Display

Display — Eyes & Info

Quick Start

Controls the device's display. Two modes: animated eyes (default) and info text. Usually auto-synced by the Emotion skill — only call directly for manual eye control or info display.

Workflow

1. Determine the mode needed:
   • Eyes: [HW:/display/eyes:{"expression":"happy","pupil_x":0.0,"pupil_y":0.0}]
   • Info: [HW:/display/info:{"text":"14:30","subtitle":"Good afternoon"}]
   • Return to eyes: [HW:/display/eyes-mode:{}] when the info display is no longer needed, not immediately after the info marker.
2. Place markers at start of reply — the device fires them before TTS. Skip silently if display unavailable.

Important: The Emotion skill auto-syncs eyes during conversation. Do not call both Emotion and Display for the same reaction.

Examples

Input: "Look to the left" Output: [HW:/display/eyes:{"expression":"neutral","pupil_x":-1.0,"pupil_y":0.0}] (no confirmation needed)

Input: "What time is it?" Output: [HW:/display/info:{"text":"14:30","subtitle":"Good afternoon"}] It's 2:30 PM.

Input: "Show me a happy face" Output: [HW:/display/eyes:{"expression":"happy"}] Here's a happy face!

How to Control Display

No exec/curl needed for the display action. Choose the relevant inline marker below; these are separate actions, not a sequence:

[HW:/display/eyes:{"expression":"happy","pupil_x":0.0,"pupil_y":0.0}]
[HW:/display/info:{"text":"14:30","subtitle":"Good afternoon"}]
[HW:/display/eyes-mode:{}]

• pupil_x: -1.0 (look left) to 1.0 (look right)
• pupil_y: -1.0 (look up) to 1.0 (look down)
• text: max 20 characters, subtitle: optional max 40 characters

Available expressions

Error Handling

• If GET /display returns unavailable or the API is unreachable, skip all display calls silently. Do not error out to the user.
• If an invalid expression is given, fall back to neutral.
• If text exceeds character limits, truncate gracefully.

Rules

• Emotion skill auto-syncs eyes — when you call POST /emotion, the display updates automatically. Do not call both.
• Info mode has no automatic timeout. Do not chain eyes-mode immediately after info; it would erase the text before it can be read. Return to eyes when the user dismisses the info or a subsequent eye/emotion action takes over.
• The display is plugin hardware — it may not be available. Always check first, and skip silently if absent.
• Do not use this skill for normal conversation reactions — use the Emotion skill instead.

Output Template

[HW:/display/eyes:{"expression":"happy"}] Here's a happy face!

For info, use the display/info marker with the actual requested text instead. If the display is unavailable, skip the marker silently.
