Seminar 2 group notes

Discuss how the theory relates to your project?
Evaluation will be a difficult process for our target group, since the tourists are at their most useful when they need the most help. Once they have learnt how to use the ferry, they are very likely to pay less attention to the initial supportive function of our application. They will however still be useful for other functions, and we can conduct interviews in regular intervals to evaluate their experience.

Heuristic evaluation can be useful in our project to make sure we don't break standards unless we have good reasons to do so, but it will be difficult to do extensive end user testing for the same reasons as above. However, we can probably work out many of the issues by using experts in both technical areas, as well as to account for cultural factors. The user workflow can be evaluated through walkthroughs to the same extent. We want to stick to interface standards, such as the smartphone icon grid.

We believe that hypothesis testing will be needed to set the correct scope in terms of functionality. For instance, the AR camera function may be a huge component that very few users will benefit from, or it might be the biggest differentiator to the competition. Fitt's law can be used to measure the usability and accessability of our app.

What are the pros and cons of the methods you use? 
Pro: Natural observation can give representative results if the observed subjects are. A cognitive walktrough with a representative group can give us good insights into how the app will be used and how collaboration can work in group usage.
Con: difficult to get test subjects for natural observation.

Have you been able to apply them in an "appropriate" way according to the theory?
We have applied cognitive walkthrough throughout our design process. Many aspects of the use of experts have been applicable through our sharing of earlier experiences in the area. We also did a lot of natural observation during our interview sessions.

Are there any methods from the theory that you would like to use in the project? 
Yes.

If you had endless resources (time and money) how would you carry out your project?
We hire observers to observe tourists in their natural environment, and continously do follow-ups and evaluations to make sure we're up to date.
