At DSE 2012 (Digital Signage Expo) held in Las Vegas (March 7th to 8th, 2012), the leading multi-touch solutions provider ZaagTech debuted infrared multi-touch overlays that are waterproof and dustproof for the first time, solving the long-existing stability challenge for infrared technology and making it possible for infrared multi-touch to be applied in a much wider universe. The innovation was showcased as a component of a multi-touch table that is only 2 inch in thickness and supports up to 40 true touch points. Exhibitors from ZaagTech impressively demonstrated in the above video clip how resilient the multi-touch overlay performs by pouring drinks on to the screen. As it shows the touch panel recognizes multi touch points precisely as usual even after cups of liquid spill. "Infrared overlays are widely chosen for multi-touch kiosks, digital signage, tables and walls because of reliability and cost effectiveness," explained Olivia Yin, Co-founder and COO at ZaagTech, "but the challenge for the solution is the stability issue: the sophisticated hardware structure and algorithm are sensitive to disturbing obstacles. By introducing a product that performs well in much less perfect environment, ZaagTech solved this long-lasting problem for the first time and we are confident to bring a blast to the industry, eventually making multi-touch interaction applicable and realizable in more occasions - now a little drink spill will no longer stop you from playing games on your multi-touch bar table." Besides full range of infrared multi-touch overlays, ZaagTech also presented a 3D curved multi-touch wall that is 3.8 meters long, which demonstrates the firm's ability in accomplishing customized projects. As claimed by ZaagTech, such customized multi-touch solutions are powered by their proprietary HSIR+ (Hybrid Scattered Infrared Plus) technology, another revolutionary innovation for the multi-touch industry. DSE is the world's largest international trade show dedicated to digital signage, interactive technologies and out-of-home networks.
