## What is Spatial Sketcher?

Spatial Sketcher is a dual-tool research application designed for educators, researchers, and spatial analysts. Capture detailed floor plans using LiDAR technology and transcribe audio with precise timestamps. All optimized for educational research workflows.

Room Scanner

  • Generate high-resolution floor plans (3000px) from LiDAR scans
  • Automatic detection of walls, doors, windows, and furniture
  • Smart rotation aligns floor plans to the longest wall
  • Color-coded visualization: walls, doorways, windows, and 15+ furniture types
  • Export as PNG, JPG, or USDZ 3D models
  • Includes scale metadata with pixels-per-meter conversion for overlay analysis

Transcription Tool

  • Import audio (MP3, M4A, WAV, AAC) or video (MP4, MOV, M4V)
  • Record directly within the app with real-time waveform display
  • Time-stamped transcription segments with confidence scores
  • Speaker identification for multi-person conversations
  • Adjustable pause detection (0.5–5 seconds) and segment length (5–30 seconds)
  • Support for 50+ languages
  • Export as CSV for data analysis or TXT for readability

Built for research

Spatial Sketcher was developed as part of PhD research on teacher movement and classroom interaction.

The app produces datasets ready for:

  • Spatial visualization tools (IGS compatible)
  • Movement pattern analysis
  • Discourse analysis
  • Mixed-methods research combining spatial and temporal data

Export & Share

Share your data via AirDrop, Files, email, or any compatible app. Floor plans include detailed scale metadata for accurate real-world coordinate mapping.

Requirements

  • Room Scanner requires iPhone 12 Pro+ or iPad Pro 2020+ with LiDAR
  • Transcription works on any device running iOS 17+
  • Camera, microphone, and speech recognition permissions required

Privacy-focused: On-device transcription available with optional cloud processing for enhanced accuracy.
