Their 'Sparsh' allows multiple touch

AHMEDABAD: Are you getting bored to use touch screens at kiosks or ATMs with just one finger? Does it feel helpless that you can play online games with a single touch only? 

Well, four students of Maharaja Sayajirao University (MSU) faculty of technology, worked out a technology to make one's interaction with computer more intuitive. 

The quartet - Deepal Shah, Jaimin Shah, Jaydeep Marakana and Kaushik Patel - have made a low-cost multi-touch interaction system named Sparsh, as a part of their final year project. 

Some Bangalore-based companies have already approached them to help them commercialise this technology. 

Based on the frustrated total internal reflection (FTIR) concept, unlike the conventional touch screens, which have restriction of handling only one touch at a given time, their system allows multiple touches. 

"We had seen people standing for long at ATMs and different public-utility kiosks machines, as they can access the machine only with one touch. So we decided to design a machine that allows multiple touches at the same time," says Jaimin, who is going to New York to study this technology in detail. 

The group went on to make real-life application working model, which can be used commercially. The cost of their entire system comes down to Rs 40,000. 

As the technology is yet popular in India, the students referred to a paper presented by a New York-based professor. 

"We had to do a lot of research and finding hardware like hi-end infra-red LEDs (light emitting diodes) was also not easy. Also, as we had only four months to prepare the entire system, we used to attend the college lectures in day and work on the project in night," says Deepal. 

This group has even bagged first prizes at two national tech festivals for their innovation. 

They recovered the entire project cost from the prizes we won at the MSU festival Footprints '08 and Imaze '08 organized by Sardar Patel University, Vallabh Vidyanagar.
