Great work Afthab! It was a quite intriguing read, especially ‘Empathy’ part.

Thanks for the comments Sreeraj. Appreciate them.

  1. The brief given to us from the railway design center had warranted a screen based solution. Mobile phones were chosen instead of other kiosk based or Mixed reality based solutions because, visually challenged people use smartphones extensively in their day to day life, which was surprising given the lack of tactile feedback in a touch screen interface. The major deterrent was the noise from the railway stations that may disrupt the audio based navigation. It is for that exact reason bone conduction headphones were recommended, which at a cost of Rs.2000 is a bit expensive, but will become cheaper and is effective to help user distinguish the ambient noise and mobile usage. The mobile phones are worn around the neck with the help of a neck-strap by the visually challenged when using the cane to free their hands.
  2. True. Many airports and shopping malls use beacons for indoor mapping though. They monetize it effectively by pushing advertisements and giving analytics of user behavior, which ensures a positive cost to benefit ratio. That won’t be ethical in this particular case.
  3. I did not want to want to make a long article longer. There was a lot of things I had to omit for the sake of conciseness. In a live project proposal, technical feasibility also has to be considered.
