A Gest Wearable Means for Gesture Control

A Gest Wearable Means for Gesture Control

A startup named Apotact Labs takes to Kickstarter to propose a wearable take on gesture-based control-- the Gest (pronounced "jest"), a "one size fits all" soft glove fitted with flex and motion controls.

Somewhat reminiscent of a stripped down version of motion control gloves such as the Nintendo Power Glove, the Gest consists of 4 small bands attached to an adjustable black strap. The bands and strap carry accelerometers, gyroscopes and magnetometers, and pair with PCs or mobile devices via Bluetooth to transmit the relative positions of the fingers wearing the device.

The Gest is designed to be as light and simple as possible, and the makers claim the battery provides up to a "full day of work" on a single charge. It does not capture the exact way the hand moves, but supposedly allows for fairly complex gestures wearers can assign to specific controls.

How to Use Wifi to See Through Walls

How to Use Wifi to See Through Walls

Researchers at the MIT Computer Science and Artificial Intelligence Lab present a non-networking use for wifi-- as a means to see through walls, essentially making an X-ray vision of sorts.

Dubbed RF-Capture, the technology uses variations in wifi signals to recognise human silhouettes from behind walls. To do so it first transmits wifi signals before analysing reflections in the signals to piece together a human form. In other words, it is a little bit like a radar. It requires no wearable sensors and transmission power is "10000 times lower" than standard mobile phone signals.

The researchers say the technology (or rather, the algorithm behind it) is accurate enough to know who the person behind a wall is, determine how he or she is moving and even trace a person's handwriting in air, all by piecing together a silhouette from the reflected wifi signals.

Samsung Gear VR Reaches Consumer Version

Samsung Gear VR Reaches Consumer Version

Samsung presents the consumer version of the Gear VR, the smartphone-powered virtual reality headset developed in collaboration with Rift maker Oculus.

Improvements on the previous "Innovator Edition" headset include lighter construction (by 22%, Samsung says), foam cushioning for additional comfort and an improved touchpad controller on the temple.

The headset also fits more Samsung smartphones-- namely the Galaxy Note 5, Galaxy S6 Edge+, S6 and S6 Edge-- through the addition of sliding clamps allowing users to insert larger phones. The smartphones should provide a similar VR experience, since all have 2560x1440 resolution displays.

How to Bring Game Cartridges to Smartphones

How to Bring Game Cartridges to Smartphones

A Japanese startup named Beatrobo presents an interesting way to bring the game cartridge to the smartphone era-- the Pico Casette, a tiny cartridge one plugs into device headphone jacks to unlock games.

Unlike its larger, retro brethren the Pico Cassette does not actually store games. Instead it transmits an inaudible tone to authenticate games on a companion app. In addition it also connects with Beatrobo servers to allow users to play and save progress on multiple devices.

The technology behind the Pico Cassette is called PlugAir, and is already used to sell physical music and video content at Lawson HMV stores in Japan.

Kickstarting Real-Life Wizard Battles

Harry Potter fans might soon get a means to hold real-life wizard duels against friends and foes-- the Maguss Wand, a wand powered not by magic but by a receiver badge and a companion smartphone app.

The concept behind the Maguss Wand is actually fairly simple. The wand carries motion sensors and an IR LED, while the badge holds an IR receiver. Users cast "spells" by waving the wand in various patterns picked up by the badge. In turn the badge communicates with the mobile app to keep track of duels and even provide sound effects.

iPod Touch Gets A8-Powered Update

Apple announces a long-awaited refresh of the iPod media player family-- the first since 2012-- featuring an upgraded iPod Touch complete with iPhone 6 chip and new colours for the Nano and Shuffle.

The latest iPod Touch features a 64-bit A8 processor allowing for better performance, especially when it comes to games. It also carries the M8 motion coprocessor for fitness, step and elevation tracker, and the same 8MP camera as the iPhone 6.

The Next Oculus Rival: StarVR

Swedish games developer Starbreeze (Payday 2, Syndicate) is the next unlikely company to take on the potentially lucrative world virtual reality as it unveils the StarVR headset at E3 2015.

The result of the acquisition of French hardware startup InfinitEye, the StarVR promises to be superior to the likes of the Oculus Rift through a super-wide field of view-- 210-degree, more than double the 100-degrees offered by the rival headset.

Further tech details include two 5.5-inch quad HD (2560x1440) displays within a fresnel lens design and head tracking through fiducial markers and a combination of gyroscopes, accelerometers and magnetometers.

Oculus Details Rift Final Version, Controllers

Oculus Details Rift Final Version, Controllers

Facebook-owned virtual reality headset maker Oculus reveals the final consumer version of the Rift at a press event just ahead of E3 2015, together with a companion input device dubbed the Oculus Touch.

The final version of the Rift headset is, ultimately, a refined take on earlier prototypes, if one with improved ergonomics. It features two low-persistence AMOLED displays, an IR LED constellation system for 360-degree head tracking, built-in VR audio system and "high quality" internal microphone.

Users can control VR games through a regular gamepad, but Oculus suggests an own control alternative-- the Touch, a pair of controllers (think the non-remote part of the Wii controller) featuring an analog thumbstick, two buttons and an analog trigger.

The Eye-Tracking VR Headset

The Eye-Tracking VR Headset

A Tokyo-based startup named Fove enters the virtual reality (VR) fray with a headset the company claims ditches the need for handheld controllers through the use of eye-tracking technology.

The headset, also dubbed Fove, promises superior interaction with virtual worlds, since the human eye is actually fast, accurate and very responsive. Said tracking is done through the combination of a pair of infrared cameras and an appropriate algorithm.

The result according to the company is games interacting with the one's gaze, such as virtual characters meeting the player in the eye or simply aiming and shooting through the power of a stare. In addition the system handles "foveated rendering," a process allowing graphics engines to concentrate processing power on the image the player is looking at.
