Bonanni experiments in the kitchen because, in his opinion, it is the
epitome of a modern space that lacks sensory feedback. Centuries ago,
a cook knew when his stove was hot because he could see the fire.
Modern innovation and automation have reduced the experience to
buttons and control panels that cannot always be comprehended
instinctively.
But Bonanni's kitchen contains motion, sound and temperature sensors,
as well as projection technology, that all work together to enhance even
the most common tasks.
For example, when a person turns on the water to wash her hands or
fill a kettle, a temperature sensor in the faucet head reads
the temperature and a light projects an appropriate color into the stream.
A
blue light indicates cool water, while a red light indicates hot. In a
pilot study, 94 percent of people immediately understood the visual
cue, which, according to Bonanni, could reduce scalds and easily
translate into less time running a tap to achieve the desired
temperature.
Overlaying audiovisuals onto other appliances can have similar
benefits.
For instance, most modern electric ranges have heat elements
hidden beneath a flat surface in a way that can make it difficult to
tell whether the stovetop is hot.
In fact, only 14 percent of the
people from Bonanni's study recognized a hot surface on such a stove.
But a video of a fire, complete with the sound crackling wood,
projected onto the wall behind the stove improved people's perception
to 88 percent.
