Thinking about this, wouldn't a plain old smartphone be a better platform for this project? That would give you a GPS location, video and still capability, accelerometer, network connectivity, user-friendly development environment and much, much more runtime resources available to you.
Ya that would be easier to do but for the sake of complexity.
8 people in the project group .Marks will be allotted based on how much work you do
So I'll have to use some complex device, Arduino platform in my case
and there will be enough work like interfacing the hardware,coding the hardware part , software part etc
for each member from the group
because in case of smartphone everything will be available readymade so the work divided will be very less for each group member
