Ultrasound Used To Create Haptics That Can Be Touched and Felt

mrspoonsi writes "Bristol University used ultrasound focused to create 3d objects out of the thin air. The research, led by Dr Ben Long and colleagues Professor Sriram Subramanian, Sue Ann Seah and Tom Carter from the University of Bristol's Department of Computer Science, could change the way 3D shapes are used. The new technology could enable surgeons to explore a CT scan by enabling them to feel a disease, such as a tumor, using haptic feedback. The method uses ultrasound, which is focused onto hands above the device and that can be felt. By focussing complex patterns of ultrasound, the air disturbances can be seen as floating 3D shapes. Visually, the researchers have demonstrated the ultrasound patterns by directing the device at a thin layer of oil so that the depressions in the surface can be seen as spots when lit by a lamp. "In the future, people could feel holograms of objects that would not otherwise be touchable, such as feeling the differences between materials in a CT scan or understanding the shapes of artifacts in a museum."

      Except it's not a "hologram" in any sense, it's just another type of 3D technology.

      I hate the way Hollywood (and by extension, the video game industry) portrays holograms as light-shapes-floating-in-the-air. They're not; holograms are interference patterns recorded in a medium.

      Of course, you can call any 3D-projection technology a "hologram" if it makes you feel good, just like you can call a jetliner an "air locomotive." Doesn't make it one.

    Improving haptic feedback is a good idea, as the current attempts simply don't feel realistic. However, doctors feeling tumours? Why? That's a sophisticated audience; people who have trained, through qualifications and experience, to understand tumours through imaging. Yes, scrolling through a CT scan with a mouse wheel isn't realistic, but they've learnt to accommodate.

    On the other hand, the masses using touchscreen, that's an open market. Maybe it's a worthwhile one, maybe it's not. But that's the market to try. Otherwise it's like selling finger-friendly guitars. The professionals have adapted their fingers to the current steel--calluses and all. It's the beginners you want to target.

      Another issue with this technology being used for diagnosis is that a CT doesn't give tactile information about lesions within the body. It assesses tissue density (without contrast) and vascularity (with contrast). Feeling a certain degree of firmness of a palpated 'mass' would be completely arbitrary. Much more so than evidence based image interpretation techniques presently used by Radiologists.
