touchless

"Touchless" is a Python library for creating spatial interfaces without physical contact, using gestures, eye tracking, and voice commands. It enables developers to build immersive 3D UIs for VR/AR and beyond, with advanced gesture and voice recognition technology.

Environment Setup

python3 -m venv .venv
echo "export PYTHONPATH=$PWD" >> .venv/bin/activate
source .venv/bin/activate
pip3 install -r requirements.txt

Demo scripts

Demo for all gestures

python examples/demo.py

Description: print (in OpenCV window) all detected gestures

Turn on/off video stream output and blur

python examples/turn_on_off_and_blur.py

Recognized hand gestures:

Gesture Action
Hand down Turn off video output
Hand up Turn on video output
Three fingers Turn on blur
Two fingers Turn off blur

Select shape

python examples/select_shape.py

Description:

  • pointer is the index finger TIP
  • if the pointer is over a shape then the shape will be selected

Select shape with pointer mapping from the specific region

python examples/select_shape_map_pointer.py

Description:

  • pointer is the index finger TIP
  • if the pointer inside the center box then it will be mapped to pointer which can select shapes

Calculate angle

python examples/calc_angle.py [-x <x-coord>, [-y <y-coord>]]

where: -x and -y are user defined coordinates of an angle vertex; by default x, y = frame_width // 2, 0.

Description:

  • pointer is the index finger TIP
  • the first side of an angle is a vertical line - from vertex to bottom
  • the second side is a line connected angle vertex with the pointer
  • if the pointer detected then:
    • the second angle side will be drawn
    • the angle value (in degrees) will be calculated

Triangle by points of wrist and index and pinky fingers MCP

python examples/triangle_0_5_17_area.py [--width <frame_width> [--height <frame_height>]]

Calculates:

  • the triangle area (in pixels)
  • a distance to a camera (approximately)
  • angle between the triangle and camera by z-axis

Note: the distance to a camera is calculated with assuming a palm (the triangle) is parallel (as well as possible) to the camera; for now the angle by z-axis is not considered.

Multiple hands using GestureProvider

python examples/multiple_hands.py

Description: detects all hands and gestures by its point, outputs detected gesture for each hand.
