class #1 Physical Interaction

What is interaction?
Let’s think about meaning of interaction. it means that people can communication each other. Here is the thing I have to think about between interaction and reaction. what is difference? I think reaction has only one way action or feeling. Think about turning on light, there are on/off switch. we pull up the switch, it turn on the light. By doing so, we can feel warm and comfortable but people cannot communicate with the light. On the contrary, The best example of interaction is talking each other. Today, people usually use the word,”interaction” even though it is reaction.

What is physical interaction?
I am so confusing about physical interaction. Does It mean interaction in physical environment, interaction with physical action or the other? Let me explain about physical first. According to dictionary, It means “of body”, “of material” and so on. This being so, The meaning of physical interaction is interaction using body such as shaking hands and interaction with physical things. Let’s think about talking each other. Is it the physical interaction? In my opinion, it is physical interaction. Some people say that talking each other is not physical interaction because it is not physical action. However it can communicate with people in physical world. Even though you talk to people using phone or other devices, it is also physical interaction because using physical things.

What makes for good physical interaction?
There are many thing to make for good physical interaction. The most important thing is environment for story telling. Think about interactive artwork. Most of them has no environment to communicate with viewers so it end with reaction.

One thought on “class #1 Physical Interaction

  1. I’m using the term “physical interaction” in a fairly specific way for this class, so if you’re confused, then hopefully it will make more sense as we discuss it more in class. But this might help:

    In the Crawford reading from class, he gives a pretty good definition of interaction: an iterative cycle of listening, thinking, and speaking. As for the “physical” part, remember that computers sense our action (that is, our part of our interactions with them) through their sensors. Unlike humans, however, they do not have language to interpret those sensor readings as anything meaningful, unless we program them what to do in response to a particular pattern of sensor readings.

    There has been plenty of work done in the past to give computers the means to interpret typed language, and to interpret gestures with a mouse or trackpad — and more recently, to interpret gestures on a touch screen. Designers who use these actions in their interfaces also have to train users to make the correct gestures. But the range of gestures or actions that a human can make that are part of the standard repertoire of computer-human interaction is very small. When we speak of “physical interaction” in this class, we’re speaking of designing and programming to increase the range of human physical actions that have meaning to a computer. It’s a two-way process: we have to figure out how to sense the actions a person might make, but we also have to train the human to learn what gestures the computer “knows”. Ideally, good physical interaction starts with gestures that the human might already make in communicating a particular goal, and adapts them as little as possible so that the computer can reliably sense them.

    What actions can a computer sense? That depends on the sensors we add to it, and our technical creativity in programming the computer to read the signals from those sensors.
