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, which speeds 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 ultra...
