Rajesh, <snip Is it particularly helpful in navigating alone indoors or outdoors? I realized that I had not answered this part of your message. When you start using the vOICe, you must always try it in a safe environment. This usually means indoors around your house so that you are familiar with the objects in that environment and can related your impressions of them to the input the vOICe gives you. I use the vOICe regularly for indoor navigation. My office is very cluttered so the vOICe helps me navigate around the office. The office is a shared space so I cannot ask people to move opsticles around. It also helps me get more information about the external environment. However, the lack of a wide field of view of my webcam limits what I can do as of now.

This mail of yours gives an impression that the software can be used extensively to know shapes, colors and even their exact position. I have also listened to the chat. Now, I would like to have some hands-on-training to use it optimally. Is there any training link on the site? Maybe, there is, but I could not open it. Please guide further so that such a software can be of maximum use. Is it particularly helpful in navigating alone indoors or outdoors?

You can get it at http://www.seeingwithsound.com You need the mobile java version of the vOICe. The vOICe does work with Talks and I believe with mobile speak. The vOICe can report colors of the shape that is in the center of the camera view. However, an interesting mode is the "analyze" mode where you can set the vOICe to cycle through all the colors it knows. It will then speak the color and will also then sound that part of the view. So, if you have a blue tea shirt with green stripes, the vOICe will sound the blue part of the tea-shirt when it says "blue" and then also sound the stripes when it says "green". This is handy for situations where you have items that have more than a single color. There is also a color filter where you can set the vOICe to sound objects that have a specific color. So, if I am looking for the green biscuit box on a table, I set the vOICe to only tell me about green objects and then focus the phone on the objects on the table. Once I hear a sound, I determine its position and then reach out for the box and take it. I have a blog that is mostly about the vOICe. You can see it at http://techesoterica.wordpress.com. Note: For those of you who want to access the seeingwithsound.com site on your mobile phones, you can navigate to http://phone.seeingwithsound.com and download the vOICe from that page. When using mobile phone based color identifiers, you need to take ambient lighting into account. Colors appear different under different levels of light. Do remember to keep the camera in a way that light falls on to the object that you are examining. I have been often asked what is the difference between a mobile phone color identifier and a dedicated color identifier. The difference lies in a reference light. Dedicated color identifiers have a reference light that can be used by the color identifier when checking the color of an object. Mobile phone color identifiers do not have such a light hence the variable accuracy. You could well ask why not use the flash incorporated into most mobile phones? The problem lies with the programming support for the flash in java and how well symbian and other operating systems support this across phones. There is a surprising amount of variability in the kind of java support available across phones. Pranav To unsubscribe send a message to [email protected] with the subject unsubscribe.
