I just filled a glass of water from the tap, but didn’t bother turning the lights on in the kitchen. Was interesting to hear the change in sound as the glass filled, and realise that this alone could be used to judge to level of water.
For what applications can feedback be provided solely by sound? And for what applications is there a benefit of providing no visual feedback? When driving a car, for instance, it might a distraction to have visual feedback. How does catering to a range of senses enrich the experience of feedback or detract from the objectives? What are the requirements of deaf or blind user groups?
I suppose what I am getting at is: are there any benefits of designing feedback of each sense in isolation?
