Unit 1 - Workspace Design

Question 1

What are the layout priorities for workspace design considerations?

Answer 1

• grouping controls functionally or sequentially
• consistency in layout for ease of use (ie. once we make a leyout, helpful for other spaces to also have it)
  *surgeon tools example, in order of how you use them

Question 2

What are the design considerations for dynamic measures?

Answer 2

grip strength, exerted forces (push, pull, lift)

Question 3

What are the reference points and zones (design considerations)

Answer 3

• seat, arm rotation, and eye reference points
• visual envelopes (refers to the optimal viewing area for displays)
• Design eye position (DEP)

Question 4

define DEP

Answer 4

*design eye position
- the position from which the user is intended to view the workstation for an optimal view of the visual interface

Question 5

describe the first prototype in the history of the keyboard

Answer 5

• christopher sholes, early 1870s
• used piano keys as first keyboard, created patent on design
• spaced awkwardly though and had strain on wrists with alphabet straight across
  *wanted to space out more commonly used letters and group them based on English language

Question 6

Describe the 2nd model in the history of the keyboard

Answer 6

• Christopher sholes 1868
• put all the vowels together in the middle section

Question 7

describe the 3rd model in the history of the keyboard

Answer 7

• christopher sholes & partner sold their rights to Remington & Sons 1878
• qwerty keyboard
• numbers went from 2-9 (could use i or O)
• can type many whole words with left and right hands

Question 8

layouts of our workspaces are _

Answer 8

very impactful in our movement efficiencies (not on slides)

Question 9

define visual envelopes

Answer 9

• includes objects we can see with our left eye, both eyes, or right eye

Question 10

What visual envelope activity did we do in class?

Answer 10

what can we see in peripherals?
- looking at movement, shapes, colours, words (could see in that order)

Question 11

When we look straight at something, light goes _. When it comes from the side, it _

Answer 11

light goes straight back to retina
- light hits the back side wall of the eye when from the side

Question 12

describe the distribution of rods and cones

Answer 12

cones - colour, rods - black and white
- not evenly distributed
- highest density of cones in middle
- scientists say fovea is super valuable cause we can see things super clearly in line with it

Question 13

Evolutionarily speaking, why are our cones and rods distributed the way they are?

Answer 13

• periphery is where we need to know if someone is sneaking up on us
• in the center we can see clarity, colour and shape, see more detail
• our most optimal is at the middle
