<p>There have been a variety of attempts to make light-emitting display sticks, used when directing traffic at night, cheering at various events, and the like, that not only simply emit light but take advantage of persistence of vision to display letters or patterns in space. However, depending on the manner in which and speed at which the stick is waved, said letters or patterns become distorted and unrecognisable. In light of this problem, the issue is to implement a might-emitting display stick that both is suited to cheering at and can display easily recognisable letters in space regardless of the manner in which and speed at which the stick is waved. The light-emitting display stick in the present invention contains an internal waving-angle sensor and can display undistorted letters or patterns in space by having light-emitting emit light in accordance with waving-angle information indicating angles with respect to a base angle. Said light-emitting display stick can also switch to a mode in which all of the light-emitting emit light. Said light-emitting display stick is thus easier to use and more effective.</p> |
