Design Principals Revision
Buisness
Crash, Not easy use, look bad, not cover needs
Beat competition, Easy to use, customers come back, money, nice reviews
Hardware + Software = Platform
Mac on PC, Android on phone, Nintendo on Switch all of the Operating Systems run on their own brand for example apple software only runs on Apple products
The interface may be good at completing the taks but if the user cant use the interface then they will not use it. You need to consider what type of user (novice or expert) is using the interface and how much help they need. The interface must be new and intuitive but people have to be able to predict how it works. And the design layout used selection time
Different people will have levels of Using UI. Therefore when choosing the features of the interface think about which features are accessible and which are new. As some people may think the UI is accessible if there is help.
Choose what tasks needs doing and whether your interface can complete these tasks. You need to consider what is necessary for the user to do a simple task.
Some users may have accessibility needs like sight or hearing. Developing a UI that covers everyone of the needs is impossible. But it needs to meet most needs to customize to meet them
Complete tasks on the interface quickly. As you don't want to wait ages to do a talk
The amount of storage space needed will determine what UI will be used and what features it will have. There needs to be a balence betwen ease of use and storage space.
Allows user to enter info in specific fields on a screen. Can be controlled by scrollbars or drop downs - contact book
text based screen and use a keyboard to interact - python
Menu choices that a user can select to move - cinema booking
Complex Interfaces
monitor conditions to trigger an action - touch ID
Give instruction with speech or sounds - SIRI
Icons and visual features to make selection for navigation or action - I phone screen :iphone:
There are four types of user expert, regular, occasional and novice.
Complete most tasks on basic interfaces, need help to do a task, need little help, navigate an interface while thinking, use trial and error
Use common interfaces to do tasks, do a task several times before confidence, navigate an interface but stop to think
Lots of experience with tech to do a task, navigate interfaces on their own, know what to do without thinking, predict what a tool will do before use
little or no experience on interfaces and may be able to do a task, supervised by a user with greater skill, may not know how to go about a task to do it.
Accessiblity
If someone is deaf then some text (alt text) or subtitles may need to be provided to make sure the interface is accessible to everyone. Visual needs alt text is also needed.
