Have Yet to Open Tracking to Third Parties
