Provide the setting and context, and let users understand the action that's expected from the cues given.
three categories of physical computing projects: expressive works/ instruments or tools/ instructional works.
transduction: sensors(senses) and actuators(muscle). Computers don't know anything about a participant except what they can sense from the energy changes the participant generates.
digital(binary) / analog (continuous)
explicit interaction: the action is primarily intended to send the computer a message. / implicit interaction: it has other primary purpose, and sending the computer a message is a secondary effect.
Give participant actions(to jump), not states of being(to be scared).
Make participants feel comfortable and safe, break down their inhibitions, and get them more engaged.
Give people reasons to cooperate/ compete/ use the whole space.
Find the moment between decision and action.Engage.(Is that so??)
Use the whole body.
Nothing is intuitive. Everything is learned.
automation(listening, measuring, quantifying) / interaction(enhancing what we do best).
Components
conductors
insulators
resistors (including potentiometer, photocell)
capacitors(smooth out the dips and spikes in an electrical supply)
diodes (anode, cathode)
switches(momentary, toggle)
transistors (electronic switches, usually used to control high-current loads like motors) & relays(slower and more prone to wearing out)
votage regulator
flex sensor (work well for measuring the bend of a finger)
Without highly legible systems for managing and understanding all of this ‘smartness’ we are going to get very lost and highly frustrated.
Questions:
[ ] what is the difference between ordinary switches & transistors(smaller voltage to control circuits with larger circuits) & delays(magnetic way)? When to use switches & when to use transistors?
[ ] how does roller switch work?
[ ] A little(actually a lot!) hard for me the understand Best design is invisible?. I guess it needs more experience to fully understand it.
