Week 4

Exercise
This weeks exercise was to discuss the differences between high fidelity prototypes and low fidelity prototypes.

Exercise 1:

Elements of a car dashboard:

Steering wheel, volume control, aircon control, radio control, speedomoter, gas meter, gps, radio controls, air vents, windscreen wiper controls, window controls, horn, air vents, hazard lights button

Which compononents are relevant to driving behaviour:
Steering wheel, speedometer, gas meter, windscreen wiper controls, horn

What are the interactions of those components with the driver when driving:
The driver interacts with the steering wheel physically to redirect the car
The driver reads the speedometer and gas meter to adjust there driving behaviour
the driver interacts with the windscreen wiper controls and horn in response to external effects

What goal is implied by these specific questions:
These questions imply the goal of getting the car from one point to another by driving it, using it as a method of transport.

Are there other goals:
Yes. There are goals like 'making passengers comfortable' and 'keeping the driver awake'.

What would you test and how:
I would test the aircon controls using a vertical prototype, being a full replication of the aircon interaction system, with a simple seat+driving wheel mockup for the driver to sit in and feel like they are in a car while interacting with the aircon controls.
I would test that the controls are within reach of the driver easily, can be reached quickly and accurately, and can be manipulated by the driver without looking at the controls.
I would also test the responsiveness of the aircon and how quickly the user reacts to it.
The method of testing would be to place the tester in the driver seat of the car, ask them to pretend they are driving and need to do various things to the air con (ie, make the car colder/hotter, switch airflow modes, etc), then observe their interactions.

Exercise 2:

Horizontal prototype:
The phone allows setting and deleting alarms
The phone rings alarms one after another if an alarm is not stopped
The phone allows 2 different alram tones
The phone has a button to end alarms and one too snooze alarms

Vertical prototype:
The phone has an interface for setting, deleting and editing alarms, whith features like a calender for setting alarms for specific dates, and 'quick change' mode that allows the timeing of multiple alarms to be quickly edited.

Diagonal prototype: 
The phone allows for shaking the phone to snooze alarms that ring when the app is opened.
