Some of the 110 projects put up by the Singapore Polytechnic students ("Students develop smooth way for wheelchair users to enter flats"; Jan 22) have given practical solutions to real-life problems.
A good example is the automated wheelchair ramp - as mentioned in the article - designed to make it easier for the elderly and disabled to enter Housing Board units.
Another real-life problem faced by pedestrians, especially the elderly, is in avoiding being knocked over by riders of e-bicycles and bicycles.
Perhaps our polytechnic students could look into a specially designed reflector that can be conveniently clipped on to a pair of spectacles.
This will enable the wearer to take notice of moving objects approaching from behind and avoid being hit.
This innovation will result in better safety for all pedestrians.
