Project 1 - Testing Session 1

What did you observe?

What did you observe and note as you watched users interact with your prototypes?

  • Other friends would zoom in on my sketches and ask questions about the structure, and I would make notes on areas that needed further structural refinement.

What feedback did your users share after the testing?

What feedback did your users share after they've had a chance to interact with and explore your prototypes?

  • Brand name, how will you label it? (Will this container be refillable for all the different branded products that each individual uses?)
  • If the plastic is biodegradable, how will you preserve the cosmetics without a chemical reaction?
  • Why not just sell the soft part instead of the hard bottle?

o Vinyl type:

  • TPE (thermoplastic elastomer): A flexible yet durable material that combines the benefits of elastomers and plastics.
  • LDPE (low-density polyethylene): Highly resistant to oxidation or degradation and protects contents
  • PET (polyethylene terephthalate): Resists degradation, provides transparency and durability
  • PP (polypropylene): Excellent heat and corrosion resistance, prevents deterioration and oxidation
  • EVOH (Ethylene Vinyl Alcohol Copolymer): High oxygen barrier to protect contents and extend shelf life

o Environmentally friendly type of vinyl:

  • LDPE (low density polyethylene): Recyclable, low energy consumption and carbon dioxide emissions in production
  • Biodegradable vinyl: A material that can be naturally degraded under certain conditions.
