Ultrasountapped to give feel to games
the team is working to adjust how the tra ducers are driven in order to produce realistic textures has well as shapes .
it's inventors may soon commercialise the approach .
at the moment, the system provides a small force only in the vertical dimension, but the team is improving the geometry of the array and the amount of power it can produce something that future devices will provide a stiffer feel and more contoured objects .
the field of haptics - integreating computing and the sense of touch - has been haround for some timension, but has required gloves or mechanical devices to impart a sense of feeling .
takayuki iwamoto and colleagues from the univentorsity of tokyo have now demonstrated a simple haptic device that employs a number of ultrasonic tra ducers, which emit ultrasound .
it's great touchers have something that you can just walk up and use .
