E.On - Screen Based energy monitor interface. - Brief from E.On to design a screen based interface for an energy monitoring system aimed at 40-60 yr olds.
User research and persona generation showed that most 40-60yr olds would either not own or not use a smartphone, PC, or tablet on a regular basis, or would not entertain the learning curve involved in using it for a new application.
They would however be willing to use a simple interface that they could switch quickly and easily to on their digital TV set-up, especially during ad breaks.
