Executive summary The full checklist is presented in Chapter 9. Highest priority items relate to best practice in: the provision of button feedback (including voice output) button design (including size, groupings and spacing) physical properties of the text display (including contrast and size) to make it more readable, and interface software design to minimise user intervention or to maximise simplicity of user interaction and to provide intuitive processes (eg for autotune, rescan, scroll, select, play recording) The research findings and design considerations were presented to industry at an interim juncture in the project. The project team received feedback that many of the checklist items are easily addressable by manufacturers in the product development process. 5. Next steps to support the availability of more accessible digital radio equipment It is RNIB’s intention that this research report, including the digital radio interface design checklist developed within the project, in conjunction with the comparative evaluation of currently available DAB equipment against the checklist, will support the availability of digital radio equipment that better meets the needs of blind, partially sighted and sighted consumers. In further pursuit of this goal, RNIB is engaged with manufacturers, others in the supply chain, UK and European industry and statutory bodies. 8
