Finding location of a blue laser's dot in a white wall image

Posted 11 July 2014 - 02:27 AM

My PC is located in front of my bed but is still too far to get up and change music when i'm chilling. So i was thinking of a new project to cover this need. I have a free white wall and a blue laser pointer. My idea is to be able to capture in real time the wall and point the laser at a specific place to next or pause the music or do any other functions. My only problem is that i need to process the image in real time and get the laser's dot location. im gonna write the program in vb.net. I tried to recognize the shape using AForge libraries but i was unlucky translating it to .NET. So im asking for your help if you have any other idea on how to get it done. Im testing it on a paper first using preshot images but im gonna integrate real time capturing afterwards. Thanks

Examples:
Note that the way im gonna use the location is by creating a grid with squares

Example paper with dot: http://i59.tinypic.com/n4tbls.jpg

First questions are first - have you just invested some time in getting a remote?
