Eye Sense for mobiles

Now since most mobiles come with the Camera, in the front and at the back the cameras can be used to sense the motion of eye or any other part of body to suggest commands to the mobile phone.

For e.g to make the mobile silent you can wink your eyes or keep you finer on your lips and say shhhhhhh.... !!!

More such apps can be thought of.

Wireless Data transfer between 3G and higher mobiles without using bluetooth

Since high end mobiles such as the ones supporting 3G + support high speed data rates for e.g upto 3 MBPS + and since they are data capable technologies, the same technologies used for uplink and downlink of data used in these mobiles can be used to transfer data between nearby mobiles without using bluetooth.

Voice based programming

The concept is to have the software code written for you as you speak.
The computer is fed with the information of the programming language you wish to code using VoiceXML. We can have multiuple language templates too.
once the XML is loaded the user an speak out his algo to the computer and the words are parsed analyzed and the code written.
For eg.
If the user has loaded a java template and speaks out
for i = 1 to 10
print i

the code would be generated as
for(int i=0;i<10;i++){
System.out.println(i);
}

The editor can also be programmed for editing, indenting all done via voice.
I implemented this Idea in 2002 as part of my academic project.
I also demonstrated the same in a software demonstration competition held at our college and won a prize.

digital pad for writing code from algorithm

The concept is simple.
There is a pad , a digital pad, on which you can write and is connected to a computer.
The Computer is able to understand the handwriting written on the digital pad by pre-trained database.
On the digital pad the software coder writes the algorithm and the same is transformed into code by the computer.
