HCI: Heuristics & Biases
- Heuristic/Bias 1: Choice overload- people get overwhelmed when they are presented with many options.
- Design principle: White Space
- Design in application: Limit the number of choices on one app screen so people are not overwhelmed with options. Make some assumptions about what the user will like so they don’t have to decide.
- Heuristic/Bias 2: Status Quo Bias- our preference for the current state of affairs, resulting in resistance to change.
- Design principle: Repetition
- Design in application: Use icons and designs that look similar to other apps/devices that are popular. We have been using Google icons so people know what they mean without explaining them.
- Heuristic/Bias 3: Primacy Effect- The tendency to remember the first piece of information we encounter better than information presented later on.
- Design principle: Hierarchy
- Design in application: Put the most crucial information at the top of each page so that people remember the most essential information and do not get distracted by less important features.
Good application of these principles! Btw, if you ever need more icons, https://thenounproject.com is a good source.
