How can we extend performance models from the computer architecture to deal with heterogeneous visual computing architectures and interactive applications?
How can we find the adequate level of abstraction and the relevant parameters for making quantitative performance predictions?
Can our framework support an application to adapt to variable loads and conditions in real time?
Can we extend the model to the adaptive algorithms and the perceptual metrics investigated in other research projects?
How can our models be used to give guarantees for minimal frame rates or maximal interaction latencies for specific data sets?
How can uncertainty be dealt with in terms of both the measurements and the predicted outcome?
