Although in the earliest stages of development, this virtual reality gaming rig already looks pretty intriguing. Engineered by clever kids at the University of Texas at Austin, it hot-wires an eye tracking camera to a motorised pico projector with the result that the player literally can't take their eyes off the screen. Wherever they look, that is where their view of the gaming world is projected. The rig makes most sense in a first-person shooter, although the students have also tried it in a flight simulator where the player uses their head to roll and pitch the aircraft. Yes, it looks rather similar to the Microvision PicoP laser projection gun we wielded at CES, but there's a key difference: the player does not need to hold anything or have anything attached to their body. This unencumbered Kinect-esque approach could potentially allow a greater sense of freedom -- except that, for it to work, the player is forced to sit directly in front of the eye tracker. Find a way to fix this, dear Longhorns, and you could be onto something. Video after the break.
Pentax's Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi. The new hotshoe-mounted O-GPS1 module fixes that oversight by recording latitude, longitude, altitude, Coordinated Universal Time and shooting angle. Everyday snappers might find an extra hotshoe attachment cumbersome, but astro-photography enthusiasts could well be enticed by the device's interesting "ASTROTRACER" function. This helps you take clearer photos of celestial bodies by using the in-built sensors to calculate a star's movement and then employing the camera's shake reduction system to compensate. Sounds clever, but be advised: this module is only for Pentax DSLRs -- and only for very specific models at that. You'll get full functionality with the K-5 and K-r cameras, and geotagging (no ASTROTRACER) with the 645D. Oh, and you'll need to make sure yo
