FIELD: information technology.
SUBSTANCE: in response to an attempt to select a target displayed on a screen, a callout can be rendered in a non-occluded area of the screen, wherein the callout comprises a representation of an occluded area of the screen in a non-occluded area of the screen, the callout is rendered when it is determined based on interaction with the user that the area under the selection area is occluded, the callout is not rendered when it is determined that the area under the selection area is not occluded, and the interaction with the user involves touching the occluded area of the screen with the selection entity when attempting to select the target displayed on the screen under the selection entity; and determining that the area under the selection area is occluded if the selection entity is in contact with the display for more than a threshold time.
EFFECT: more accurate selection of small targets displayed on a touch screen, fewer errors caused by occlusion of these targets by the finger of the user.
