    This isn't the first time you've heard of EPOS or XTR, but it's been quite some time since we've checked in with either of the outfits. So, imagine our surprise as we stumbled on new developments from each company as we perused the Texas Instruments booth at MWC. In the case of EPOS, we're shown a stylus that, in addition to offering traditional physical touch input, also allows users to interact with a device via ultrasound. The system is built upon TI's OMAP4 platform and requires that four microphones be placed at the corners of the screen. In this demonstration, we're shown how users can manipulate objects on a 3D plane via the Z-axis by pulling the pen away from the display. Next, we're shown a new application for the touchless gesturing system that XTR first debuted back in 2010. In this scenario, it's demonstrated how tablet owners could use the front-facing camera (at merely QVGA resolution) to flip through pages of a cookbook without worry of getting ingredients on the device. The concept software was developed by a French outfit known as Stonetrip, and also allows users to zoom and pan through the pages. You'll find demonstrations of each technology in a video after the break.

  • Qualcomm takes sci-fi one step closer to reality at Computex 2011 (video)

    While flying cars are still a pipe dream, other technologies are quickly transitioning from the stuff of sci-fi movies into the very tangible realm of reality. This was definitely the case at the Qualcomm booth here at Computex where we got to experience two interesting new technologies -- zero shutter lag and the ultrasonic pen. What if when you pressed the shutter button on your phone the camera captured 2 frames before, one frame during, and 2 frames after that instant? That's the idea behind Scalado's zero shutter lag and Rewind, which speed up the process of taking pictures on a phone by letting the camera continuously sample images and allowing the user to create a composite shot from the content available in up to 5 frames.Also on display was Qualcomm's ultrasonic pen that we already played with at MWC. By using an ultrasonic transducer attached to a pen and a phone with 3 microphones (like the MSM8660 Mobile Development Platform), the ultrasonic signal can be triangulated to determine the location of the pen. Once calibrated, the phone is able to accurately capture handwriting either on the screen itself or on a standard sheet of paper up to 30cm away. We noticed that accuracy and distance appear to have improved since February -- at this pace, perhaps we'll all have flying cars soon after all?

  • Qualcomm's ultrasonic pen demo transcribes from paper to device (video)

    LG's Netflix-lovin' Revolution wasn't the only standout demonstration at Qualcomm's MWC booth -- the company also cut out a bit of space to showcase a wild new ultrasonic pen that's able to transcribe writing on paper directly into one's phone, tablet or laptop. The gist of it is simple: the pen can be equipped with an actual ink pen or a simple nub, and there's a battery-powered transceiver inside. Using standard, off-the-shelf microphones on a mobile device, your future phone or tablet could pick up vibrations from the pen with a radius of around 30 centimeters. Underlying Epos software is used to convert vibration and coordinate information into text, and from there, any 'ole text app can be used to field the results. We were even shown a brief demo of a prototype language translation app that enabled the demonstrator to write a sentence on paper beside the phone, and have the phone itself take in the English phrase, convert it to text, and then translate into a foreign tongue. It's a fairly impressive feat, and there's some pretty obvious usage case scenarios here -- this could easily reinvent the art of note taking in class, where those who prefer to jot down reminders on paper will be able to log those same bullet points on their laptop as they scribble. Vid's after the break, per usual. %Gallery-116712%
