Assessment Task 3 (ANDY)

1. The history of human and computer interactivity:

For the first 10 years of computers existence, computers were large, expensive and not personal to us. The were mainly used for communications between countries during the wars and figuring out calculations. It wasn't till the 1980's that computers slowly became a necessity for the average household to have.

Input & Output Devices

To input a device to a computer is self explanatory, something like a microphone, mouse anything that makes something go into the system. While an output device is quite the opposite and sends something out of the system like a speaker ( the sound is coming out of the computer).

How do they effect Human to Computer relationships?

Input and output devices are important to the relationship between computers and humans because it is what makes a computer interactive with us. A button is an input device and without that we wouldn't be able to click the mouse, type words or get anything done. A screen is an output device because it is an interface that is showing us what the computer is doing; without these basic things a computer and a person would have no interaction with each other at all.

HyperText

Hypertext is text on an interface that when clicked transports the user to another webpage.

Interactivity Assessment Task 4 (ANDY)

1. Working in small groups of 3 or 4 people, use paper to make the following interactive artefacts: • Something that travels • Game • Puzzle • Decoration • Musical instrument • Item of clothing Our result :

Assessment Task 5 (DAVID)

Raster Files are a dot matrix pixel system that displayed images width and height. Pixel grids represent the amount of pixels an image is using. Often seen on softwares such as Photoshop or Illustrator to allow the user to see how large aspects of their images are. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. Resolution is what defines the quality of a screen. The higher the resolution, the more pixels per inch there are which evidently results in HD. But if there are ew pixels such ass 180x240px the resolution will appear poor. The x,y and z coordinates system works just like it does in maths. x being across and y being height and z being depth. The aspect ratio describes the ratio between the sides of a shape, the better the ratio the better quality and the better it'll look. ...

Tech Task 6

Every time the mouse is clicked the shapes will move to a random position with a random number of squares. T hen I created a white ball that bounces from one part of the screen to another while creating a gradient fade trailing behind it to make it have gravity realistic aspects.
