Preliminary round (Round 1):
1. Overall efficiency of the design (low power, high sensor efficiency, cost effective etc.)
2. Ease of use for consumer .
3. Modularity (easy customisation of sensors)
4. Comfort for consumer
Final Round (Round 2):
1. Feasibility of the prototype
2. Clear definition of advantages and limitations of the design
3. All criteria from Round 1 will hold
