I went over to the Samsung office and read all the papers they asked me to sign. One of the documents was very interesting.
The first 2 pages of it state that Samsung can claim anything I do on and off the clock and on and off the Samsung premises while being employed by Samsung. But there was a single line on the third page that states I can list all the projects I started working on or worked on before joining Samsung, and Samsung cannot touch them – so I did exactly that.
Also I asked the HR person to get the written approval from the directors and mangers at Samsung that I have the permission to work on Gesture related projects. They all said it's not a problem.
