(i) Discuss the various functional, ergonomics and safety requirements (needs) to be met by the design (requirements analysis) (ii) What design tools can you use to capture the various functional, ergonomics and safety requirements identified in (a) (i) above? (iii) What data should be collected and how should these data be analyzed in order to facilitate an effective design of the in-vehicle communication systems for the elderly (b) (i) Identify the ergonomics and safety design constraints for the proposed in-vehicle communication systems for the elderly (ii) Briefly explain how you can plan for these constraints and how you can incorporate these constraints into the required design (c) Develop a conceptual design of the in-vehicle communication systems for the elderly.
