Indore (Madhya Pradesh): Measuring units and observation is one of the most necessary skills for doing experiments, but how can a blind person perform scientific experiments? Innovations in science have given the opportunity to all those people who carry out experiments. Dhananjay Gadre, director of the Texas Instruments Center for Embedded Product Design, Netaji Subhas University of Technology in New Delhi has developed instruments for the visually impaired.
The instruments can weigh, measure, identify and perform general people observation skills and are equipped with a speaker. The institute has developed more than 14 such instruments that can be used for laboratory experiments in physics, chemistry and biology. These were shown to the students of the Institute of Engineering and Technology at the international conference.
“The instruments can be attached to the weighing machines where they have the ability to weigh the chemical or the substance stored in the machine. The instruments are developed in such a way that they work on the chemicals stored in the machine. The chip of voice can indicate the weight, where the visually impaired can hear and perform the laboratory activities with ease,” said Gadre.
The instruments are being tested by the National Council for Education Research and Training (NCERT), where they will be certified for 2 months. Gadre said that they have sent 2 sets of each instrument to the Delhi headquarters, where it will be rectified after receiving feedback from the visually impaired.
Instruments for identifying colors
When it comes to chemistry and biology lab experiments, it is important for the observer to know the color of their product. The institute has also developed an instrument that can identify the colors of litmus paper. Gadre informed the Free Press that a litmus paper needs to be installed in the instrument, where it has the ability to identify and write the color of the litmus.
A revolutionary step
“If these instruments successfully get a pass certificate from NCERT, it would be a revolutionary step in the field of laboratory science. Visually impaired people will be able to conduct experiments and excel in the field of science,” he said. Gadre
