Electronic assessment of playing surface properties

A method, comprising:

• recording a trajectory of a ball launched onto a surface;
• extracting ball movement information from the recording;
• determining a 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 surface property is a coefficient of friction, a horizontal surface drag, a coefficient of restitution, or a deviation angle;
• and
• transmitting, for display on a display device, the surface property.

A method of assessing properties of a surface, 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 causing ball movement across the surface;
• recording a trajectory of the ball movement across the surface;
• determining whether the user properly performed the action based on detecting expected ball movement information;
• extracting ball movement information from the recording of the trajectory when the trajectory meets the expected ball movement information;
• determining properties of the surface from the ball movement information, wherein the properties include a coefficient of friction, a horizontal surface drag, a coefficient of restitution, a deviation angle, or a combination thereof;
• and
• conveying, for display on the display device, the properties.
