-how to maximise the range of users who can access the product
-the ease of use and suitability of the products for consumers usability
-international standard usability guidance ISO 9241-11. - 2what are the four usability factors? give an explanation with each pointEffectiveness: the ease of completing tasks with the product
Efficiency: how long it takes to complete the task using the product
Satisfaction: how enjoyable is it to use the product
simplicity: often results in a product that is easier to use - 3what factors do inclusive design involve?-taking into account factors such as age, gender, background, culture, size, weight and disabilities

-front design and size
-layout of controls
-user interface provided by software
-display screen clarity
-product weight
-consideration of sound and vibrations - 8what are some benefits of good ergonomics?-improved worker productivity
-enjoyable user experiments leading to increased sales
-removing the frustration of difficult to use products - 9what does anthropometrics relate to?anthropometrics relates to the measurements of humans.
- 10How is anthropometric data presented? Give examples of the measurements that are presentedanthropometrics data provided in charts and tables and give a wide variety of measurements such as arm length, knee height, and grip strength
- 11what are these anthropometric measurements usually grouped?these measurements are usually grouped by factors such as age gender and nationality.
- 12with anthropometrics what do designers need to consider?designers need to consider whether to cater for the extremes or the average and how adjustability can help
- 13how important is it to choose the appropriate percentiles for anthropometric data table?the appropriate choice of percentiles from anthropometric data tables is very important
- 14what do these percentile tables include?the 5th percentile, the 50th percentile (the average most common measurements) and the 95th percentile
- 15what does using the range from 5th to 95th percentile disregard?the extremes
