Abstract
A user interface device for detecting an operation, by a finger of a user, on an operation member presented on a projection surface includes a distance detector for detecting a distance to the projection surface, and a distance to the finger, and a controller for detecting the operation based on the distances detected by the distance detector. When presence of the finger between the projection surface and the distance detector is determined, the controller calculates a normal vector of the projection surface based on distances from the distance detector to positions of at least three points on a surface of the projection surface and a distance from the distance detector to the finger, and detects, based on the normal vector, presence or absence of an operation on the operation member.
