The Inclusive Design Toolkit’s new online Exclusion Calculator enables better assessment for vision and dexterity. Also included in the Calculator are separate assessments for dominant hands and non-dominant hands in addition to vision, hearing, thinking and mobility. These enhancements build on the original Inclusive Design Toolkit, which was developed ten years ago and can be downloaded as a PDF. The upgrade takes designers through assessing the demands that a task, product or service places on a range of users. If you want to access the advanced version you will need to a licence. Years of research have gone into this tool. You can find out more about the research team and the calculator on their Home Page which has links to several other sections.
