FindNode

Fresh

FindNode is Sigma RT's shell program that identifies UI elements through query-based interaction rather than coordinates. It integrates with Android Accessibility services to enable intelligent automation across devices with different resolutions.

Key Advantages

• No coordinate dependency — queries target UI elements by properties (text, ID, class)
• Cross-resolution — same queries work on any screen size
• Multi-device — run the same automation across different phone models

Core Components

Component	Purpose
Query Language	JSON-based syntax to locate UI elements
Selector	Core matching technology
Object Mode	Multi-device synchronization
UI Explorer	Visual tool for building queries
AAIS	Scripting language built on FindNode
REST/JS API	Programmatic access to FindNode

How It Works

Instead of clicking coordinates:

// Old way (coordinate-based)
device.click(540, 960);

// FindNode way (object-based)
device.sendAai({ query: "T:OK", action: "click" });

The query T:OK finds the element with text "OK" regardless of its position on screen.

Three Essential Tools

1. UI Explorer — Main pane > Scripts > Tools > UI Explorer. Inspect UI element properties and test queries visually
2. Terminal — Main pane > Scripts > Terminal. Interactive testing with sendAai() command
3. JavaScript (Rhino) — Combine queries and terminal tests into reusable scripts

SigmaTestApp

A dedicated test app is available to experiment with FindNode:

• Launch from Total Control menu
• Auto-installs on connected devices if not present
• Contains sample UI elements for query testing

Sections
