The aim of this assignment is for you to think about the appropriateness of different kinds of conceptual models that have been designed for similar physical and digital information artifacts;

Compare the following:

a personal paper-based calendar versus a digital calendar (i.e. diary);

a shared paper-based wall planner versus a shared web-based calendar.

What are the main concepts and metaphors that have been used for each (think about the way time is conceptualized for each of them)? How do they differ? What aspects of the paper-based artifact have informed the digital calendar? What is the new functionality? Are any aspects of the conceptual model confusing? Do you use a paper-based or web-based calendar? What are the pros and cons of the one you use?
