Pixilab - Block license: Locator

The Locator block is used to determine the visitor's current location in an exhibit, installation, or venue — in order to present location-specific content. It doesn’t show content by itself but triggers other blocks (typically Spot-related content).

NOTE: This is a premium feature — you’ll need an additional license to use it.

Location Detection Methods

Visitors can be located using several methods (you can enable multiple options):

1. Numeric Keypad
   User enters a number corresponding to a Location ID shown at the physical spot.

2. GPS (Geolocation)
   Matches current GPS position to a geofenced Spot. Requires an HTTPS connection and a GPS-capable device (e.g., smartphone). Works best outdoors.

3. QR Code Scanning
   Uses device camera to scan a QR code linked to a specific Spot. Also requires HTTPS.

4. NFC Tag Scanning
   Tap an NFC tag to trigger a Spot location. Requires HTTPS and is more limited on iOS (must open Safari).

5. RFID/Keyboard Emulation
   External hardware (e.g., Zebra scanner) types the Location ID and presses "Enter" as if using a keyboard.

6. Manual On-Screen Button
   For example, touch an object on-screen to locate it.

Visitor Experience Flow

1. The user interacts with the Locator (via keypad, GPS, QR, etc.).

2. The corresponding Spot block is shown (could be image, video, audio, or a whole multi-page guide).

3. When playback ends, the Locator can auto-return to the keypad/menu — or remain, based on settings.

4. A back button is available (unless disabled) to return manually.

Key Settings

• Location Methods: Choose which detection methods are available.

• Back Button at Location:

  • Close Location: Immediate return to keypad/menu.

  • Go Back: Like browser back — navigates step-by-step.

  • Not Shown: Use a custom button to close.

• Auto-close when Playback Stops: Locator returns to idle view after playback, with optional delay.

• Geolocation Performance: Balance accuracy vs. speed (e.g., "Most Accurate" vs. "Balanced").

• Optional Binding: Bind the current Spot info to a variable (boolean, number, or string) — useful for advanced scripting or interactivity.

Composability

• A Locator can live inside other blocks like Book, Stack, or Composition, enabling multi-level, multi-language, or themed guides.

• You can hide the numeric keypad if not needed, e.g., when using programmatic or button-triggered location detection.

Dual Use: Display + Visitor

If you want the same content to appear on both Display and Visitor spots, use:

• A Synchronizer or Tag Selector as the top-level block.

• Child blocks tagged appropriately (e.g., “mobile” for visitors).

Important HTTPS Notes

• GPS, QR, and NFC modes only work over HTTPS.

• Requires a valid SSL certificate.

• User interaction is always needed to trigger these modes (browser security requirement).
