1. A detection processing device comprising:
a memory storing a program, and
at least one processor configured to execute the program to perform operations comprising:
receiving shape detection information that is information obtained by capturing a shape of a hand of a user in at least two dimensions; and
detecting a motion of the hand including a presence or an absence of contact between fingertips of the user on a basis of the shape detection information,
wherein detecting the motion of the hand comprises detecting a plurality of different combinations of a thumb and a plurality of other fingertips of the hand that are in contact with each other per unit time and detecting palm center position information.
