Fujitsu's ring lets you write in the air with your fingertip
Head-mounted displays are frequently supposed to keep your hands free, but they only sometimes live up to that promise. You can't really dictate a message in a noisy warehouse, can you? If Fujitsu gets its way, you won't have to. It just built a smart ring that not only allows for motion control (something we've seen before), but in-air handwriting. All you do is trace letters with your fingertip, and the motion sensor translates those scribbles into usable characters -- supremely helpful if you need to send a quick reply when you don't have access to a keyboard. There's an NFC tag reader in the ring, too, so you can get instructions for working on a device just by tapping it.
Fujitsu touch interface detects fingers on real objects, adds digital details to print
Bringing touch interfaces to real-world objects often involves putting hardware either inside the item or in front of it, neither of which is especially natural. Fujitsu has developed a control system that could eliminate those obstructions and bring digital interaction to many surfaces, even to old-fashioned paper. Its multi-camera approach can distinguish between objects on a table and the exact positions of a user's fingers, right down to fingertip outlines; it's accurate enough to scan text from a book as you drag your finger along the page. The system really comes alive, however, when its projector is involved. Besides providing visual feedback, the image overlay allows for both control of purely digital objects and interfaces tailored to real-world items. The company imagines brochures or maps that pop up extra details, among numerous other examples. While we wonder how long the technology will remain useful when there's an ongoing push to go paperless, Fujitsu sees enough practicality that it's anticipating a product in its fiscal 2014. That doesn't leave long until we can get a very literal hands-on.
SanDisk makes 128-gigabit flash chip, crams three bits per cell, takes afternoon off
SanDisk has developed a chip that earns it membership in the exclusive 128-gigabit club. Not content with simply matching the Micron / Intel effort, SanDisk and its partner Toshiba claim their new memory uses 19- rather than 20-nanometer cells in the production process. Shrinking the size is one thing, but SanDisk's new chips also use its X3 / three-bit technology. Most memory stores just two bits per cell; cramming in another means fewer cells, less silicon, more savings, cheaper memory, happier geeks. Analyst Jim Handy estimates that the price per gigabyte for the tri-bit breed of flash could be as low as 28 cents, compared to 35 for the Micron / Intel equivalent. Full details in the not-so-compact press release after the break.
Intel, Micron unveil first 128-gigabit flash chip, provide double the data density
Realign the data and the previous 32- and 64-gigabit roadblocks to flash storage disappear. Today, Intel and Micron announced the first 128-gigabit NAND flash chip. The chip, which was created through the companies' joint IM Flash Technologies venture, is smaller than a fingertip, created through a 20 nanometer manufacturing process and is capable of 333 megatransfers per second with the option of stacking as many as eight chips on top of each other. What makes the new NAND unique is its planar structure that allows individual memory cells to scale much smaller than before. When combined with a Hi-K/metal gate combo to keep the power leaks to a minimum, presto, you've got flash memory denser than your mother-in-law's fruitcake. Mass production of the 128Gb chips isn't due until the first half of 2012, but you can get a more in-depth intro to the future of flash right now in the PR below.
Touch pad prototype works without movement, makes fingertips feel like they're sliding (video)
This comes from the same touchy-feely Kajimoto lab in Japan that brought us the tactile kiss transmission device and we totally see where they're going with it: maximum sensation, minimum effort. You only have to exert the gentlest of pressures on this prototype touch pad and it zaps your fingertip with little electrical signals, mimicking the feeling of sliding your finger over a surface. We imagine it's a bit like the little red pointing stick in the middle of a Lenovo ThinkPad keyboard, for example, but with the addition of "position-dependent data input" to create the illusion that your finger is actually touching different areas of the screen. For now though, if you don't mind stretching a finger to your old-stylee mouse or trackpad, then check out the video after the break.
Work your Wiimote with your fingertips
An ingenious little hack enables anyone with a Wii, a powerful infrared emitter, and some reflective tape to control their Wii with their fingertips, as demonstrated in the creator's YouTube video. The "hack" involves sticking the reflective pads on your fingertips, and placing a Wiimote close to an infrared emitter, with the result being that the Wiimote thinks it's moving when in fact your fingers are. The hack won't work very well with your Wii -- can't press dem buttons! -- so it's limited to gimmicky Minority Report-style demos on your PC. Besides, isn't the whole point of couch potato gaming that you don't have to lift a finger?[Via Hackaday]
