Prediction:
- To froth milk for lattes and other coffee drinks
- The coffee/latte drinking market or home consumers and coffee shops
- Design Objectives: hand held, easy to wash, metal (swirly part)
- Constraints: cost, weight, speed, batteries
Observation:
- Have a glass of a small amount of milk, use frother in milk
- DO: meets expectations, designed for easy simply minimal effort frothing
- Affordances: hold it in your hand, two parts
- Mapping: Gear/widget is for functionality and turning it on, metal part is where the milk touches the object, batteries have +/- signs, gear does not have mapping
Test:
- Functionality → it works and it grts the job done, it is highly operational and ergonomic that it is fast and easy to use, fulfills its task, the milk is frothed
- My own device → IT WORKED?! Shaker w/ covered lid. Fulfills the task but not as thoroughly as the motor/battery powered one (human shaking v. machine)
- Affordances: you must hold it in your hands, there’s a cover/cap to it that is meant to stay on, you have to shake it, and put in a certain amount of milk.
- Mapping: Line to fill milk to, the swirly wires willmove in the cup
- Strengths: not too much effort to shake
- Weaknesses: you have to shake it, your human power makes the bubbles
IKEA Device:
- Metal cylinder with rod attached to a conductive motor
- Made by assembly, probably a machine or a human
- # of parts → approx. 25 parts in total
- Moving parts → 3
- Surprises → the metal part on the inside
Analyze:
- Picture given:
- Total cost: $0.50
- Strengths: efficient and fast, lightweight
- Weaknesses: if the top part gets wet the motor that powers it and the batteries are finished
- Refinements: on and off engravings or a down arrow for the gear
- Disassembly: things are a lot more complicated than they seem!
