Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context Rina chooses one low-risk lamp action and keeps a reachable manual switch and support-person call signal throughout the session. The assistive-technology team configures access while Rina practises activation, confirmation, cancellation, false-command detection and network-loss recovery. Nothing here authorises control of heat, cooking, medication, doors or security. Target outcome: With the assistive-technology team, the user activates, confirms and cancels a chosen low-risk device action, detects false commands and recovers from network loss. ### Authority and setup conditions - Have the qualified assistive-technology team approve the user goal, access method, device and permissions. - Use a low-risk training lamp and verify manual/human fallback before pairing. - Start check for Environmental control systems: Scope and permissions cover only the training lamp. - Top-of-sheet stop for Environmental control systems: Stop for repeated false commands, inaccessible cancel, uncertain state, switch shift, fatigue or distress. ### Required or supplied materials - Declared Environmental control systems fixture: Rina chooses to turn a training lamp on and off from a configured switch.

Score a no-action trial correct only when the lamp state does not change and no command is emitted. ## 1. Choose the user-prioritised action Rina confirms “lamp on/off” as useful and identifies who may change settings; no one adds door, heat or appliance control. Why: Scope and permissions cover only the training lamp. Success check: Scope and permissions cover only the training lamp. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Scope and permissions cover only the training lamp.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Assess reliable access The qualified team checks switch position, activation force, posture, fatigue, vision/hearing and false-hit risk. Why: Rina can intentionally activate and withhold activation in the tested position. Success check: Rina can intentionally activate and withhold activation in the tested position. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Rina can intentionally activate and withhold activation in the tested position.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Configure least privilege The technician pairs only the lamp, labels on/off state and disables remote routines or other devices. Why: A command cannot reach an unapproved device. Success check: A command cannot reach an unapproved device. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “A command cannot reach an unapproved device.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Teach activate–confirm–cancel Rina presses once, checks the visible lamp-state cue and uses the agreed cancel/off action before another command. Why: The lamp reaches the intended state and the user can reverse it. Success check: The lamp reaches the intended state and the user can reverse it. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The lamp reaches the intended state and the user can reverse it.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Practise ten trials Mix on, off and no-action prompts; record correct commands, misses, false commands, time and assistance. Why: All prompts, including no-action trials, are scored. Success check: All prompts, including no-action trials, are scored. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “All prompts, including no-action trials, are scored.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Test ambiguous activation Deliberately place the switch near but not at the reliable position; if false hits rise, stop and restore the assessed setup. Why: Configuration error is detected rather than trained through. Success check: Configuration error is detected rather than trained through. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Configuration error is detected rather than trained through.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Simulate network or power loss The technician disconnects the safe training link; Rina uses the manual switch or call signal and the team confirms the device’s fail state. Why: The fallback works without repeated commands. Success check: The fallback works without repeated commands. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The fallback works without repeated commands.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Review maintenance and control Record user satisfaction, burden, false operations, update owner and review date; Rina decides whether to keep the action. Why: User control and failure recovery accompany performance data. Success check: User control and failure recovery accompany performance data. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “User control and failure recovery accompany performance data.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt.
