The invention discloses an information output method and device. The method comprises the steps that three-dimensional trace of at least one stroke in three-dimensional space is obtained; orthogonal projection is conducted on the three-dimensional trace with the direction of a vision vector as the axis to obtain the projection result of the stroke in a two-dimensional projection plane, wherein the projection result comprises a stroke vector of the stroke in the two-dimensional projection plane; the projection result is compared with a preset literal pool, and the information matched with the projection result is output. The method and device solve the technical problem of inconvenient typewriting caused by three-dimensional hand output and recognition in the prior art.
