Abstract
A method at a computer system includes obtaining an electronic document comprising document elements, and injecting into the document in association with one of the document elements one or more hotspot attributes, the hotspot attributes defining attributes of a hotspot that is displayable in conjunction with the document element when the document is displayed, the hotspot attributes being associated with predefined physical gestures and respective document actions; such that the hotspot, when displayed as part of a displayed document, indicates that a viewer of the displayed document can interact with the displayed document using the predefined physical gestures (i) performed at a position that overlap a displayed version of the document in a field of view of a camera system and (ii) captured by the camera system, wherein a physical gesture results in a respective document action being performed on the displayed document.
