Affinity diagrams were used to help draw conclusions from the data in the research phase. The diagrams used data from both our personal research and research done within the class, they were created following a brainstorming session with group members. It consisted of a thorough discussion of the 'Dalek's' use cycle, physical and technical attributes and areas of improvement. This phase revealed these particular areas of improvement,
- Portability
- Organization of wires and technical components
- Ease of use (low learning curve)
- Ergonomics (screen angle) and Aesthetics (size and form)
Next, we developed Personas and Scenarios for the Projector unit. This phase helped with designing for the user and understanding what can occur during every day use. From this phase, I focused more on a low learning curve for my projector unit as well as portability to accomodate for the majority of users.
Following the brainstorming sessions, I developed another iteration of my projector unit design. This iteration had changes such as the re-positioning of the technical components and a slight modification to the technical package. I re positioned the technical components because they were unsafe on top and the risk of damage was too high. I changed the technical package to reduce moving parts and take away the need to adjust the projector. I decided to stick with a form similar to concept 2 for the final model because I received positive feedback about its transportation and the portability of the unit.
Once a final design was established, I created a 1:1 scale model of my projector unit which was constructed out of plywood, MDF and foam. I made these material choices rather than cardboard because I wanted to simulate the weight of what the real product would be. I tested portability issues by transporting it across campus through various obstacles. I also tested other characteristics such as size and the opening/closing function. The model gave me a better perspective of how it would operate in real life.
