Now, an app to assist color blind college students behavior lab experiments
KOLKATA: Indian scientists have advanced a phone app that facilitates shade blind and visually impaired college students stumble on color modifications in a habitual lab experiment, thereby ensuring their active participation and independence.
The app, Titration ColorCam, is a leap forward within the ongoing attempt to broaden assistive mobile era to resource blind students in technology, era, engineering, and mathematics (STEM), said Subhajit Bandyopadhyay and Balraj B Rathod of the Indian Institute of Science Education and Research (IISER) Kolkata.

It affords a multi-sensory notion of shade trade discovered in a titration test, in which a solution of regarded awareness is used to determine the concentration of an unknown solution.
The layout and improvement of the app were usually focused on the issues confronted by means of coloration-blind college students in chemistry labs, Bandyopadhyay, of IISER-Kolkata’s Department of Chemical Sciences, instructed IANS.
“By following the application academic and laboratory education for coping with the apparatus, a color-blind scholar can carry out the experiment independently and with no trouble,” he stated.

It may be freely downloaded from the Google Play Store on Android devices with platform version 2.2 and up.
The utility makes use of the digital camera feature of a cellphone to capture and quantify the statistics worried in a color alternate at some stage in the titration test.
The app records and digitizes the color facts, and at the desired color trade responds with beep sounds and vibration pulses, which are generated through the smartphone.

The work has been documented in an era record of the Journal of Chemical Education in June.
For students who have low imaginative and prescient, this could also be beneficial.
“For blind students, basically for operational and safety reasons, assistance from sighted friends is needed for the set-up. However, as soon as it’s miles done they are able to feel the end-point of the test with the app and might participate actively in the laboratory setting, that is in any other case now not viable,” he said.
Often those students both pick out to stay out of the chemistry laboratory through themselves or face difficulties in actively participating in the laboratory sports, thereby counting on passive procedures of getting to know chemistry, the researchers stated within the take a look at.

The app could make the test greater enticing even for normal vision students.
For most effective running of the software, the laboratory room area has to have ambient white lights. In an obviously lit lab, the equipment has to be located close to a window, said Bandyopadhyay.
