What new functionality has been provided? What interface metaphors have been used? Are the functions and interface metaphor well integrated? What problems do users have with these interactive kinds of calendars? Why do you think this is?Briefly explain the stages of Donald Norman’s model of interaction?
- What is your opinion of emailing? How does an email get from point A to point B? Be certain to grant yourself credit for comprehension. What exactly is a distinction, and why is it so crucial? Examine the level of specificity in each model (or abstraction).The telephone interface design of the mid-1800s, early 1900s and the ‘landline’ telephones of the modern era; Considering the above mentioned 3 timelines answer the below question by compare-and-contrast across the periods specified In designing the interface, was any consideration given to biases in human behaviour? If so, what were these considerations and how did they differ in each era?What opinions do you have on the usage of email? What steps must be taken in order for an email to be delivered from A to B? Make a mental note of how much you understand right now. What does it mean precisely to distinguish between objects, and why is it so crucially necessary to do so?
