SCIENCE & TECHNOLOGY: INNOVATION: Kaviraj Prithvi’s Team Wins ‘Best Social Impact Business Idea’ for ‘Tactall-Braille Printer’ at Startup Fest ‘SmartIDEAthon 2022’

A portable and inexpensive Braille printer, an invention by a Karnataka student, won the Best Social Impact Business Idea at the SmartIDEAthon 2022, a nationwide pitch fest organised by Startup India in collaboration with several universities.

Prithvi Systems and Innovations founder and chief invertor Kaviraj Prithvi’s team was one of the 1,200 shortlisted for the fest and has been working towards inventing assistive technolog

The Tactall, a mouse-sized portable printer, allows for easy printing in Braille and is relatively inexpensive, according to Kaviraj.

“Braille printers print in standard dimensions and they are often very large, expensive and standalone, averaging to about $2000 to $3000. We wanted to make it more accessible for people to print in Braille, especially as this was a common problem which I found out when I had visited a school for the blind,” Kaviraj told TNIE. While the printer is in its prototype stage, Kaviraj, who is also pursuing engineering physics at II T Guwahati, and his team of 15 members, are also working towards inventing other types of assistive tech.

“All of our inventions have assistive angle to them. When I was younger, I wanted to start a startup and I felt that everything that I invented should have a social angle and must help people,” he said.

Apart from the printer, Kaviraj is also working towards building a non-invasive way to monitor blood pressure, as well as a patented rotor control system and a suspension system for bumps. “The suspension system is being designed specifically for wheelchairs and other support vehicles, but it can also be used generally. The rotor system is specifically for helicopters, to allow for easier rescue operations and to lessen turbulence while transporting patients,” he said.

INDIAN RECORDS: KARNATAKA: HEALTH & MEDICAL SCIENCES / SCIENCE & TECHNOLOGY: Researchers at Indian Institute of Science (IISc) Develop Algorithm called (ReAl – LiFE) to Study Connectivity in Brain

Researchers at Indian Institute of Science (IISc.) have developed a new graphic processing unit (GPU) based machine learning algorithm called Regularised, Accelerated, Linear Fascicle Evaluation (ReAl – LiFE), which will help to obtain a better understanding and in the prediction of connectivity between different regions of human brain.

This algorithm can help analyse extensive data generated from diffusion Magnetic Resonance Imaging (dMRI) scans which helps scientists study the connectivity in the brain at a speed, which is 150 times higher than a regular desktop computer or existing state-of-the-art algorithms. The study has been published in the journal Nature Computational Science.

“Even though it is difficult to pinpoint the connectomes, we are trying to infer information highway network by looking at traffic flow patterns (if molecules are like cars). We look at the movement of water molecules in the brain and we try to infer where the wires are. The water molecules have to travel along the length of the cables (axons), which have connected various parts of the brain. By measuring these lengths of water molecules, we are able to infer which areas are connected,” explained Devarajan Sridharan, Associate Professor at the Centre for Neuroscience (CNS), IISc., and corresponding author of the study.
