Evaluation
After the first two co-design sessions with our participant it became clear that he did not necessarily have a wish in mind for a certain product or innovation. He seemed a very happy man that was content with his life. Therefore we looked into the activities, hobbies and problems that he has, in order to find a design direction. The participant joins activities at Plint, there a does activities that focus on creativity, ambitions and sporting. He likes to take part in sporting activities around four times a week which include lifting weights and rowing. His hobbies include ‘kegelen’, a form of bowling, and listening to Dutch music. There were also some issues that he faced in his daily life. For instance he had difficulty travelling by train, because he couldn’t easily enter the coupe. He also couldn’t enter certain buildings because they didn’t have wheelchair access or were to small. This includes certain shop and the local place for ‘kegelen’.
Method
During the evaluation the physical prototype will be present and used. The physical prototype consists out of the mechanism and the device, for the device a phone is needed to simulate the interface. The participant can use the prototype during the evaluation. When he is using the prototype, he can give his opinion and some tips to improve the product.
Test conditions
Throughout the whole test, the conditions should stay the same. In this case the environment and other conditions do not influence the use of the product. The conditions should be similar to the expected use situation. This means the user will be seated in his actual wheelchair, at home. Another important aspect is that he will not be helped during the testing. He will get a short explanation, but after that he should use the prototype on his own.
Step by step approach
The step by step approach is described here:
- Show the prototype to the participant
- Explain to the participant how the prototype should be used
- Ask if clarification is needed.
- Attach the mechanism to the wheelchair
- Let the participant use the prototype in collaboration with the designer
- Ask if he understands the steps that he should take, and if not, explain
- Let the participant use the prototype on his own
- Ask the participant’s opinion on the prototype
- Does he like the prototype?
- Does it work as expected?
- Are there things that should be improved?
- Is the product self-explanatory enough?
- Is the position relative to the wheelchair and the participant of the prototype convenient enough?
- What does he think about the shape of the prototype?
- Does the product fit his style enough?
General evaluation
We will rate our product based on our requirement, the scores are: Good , Medium and Poor . If we were not able to test this the requirement a question-mark is writen. This will demonstrate if we accomplished our goals of beginning of the project.
Functional requirements
- The product should fit our user
- The product must have an interface that could be seen by the participant
- The product must include big icons and buttons
- The product must have the option to be attached to a wheelchair
- The product should be able to attach the bar on his bed
- The product must allow the user to control the music (skip, pause, play, previous song)
While the product has the main functions that the participant wanted, the interface could have been made even bigger. Since the group focussed mainly on making a (partially) working prototype, for which a mobile phone would be used, not the entire ideal area was used for the interface. Furthermore, the choice was made to have the product be attached to the wheelchair only, because the participant would need it when travelling or being outside. Thus, having the ability to attach the product to his bed was unnecessary and therefore left out.
Requirements for the style
- The product should fit the personal style preferences of the participant
- The product must have high contrast in the parts that are often used to operate the device
- Avoid overcomplications and over-accessorising
- Do not use more than 3 colours in the whole design
- The product uses mainly primary colours with black and white
Style is one of the elements that was very particular to the participant and well-integrated into the design. Not only the colours, but also the shape was made to imitate the looks of Ferrari, which he liked. Furthermore, the design had to be fairly simple and uncomplicated.
Technical requirements
- The product should be rechargeable
- The battery of the product should last at least 16 hours
- The product should have a light weight and small design and not exceed the weight of 2 kg and a volume of 200mm x 200mm x 50mm
- The product should have an AUX input (to attach earphones)
- The product should be connected to other products by using WIFI/Bluetooth
- The product should be water and dirt resistant.
- The buttons should give visual/audio feedback when pressed
- The product should be easy to clean from dirt and dust
- The casing should be sturdy/withstand the fall from 2m
- The product should the user allow to:
Play and pause the music; Change to the next song or go back; Adjust the volume; Turn the device on and off
- The product should give the user information on what song is playing
For this project, the main focus lay on making a physical, semi-working prototype that would fit the participant’s needs. Specific technical requirements like the product’s battery life and connection options were outside of the group’s attention. Additionally, sturdiness and resistance to water and dirt were not tested out. However, physical inputs and buttons were realised as well as an interface.
Wishes
- The product could include a touchscreen
- The product could provide the user with notifications from for example emails or phone calls
- Some aspects of the design language of Ferrari could be included
- The product could provide a light for the user in the dark to find his way back home or helps him find the keyhole in the door
- The product could give the user information about the weather
Although the product was mainly intended as a music player, the participant also thought of some extra functions he would like. For this project, not all of them were addressed, since these did not seem to add a lot in the use context of the participant being outside. Nevertheless, the function of calling and being called were implemented into the design as this could be very useful.
Results & conclusions
Results will be put up after the evaluation.
