Deciding on a Project Proposal

After meeting with Omar today, I've narrowed my project proposal down to either:

• An investigation into individual users' affect profiles when presented with stimuli.
• Compare affect response using different types of stimuli (e.g. images from IAPS vs video clips).

The first choice would involve quite a bit of technical knowledge in either data mining or signal analysis, and would require a more specialized experimental protocol. The second choice would be easier to complete but I'm not sure if it is unique enough compared to previous studies.
