Vision Tools

Vision-based automation tools for macOS. Enables LLMs to see and interact with the desktop through screenshots, OCR, mouse/keyboard control, and webcam capture.

Features

• Screenshot Capture: Full screen, app windows, regions, with coordinate grids
• OCR-Based Interaction: Click on text, read pages, find elements
• Mouse & Keyboard: Clicks, typing, key combos, scrolling
• Webcam with PTZ: Capture snapshots, control pan/tilt/zoom
• Game Controller: Vision-based autonomous gameplay

Quick Start

# Setup
./setup.sh

# Take a screenshot
./bin/screenshot.sh

# Read a webpage
./bin/interact.sh --in-app Firefox --read-page

# Click on text
./bin/interact.sh --in-app Firefox --click-text "Sign In"

# Take a webcam snapshot
./bin/snapshot.sh

Installation

Prerequisites

• macOS 12+ (uses Vision framework, Accessibility API)
• Python 3.11+
• Homebrew

Required Tools

brew install cliclick    # Mouse/keyboard automation
brew install ffmpeg      # Webcam capture

Optional Tools

npm install -g uvcc      # PTZ camera control (Insta360 Link 2)

Setup

./setup.sh

This creates a Python virtual environment and installs dependencies.

Permissions

macOS requires explicit permission grants:

Permission	Required By
Screen Recording	screenshot.sh, interact.sh, joystick.sh
Accessibility	interact.sh, joystick.sh
Camera	snapshot.sh

Check permission status:

./bin/permissions.sh

Interactive setup walkthrough:

./bin/permissions.sh --grant
# Or via setup.sh:
./setup.sh --permissions

Open all permission panes at once:

./bin/permissions.sh --open-all

Each tool also has --status to check its specific requirements:

./bin/screenshot.sh --status
./bin/interact.sh --status

Tools

Tool	Purpose
./bin/screenshot.sh	Desktop screenshots
./bin/interact.sh	Mouse, keyboard, OCR, app control
./bin/snapshot.sh	Webcam capture with PTZ
./bin/joystick.sh	Vision-based game controller
