iPod touch FaceTime hands-on:
iPod touch
The gap between the iPod touch and the iPhone continues to decrease, with this fourth-gen version of the Apple PMP gaining the headline functionality of its fourth-gen cellular sibling. Amazingly it’s even thinner than the waifish model it replaces, down to just 0.28-inches and 3.56 oz, still with a premium-feel stainless steel back plate and black glass fascia. Controls are as before, a home button under the display, sleep/wake on top and volume on the left hand side; the Dock Connector and 3.5mm headphone socket are on the bottom.
iPod touch FaceTime hands-on:
Most eye-catching is the 3.5-inch Retina Display, carried over from the iPhone 4 and just as impressive on the new iPod touch. At 960 x 640 resolution – totaling a luxurious 326 pixels per inch – it’s everything Apple’s hyperbole could say about it. Color-rich, with fonts as smooth as print and bags of contrast, it’s tough not to fall in love at first glance. Multitouch support is obviously present, as is WiFi b/g/n (802.11n using the 2.4GHz band only) and Bluetooth 2.1+EDR: no GPS, though the touch can triangulate position using known WiFi networks nearby. Finally, gamers should be excited by the new three-axis gyroscope, which offers vastly more accurate positioning information.
Once you’ve gotten past the Retina Display, you might notice the small lens peering out from where an iPhone 4′s earpiece would be. The new iPod touch gets two cameras: one, a front-facing VGA camera for FaceTime calls, and a higher-resolution camera on the back capable of 720p 30fps video recording or 960 x 720 stills. The FaceTime support is something that’s been rumored since the service was first announced: offering, as you’d expect, not only touch-to-touch video calls but touch-to-iPhone 4 calls, it opens up Apple’s system to a segment unwilling or unable to sign up for a cellular contract, yet who want to get in on the fun. Initiating FaceTime calls remains straightforward, tapping the contact and then flicking between the two camera views when connected by touching the display.

Hands-on: Miniature LCOS Laser Picoprojector Is As Big As A Matchbox
This amazing little projector, OEMed by XDM, a part of Explay in Japan, is truly something to behold. Smaller than a matchbox – it’s about an inch on each side – it pumps out an unspeckled 14 lumens image in full color at about 800 pixels on the top side. It small enough to fit in the upper corner of almost any phone and the aperture is so tiny it’s almost unnoticeable. And guess what? XDM is making it smaller.
The rig they showed me was fairly bulky but they’re currently working on an ASIC controller chip that will reduce all of the circuitry to a few square centimeters. The are also working on a 20 lumens model as well as a smaller model that is half the size of the current system.
XDM will OEM these parts and they currently have a number of folks interested. Expect picoprojectors to really take off in the next few months as these hit market, especially considering you can stick these things into almost any device including cellphones, cameras, and laptops.
Explay starts shipping laser pico-projector modules to customers, expects products in Feb 2011
Laser Projector camera Projector phone
Explay says that their laser pico-projector module has started shipping to customers. They expect product that include the projector (mainly phones and cameras) to start appearing on February 2011. The projector supports WVGA (854x480), 14 lumens and up to 70" projections. The total volume is 6.3cc, and the height is 7mm (a bit larger than Microvision's PicoP which is 5cc). The module consumes 1.8W (1.3w for the light-engine and 0.5w for the control circuit).
Explay is also working on two next-gen products, that will be available towards the end of 2011. The first will be pretty much the same module, but with 20 lumens. The second will support WXGA (1366x768) at 25 lumens.
