I like the lecturer, but using a ultrasonic sensor to 'detect' above waist obstacles is not a novel or i would argue a good idea. There are probably close to 500-1000 projects which do exactly the same thing. And despite this number of projects there is no widespread adoption within the blind community, because it's heavy, needs to be powered and in the rare cases that above waist obstacles are present ultrasonics sensors can have a variable/poor reliability in terms of detection. Is it a person or a tree. If it's a tree than unless the ultrasound gets reflected back then it wont be detected. Good lecturer but i ultrasonic sensor canes are blight on the blind community and take away attention from actual novel research which could make a difference.
sir is a brilliant professor, I did one course under him during my first year at IITD. It was fantastic. And he gives THE best speeches.
