Electronic assessment of playing surface properties

A method, comprising:

• detecting a ball shot onto a playing surface by a ball launcher;
• triggering recording of the ball by a camera in response to detecting the ball shot onto the playing surface;
• extracting ball movement information from the recording;
• determining a playing surface property from the ball movement information based on the extracted ball movement information and comparison of the extracted ball movement information with expected ball movement information generated based on predetermined test conditions, wherein the playing surface property is a coefficient of friction, a coefficient of restitution, or a deviation angle;
• and
• transmitting, for display on a display device, the playing surface property.

A method of assessing properties of a field, comprising:

• executing, on a processor, instructions that cause the processor to perform operations comprising:
• conveying, for display on a display device, user instructions requesting a user perform an action on the field;
• operating a camera to generate a recording of ball movement;
• determining if the user performed the action based on the recording;
• conveying, for display on the display device, adjusted user instructions when the user did not properly perform the action;
• extracting ball movement information from the recording when the user did properly perform the action;
• determining properties of the field from the ball movement information, wherein the properties include a coefficient of friction, a coefficient of restitution, a deviation angle, or a combination thereof, and
• conveying, for display on the display device, the properties.
