User Experience Design & Human Factors Engineering
User Experience (UX) design looks at the entire product use cycle to improve user-product interactions and understanding. Human Factors Engineering covers anthropometrics – body dimensions and limitations, and ergonomics – comfort and ease of use.
Using mock-ups to simulate real world conditions helped establish that the frequently-used mute button should be large and low on the screen. It should also change colour to indicate engagement. Critical assessments of mock-ups established that the screen angle should be adjustable to eliminate screen glare, and that the hinge must resist unintentional rotation. Anthropometric data was used to start designing the headset ear hook.
