Interaction Design

Ch 5: Beyond Human-Computer Interaction

This reading discusses how expressive forms are meant to produce an emotional response in users. Expressive forms do not just apply to humans, but can apply to objects, such as a phone waking up after it has been asleep. The appearance of an icon on a phone is very reassuring to users as it shows the phone is functioning properly. It creates a sense of friendliness and the user may even smile back. One of the benefits of using expressive embellishments in objects is that they can provide reassuring feedback that is informative and fun. Different interfaces create different emotions. A frustrating interface will create a negative emotion, just as a user-friendly interface will create a positive emotion. These interfaces can also be persuasive and get their user to do something.

The most important reason on why to use a grid is that it brings order to chaos and creates a fail-proof system on how to organize your data.

In this video, the term “Form follows Function” is discussed. This saying means that first a design must make sure things work, and then make sure its beautiful. However, this video discusses the other laws of nature that suggest form may not always follow function. The aesthetic-usability effect is one of these laws. It describes a phenomenon that beautiful objects are perceived to be easier to use than uglier objects.
