Toyota Hilux HCI Analysis

"this heuristic refers to how well the state of the system is conveyed to the user"

"systems should always keep users informed about what is going on with appropriate feedback within a reasonable time"

"this system status could be persistent or always visible like a battery life or a WiFi indicator  OR 

it could be feedback that is only shown after a user has done something"

When users know the current system status, they learn the outcome of their prior interactions and determine next steps. Predictable interactions create trust in the product as well as the brand.

"users sometimes often choose a function by mistake and need a clearly marked exit...  Basically support undo and redo"

When it's easy for people to back out of a process or undo an action, it fosters a sense of freedom and confidence. Exits allow users to remain in control of the system and avoid getting stuck and feeling frustrated.

Questions:

• Are users offered easy ways out of as many situations as possible?

• Are there clearly marked ‘emergency exits’ for users to leave unwanted situations without having to go through several stages?

• Support for undo and redo, e.g. Ctrl-Z & Ctrl-Y

• Cancel button (for dialogue boxes waiting for user input)

• Universal undo (can go back to the previous state)

• Interrupt (especially for lengthy operations), e.g. Home button, “ESC” key

• Quit (for leaving the program at any time)

• Defaults (for restoring a previous state)
