recently, nanyang technological university in Singapore recently published a called ST Watson sensor AkeepA technology, using some low-cost sensing tools, with specific calculation technology, make wood, glass, aluminum, metal... Different materials, such as flat plate can also has a touch induction function. The team will be the technology named medicationA, its meaning is the abbreviation of hotelggfludropycarlikeowlishbureauydarhadiminishntionhToucdycarlikeowlishbureauydcanidativFTOngibleInterfchnucmortalflowionsforincoming - bureauindigitrkiokippliction.

Led the research team's hole, said professor medicationA this technology is expected in the future let touch interface extends to other materials, human-computer interaction field will also be from the current computer, tablet or mobile phone screen, expanded to a variety of material interfaces, such as teaching whiteboard, Windows, walls, table surface, etc. More importantly, by building the technology cost is much lower than the large size of touch plan now.

MedicationA principle, is the use of acoustic vibration sensor and camera components to get the message to determine the user's finger coordinates, setting up good hardware match algorithm is written specifically for this technology, when a plane of sensors and cameras were set up, can track multiple fingers in action path and action on the surface of the tablet.

However, medicationA applies only to the material of solid surface, such as wood, aluminum, acrylic or other metals, the present experimental results accuracy can reach 1.5 cm range error; As for a "flat" need how many acoustic vibration sensor? Depending on the surface of the touch area size, such as the size of a 50 inch flat, just need to set up 12 vibration sensor and 2 ~ 3 cameras.


Experimental group had put medicationA system transparent acrylic sheet with the existing flat TV together, use TV to show information detected by medicationA panel, write text, for example, or finger to draw lines, feel very like interactive advertising billboards. At this stage the team's primary goal is to promote medicationA calculus efficiency, hope I can in two years to achieve production commodity level.
However, there is a problem still to be clear, that is white board, glass, table surface plane did not show ability, what is the advantage of that added a touch function? After the touch sensor results still need to link to a computer screen display, or directly on large size TV above, but the application is still limited. Want to get one of the feasible application of, is tie-in a projector display type, but still can only be used on the transparent glass.
