I have read you requirement carefully, and after my analysis this is what i would like to do
Step 1) Create a application: (2 days)
Create a application that will read the tabular data, and display graphs using buttons, for this i would need sample data and the input formats
Step 2) Gesture Recognition: (2 days)
I will make a library of gestures for this i would need a list of gestures you would like to use along with any pthographs,(i would like more details about the gestures)
Step 3) Integrate both step 1 and 2 (2 days)
I have broken down the project into appropriate milestones, You can pay me after the work is done.
