homework day 1 – Michael

Circuit 1: Fade

Circuit 2: toneMelody

Circuit 3: Speed Game

DOCUMENTATION:

1) Take the “fingerprint lock” as an example: In this system, if we unlock an object (our phones, for example) using the correct fingerprint, the screen will gradually be brightened with the phone itself making a “unlocking” sound. In this way, I think interaction is just how people and objects interact: we people input information to machines, and, at the same time, these machines send a feedback to us to imform us the information we suppose to know.

2)

resistors — to add an extra amount of resistance to change the volts between two ends of an object and the current in the circuit

LEDs — to output the light as a source of information (it seems that the LEDs we use are all diodes)

wires — to transport energy

buzzers — to output the sound as a source of information

breadboard — to connect different wires and objects and thus form a whole circuit

CPU(Central Processing Unit) — to be a transfer station between the circuits and the computer, mainly; to store the program and to run it

3)

Human-computer interaction has changed a lot by now. This technology is never restricted to the interaction only between human and computers any more. Having influenced in many areas, HCI will surely be developed into more spheres and be deeper used in those areas. Through this fast developing technique, it is possible for us to achieve our creative ideas in the near future.
