Abstract: A method of authoring experiential learning content includes displaying an authoring window to author the experiential learning content when a request is made to author the experiential learning content; and creating a virtual world by loading and arranging 3D objects and a 2D objects, in the authoring window, which corresponds to a scenario of the experiential learning content. Further, the method includes defining an Action-zone that determines a position where a user is merged in the virtual world; and defining a state by dividing the scenario into a plurality of steps as time goes by based on the scenario to play the experiential learning content from a specific time point, respectively. Furthermore, the method includes defining a processing routine of an event occurred in the state; and authoring the experiential learning content according to the defined Action-zone, the defined state, and the defined processing routine.

Abstract: A method for recognizing markers printed on a learning material, includes sampling an image of the learning material; grouping the sampled image of pixels into a first image group and a second image group based on a threshold; and calculating medians of the first image group and the second image group to update the threshold with a first average value of the calculated medians. Further, the method for recognizing markers printed on the learning material includes repeating the above until a difference between a previous threshold and an updated threshold is equal to or smaller than a reference value; binarizing an image captured by a camera based on the updated threshold; and detecting the markers based on the binary image.
