Technologies for displaying supplemental interface tiles on a user interface of a computing device include determining supplemental information and/or available user interactions associated with a user interface tile displayed on the user interface. A supplemental interface tile is displayed in association with the user interface tile in response to a user selecting the user interface tile. The supplemental information and/or an interaction widget corresponding to the available user interactions may be displayed on the supplemental interface tile based on the selection gesture used by the user to select the user interface tile.
