BY IMAGINING USAGE FROM THE CONSUMER PERSPECTIVE, THE MOST INTUITIVE AND NATURAL CONSUMER EXPERIENCE WAS CONSTRUCTED The functional prototype consisted of a purchased kettle, retro-fitted with electronics that measured the water’s temperature, the volume of water in the kettle, provided temperature-related illuminated feedback and communicated with an app. The limitations of this prototype were that as it ran at 240V, the electronics couldn’t be tampered with as doing so would greatly increase the risks to user during testing, and cause issues during ethical approval. Instead, the retro-fitted electronics would be powered in isolation and would also require being turned on separately to the kettle. In essence it provided all the feedback and communication of the final design, but without the physical features for the blind, nor the on/off boiling control via the app.
