A Train-the-Trainer Guide

Use highly structured, absolute orientation terms. Ask for permission to guide a client's hands as useful during instruction. Direct the client to hold the glasses by the temples (arms) with the lenses facing completely away from their body. Instruct them to perform the following tactile sweeps:

• The Left Temple (Power Switch): Instruct the client to pinch the left arm close to the front lens hinge and locate a small, raised, sliding switch on the inside surface. Dictate the action: "Sliding it forward toward the lens turns the glasses on. Sliding it back toward your ear turns them off."
• The Right Temple (Control Hub): Inform the client that all interactive operational controls are consolidated on the right arm.
• The Touchpad: Direct them to place a finger flat on the outer lateral side of the right arm. Instruct them to slide their finger back and forth to locate a long, smooth, slightly recessed or uniquely textured track.
• The capture button: Instruct them to move their finger to the top edge of that same right arm, close to the hinge. They will locate a small, distinct, raised tactile button.
• The Power/Action Button: Direct them to move their finger down to the outer lateral side of the right arm near the hinge to locate a separate small, raised button.

Instruct the client to put the glasses on and listen for system sounds:

• Power On: An automatic ascending acoustic chime plays when the frame sensors touch the face.
• Photo Capture: A crisp camera-shutter sound confirms a static capture.
• Video Recording: A distinct chime sounds at the beginning of a recording, and a separate trailing chime sounds when recording stops.
• Incoming Communication: A combined frame vibration and audible ringtone signals an incoming call.

Instruct the client to check battery status anytime by asking, "Hey Meta, what is my battery percentage?". Teach them to listen for the vocalized percentage, ensuring they can manage device longevity independently without a smartphone screen.

To ensure the client understands both operational tracks hands-free, use the following interactive verbal checklists.

• Capture Photo
  • Voice Command Syntax: "Hey Meta, take a photo."
  • Physical Shortcut Interaction: press the top capture button once.
  • Verification Method for Trainer: listen for the camera-shutter.
• Start Video
  • Voice Command Syntax: "Hey Meta, start recording."
  • Physical Shortcut Interaction: press and hold the top capture button.
  • Verification Method for Trainer: listen for the start chime.
• Stop Video
  • Voice Command Syntax: "Hey Meta, stop recording."
  • Physical Shortcut Interaction: press the top capture button again.
  • Verification Method for Trainer: listen for the distinct trailing termination chime.
• Volume Adjustment
  • Voice Command Syntax: "Hey Meta, increase volume."
  • Physical Shortcut Interaction: swipe forward or backward on the right touchpad.
  • Verification Method for Trainer: instruct the client to verbally confirm the level change.
• Audio Play / Pause
  • Voice Command Syntax: "Hey Meta, pause." / "play"
  • Physical Shortcut Interaction: tap once directly on the lateral right touchpad.
  • Verification Method for Trainer: observe the audio state switch.
• Distance Units
  • Voice Command Syntax: "Hey Meta, use feet instead of meters."
  • Physical Shortcut Interaction: N/A (system configuration).
  • Verification Method for Trainer: ask the client to prompt a spatial check to verify unit changes. Please note: this feature should act as a complement to existing accessibility tools, such as a cane or service dog, not a replacement for them.

• Contextual Awareness: Instruct clients to power off the device via the left temple switch when entering sensitive environments.
• Bystander Transparency: Explain the “capture LED” function. Teach the client that the white LED indicates recording and that they should demonstrate this light to others to build trust and social transparency.
• Data Stewardship: See Module 1 for this step.
• Operating Safely: Remind the client to maintain spatial awareness when using the features.

• The Sharing Sequence: During a live video call on Messenger or WhatsApp initiated via the glasses, instruct the client to perform a physical double-press on the top capture button.
• Virtual Observation: If the client is calling you directly on WhatsApp to test this, verify that their video feed transitions smoothly from their smartphone's stationary front camera to a live, first-person point-of-view tracking shot originating from the glasses frames.
• Hands-Free Screen Locking: Instruct the client to hit the physical power button on their smartphone to lock the screen. Verify that the video streaming feed from the glasses continues uninterrupted while the phone remains closed and put away.

If the device becomes completely unresponsive and app connectivity is lost, the trainer must guide the client through a hardware button override. Because this process relies on timed button holds and a visual orange LED light, you must coach the client through these precise tactile movements:

1. Instruct the client to keep the glasses turned on.
2. Tell them to take the glasses off and fold the right temple arm completely closed while keeping the left arm open.
3. Instruct them to find the top capture button with their index finger.
4. Have them press the capture button rapidly 5 times in a row, and tell them to hold the button down firmly on the 5th press.
5. Trainer Visual Check: Look closely at the client's glasses. The small LED indicator on the inside of the frame will turn a solid orange color.
6. Tell the client: "The light is solid orange. Now, let go of the button and immediately press and hold it down again."
7. Keep them holding until you see the LED begin to flash orange. Tell them to release the button.
8. Inform the client that the reset is running while the light flashes orange and white. Once the LED flashes green and turns completely off, tell them the factory reset is complete.
9. Instruct the client to open their phone's Bluetooth menu via their screen reader and select Forget Device to clear out the old connection profile.

• Visual Fit Evaluation: Have the client turn so you can check how the frames fit:
  • Stability Anchoring: If the frames slip forward, instruct them to install silicone ear hooks onto the ends of the temple tips to anchor the glasses securely behind their ears.
