I went to one of the shopping malls here with the vOICe. Security did not bother me but then I would not read too much into that since a lot of the guards are poorly trained. I was able to distinguish a wall of the parking lot from other things such as cars and assorted motorbikes while looking out of the left side passenger window of my car. Once I was inside the mall, the first thing that hit me was the sporadic rendering of images. I initially thought it was the netbook and glasses but dismissed that theory since the equipment had been running without errors on route to the mall. It seems that many lights in the mall are not switched on so there are patches of light and shadow. The camera is a pinhole camera and this makes a huge difference in how much light the camera can handle. So, most of the items on the shelves were lit by spot lights so they came out ok but the isles between the shelves and the corridor containing shops on either side were a different story.
I had grand plans of trying to identify the shop boundaries but this does not seem to be possible due to the lack of light. For anyone navigating in this mall, you need to keep close to the shops since they are better lit. The escalators were badly lit so I could not make much out. Still, an interesting exercise would be to stand on an escalator and use perspective to anticipate when you will reach the next floor. This did not work again due to the lack of light.
People also looked less curved and since I was getting less visual information, I had some trouble with perspective.
I had a look at shelves filled with different kinds of bottles. Shelves with packets sound different but you need to watch out for shelf boundaries. They can be quite useful in demarking one set of items from another. I tried looking into a freezer that had cold cuts etc but no go since that freezer did not have much light.
I then had a look at some clothes. It is easy to distinguish trousers that are hung on shelves from shirts that have also been hung on shelves. Sometimes though garments are stacked on shelves which complicate things since all that one really senses are the shelf boundaries with some patterns of clothing. Mind you while at the juice bar, I looked into a counter containing a number of juicers. They had the same rhythm as that of the trousers that I had seen earlier.
I was able to identify the opening of the door into a trial room. I tried tracking when the trial room door opened and closed but I did not have too much success with this since I had to keep moving due to the number of people in that shop. Plus, keeping my head still at a fixed location with a boring door to look at became cumbersome.
I had to set the vOICe to double speed otherwise; it was not as responsive to scene changes as I needed it to be. I made no other changes from the default configuration.

Hi Pranav,
The post is quite an interesting insight into how public places can be made more accessible. As for the badly lit places in the mall, I really don’t think they will make it better. Wouldn’t it be a good idea to have an integrated Infrared sensor in vOICe as well as a bar code scanner to get you a complete info about a product?
Do look at the extraordinary invention (SixthSense) by Pranav Mistry (www.pranavmistry.com). Videos and literature available on TED site. I am sure tech like this can make that critical change…
