* when the touchActions are collected they are not a valid value, so we need to clean things up. * * @param {String} actions * @returns {*}

* extend the data with some usable properties like scale, rotate, velocity etc * @param {Object} manager * @param {Object} input

* velocity is calculated every x ms * @param {Object} session * @param {Object} input

* create new input type manager * called by the Manager constructor * @param {Hammer} manager * @returns {Input}

Convert cvimage into a pygame image

Draw on 'frame' pairs of keypoints

Draw on 'frame' pairs of keypoints

Draw drone moves

If in tracking mode and no body detected, the drone will try to find a body

* calculate the rotation degrees between two pointersets * @param {Array} start array of pointers * @param {Array} end array of pointers

* calculate the scale factor between two pointersets * no scale is 1, and goes down to 0 when pinched together, and bigger when pinched out

Get angle between two lines respective to 'posref' NOTE: using dot product calculation.

Both hands up - Check if both hands are on the ears

Define keys and add listener

Left ear and left hand on the same side

Check if we detect a pose in the body detected by MediaPipe

Right ear and right hand on the same side

handle the drone path drawing and drone path planning

Initiate the sound feedback

Calculate the brightness of a frame and returns True if the brightness is below 'threshold' (= pressing)

Main function mock_drone = False will use your computer camera enable_web = start a web server with streaming video and remote control enable

We are not flying, we check a potential morse code

Open the path planning screen for drawing the drone path

Tell drone to land

Populate neck and mid_hip points in the body

Call to pose detection

If we are doing a 360, where are we in our 360 ?

Set logging framework

Enable | Disable control by gesture

If in tracking mode, the drone will try to track the target

* trigger dom event * @param {String} event * @param {Object} data

Watch for drone moves
