Section 8.3 Quiz: Designing accessible mechatronic systems

1. Which principle of universal design focuses on minimising hazards from accidental actions?

   • Equitable use
   • Flexibility in use
   • Simple and intuitive use
   • Tolerance for error {data-correct}

2. What is the recommended optimal height range for controls to accommodate wheelchair users?

   • 380-600mm from floor
   • 600-1000mm from floor {data-correct}
   • 1000-1220mm from floor
   • 1220-1800mm from floor

3. For users with limited grip strength, what is the maximum recommended activation force for controls?

   • 10 Newtons
   • 22 Newtons {data-correct}
   • 35 Newtons
   • 50 Newtons

4. Which of the following are essential components of an accessible emergency stop system? (Select all that apply)

   • Multiple stop button locations {data-correct}
   • Voice command activation {data-correct}
   • Low force activation requirements {data-correct}
   • Complex authentication procedures

5. What does “dwell time” refer to in eye tracking interfaces?

   • The time between eye movements
   • How long a user must look at a target to activate it {data-correct}
   • The delay before the system responds
   • The time needed to calibrate the system

6. Why is multi-modal feedback important in accessible mechatronic systems?

   • It reduces power consumption
   • It accommodates users with different sensory abilities {data-correct}
   • It makes the system look more advanced
   • It simplifies the programming requirements

7. In the context of accessible design, what is the purpose of “force limiting” in safety systems?

   • To reduce power consumption
   • To prevent damage to mechanical components
   • To protect users who may have reduced sensation or awareness {data-correct}
   • To comply with noise regulations

8. Which accessibility consideration is most important for long-term system usability?

   • Initial cost reduction
   • User-adjustable settings that can change as needs evolve {data-correct}
   • Standardised interface colours
   • Minimum training requirements
