project on Bluetooth for Blind WE ARE BADLY IN NEED OF HELP.
posted 7 years ago
My Friends along with their students are actually doing a project on Bluetooth for Blind. The Project coding uses Netbeans IDE. Specifically MIDlets. The project is simple.
This is Lengthy I know. But I am helpless. So please spend some time to read and try to answer.
It is this: We would like to play an audio in Blind person's mobile phone when he reaches a specific point (ie., audio about the information of the place). We were able to develop a code which searches the mobile phone and we have TX unit which transmits an audio containing info about the fllor or building to the Blind person mobile.
But the problem starts here:
The Folder in which the files get stored are different in different mobile phones. Say in Nokia it goes to received folder. In sony ericson some where else. We should actually know where it is getting stored to play it. In Sony we where able to retrieve the path and play . But when we try the same logic with Nokia. The Receieved folder is not accessible. It shows the whole path along with all the folderes except this one.
Do you know any way of solving this specific problem?
2. One more problem is every time whether it is TX or RX to access the files it asks for an YES or NO to send or receive file. We do not want this option. We want it to happen automatically. The reason is We cannot expect a Blind person to press an YES or NO to receive and Play. We also found a solution But it is disabled. ie. We have an option called allow always. So we surfed Net. And we found that The problem could be solved with Midlet signing. We tried in Netbeans but we could not understand.Can any one tell me something about Midlet signing? What is the use of it? or Is there any alternative to solve this.
