In Crawford book, interaction is:
“A cyclic process in which two actors alternately listen, think, and speak. “
It’s an interesting and vivid metaphor of interaction.
When doing interaction design between people and machine, I used to consider reaction as an interaction unconsciously and forget the most important cyclic input and output of machine. Thus, be clear on the definition is quite important for every interaction designer, like the state change of a indicator light of a machine is just a reaction, not an interaction.
Beyond this, I think interaction design should always provide an interesting or comfortable experience for users.
And in the video, our Future People are interacting with their hands. It is undeniable that hand is fantastic, but this idea may limit us. Through better sensors, we are able to sense body gestures, eye movements, heart rates. Like a Kinect could sense some certain navigation gestures to create better experience. Maybe in the future, machine could sense our feelings and emotions. At that time, your AC could control the temperature automatically by sensing your feeling, or your car will limited speed if you were angry.
Take the future AC as an example, I believe it is a kind of good interaction without hand.
Listing: Sensing people’s body surface temperature and humidity.
Thinking: Judging turn up or turn down temperature and wind speed setting.
Speaking: The machine providing cool or warm air.
Speaking: their body biological characteristic are transporting information constantly,
Thinking: their brain are judging the environment is too much cold or hot.
Listing: their feeling are sensing the temperature constantly.
People won’t take much care about their environment when the temperature and humidity is comfortable. Therefore, if the sensors are good enough, this interaction would be totally intangible for human.
And as a designer, I consider better user experience is one of the most important parts of interaction design. And with the development of technology, we could design and make better machines that could interact well with people and provide better experience. And the interaction would not only focus on people’s initiative thinking, but also passive neural reaction of people.
