Chapter 2
The author introduces conceptual models, which is pretty much a conceptual description of the purpose, behaviour and design of the proposed system. These models are dependant on the activities of the user, the four most common types of activites are:
- Instructing
- Conversing
- Manipulating and navigating
- Exploring and browsing
A good grasp of the average user seems to be of great importance in the designing of a conceptual model. Not only to find out what the system should do, but also how it should do it. This will give us a better grasp of what, why and how we are going to design a solution to an eventual problem of the interviewees
I think the four mentioned categories are an important aspect of the user and are really good to have in mind during when constructing a system. The user will be granted varying degrees of independence depending on the activity they perform. For example when reading a map of the musuem, how interactive should that map be? Should the user bew able to input their own keywords or should it just be a plain map? Can it be bad to allow the user more freedom in the interaction with the system or should interaction be more restricted?
