An image of the villi can be displayed on the display.

In addition, when the processing unit 110 performs an operation of enlarging or reducing at least a part of the object, the processing unit 110 may perform image enlargement by skipping at least one step.

For example, the stomach, small intestine, and large intestine constituting the digestive system are components, and the villi constituting the stomach have a first depth sub-element, and the cells, nerves, blood vessels, etc. constituting the villi have a second depth. It can be assumed as a sub-element.

In this case, the processing unit 110 may skip the first depth sub-element from the image displaying the component based on the control input and enlarge the image to the image displaying the second depth sub-element.

The processing unit 110 may process the reduction of the object based on the control input. For example, it is possible to check the control input for selecting and enlarging the villi while the image of the villi included above is displayed on the display as an object.

For example, the processing unit 110 may determine the search depth based on at least one of a level for a lecture class and a lecture progress. For example, in retrieving information related to the first component, when the first related information related to the first component is defined as the first search depth, the second related information related to the first related information is searched for a second time depth can be defined.

Here, the input of the instructor's text identified through the display is selected from among the text inputted by touch on the display of the electronic device 100, the text inputted through an input unit such as a keyboard, and the text inputted to the external display (eg, the instructor's writing). It may include at least a portion.

In addition, the processing unit 110 may search for and acquire related information based on the instructor's voice recognized through artificial intelligence technology. For example, when a designated word such as "search" is identified from the instructor's voice, the processing unit 110 may search for information related to at least some of the before/after designated words.

When the processing unit 110 searches for the second related information related to the first related information, the first component and the first related information are combined by considering the relevance of the first component in order to maintain the consistency of the related information. The related second related information may be searched.
