Which Factor would you consider for a door handle?

Muscle Strenght

100

How many arms does a human have

2
100

True or False:

You should use a Ratio Scale to measure how comfortable an object is

FALSE:

Comfort if different for each person, meaning that an Ordinal Scale is ideal for measuring it.

Define Biomechanics

How the human body works like a machine

What does Hand Eye Coordination mean?

The ability to control eye and hand movement in synchronicity

200

Should arm length be considered when designing a table?

Yes

200

Define Fatigue

How long the human body can do something

200

Why is size relevent for the human body?

If the item is too big or too small it may not be usable 
200

How old is he?

300

What measure scale should be used when measuring Temperature

Interval for Celsius and Fahrenheit; Ratio for Kelvin

300
List 3 functions arms can fulfill

Grabbing, pushing, pulling, throwing

300

Define Comfort

The human body does not experience any pain

300

Translate the word Biomechanics literally

bios: "life"; mechanike "mechanics"

300

Whats the name of his dog?

400

Name all physiological factors

Muscle strength, Endurance, Visual Acuity, Temperature Tolerance, Sound Frequencies, Hand Eye Coordination

400

List the 4 considerations when designing for arms

Adjustment/Alignment, Relaxation, Motion, Standing/Safety

400

Why is fatigue detrimental when considering designs?

Fatigue can contribute to injuries and accidents

400

Why is it important to consider biomechanics?

Watching out for the limits of the human body, not overstressing or hurting it

400

Whats his favorite food?

You are driving your car and suddenly the vehicle in front of you loses control and starts spinning, you realize you cannot brake in time and decide to evade. However, the steering wheel is too heavy for you and you crash. What physiological factor is shown here? What design change could be made to help the driver in this scenario?

Muscle Strength; Power steering should be added to the vehicle

500

Why is it important to relax your arms every once in a while?

To improve blood circulation 

500
Explain a scenario where issues with comfort and/or fatigue lead to the failure of a product

Eg.: A bed causes neck pain and therefore suffers marketing issues

500

Name 3 considerations of Biomechanics

User age, Torque, User Interface, Size, Muscle Strength
