Activity scene detection, display, and enhancement implementations are described. In an example implementation, a method includes displaying an animated character on a display of a computing device, detecting a tangible interface object on a physical activity scene proximate to the computing device, rendering a virtual interface object based on the tangible interface object, determining an interaction routine between the animated character and the virtual interface object, and executing the animation routine to animate on the display, an interaction between the animated character and the virtual interface object.

A display device includes a display panel, a cover glass disposed on the display panel, and a biometric sensor device disposed below the display panel. The biometric sensor device includes a printed circuit board, a biometric sensor disposed on the printed circuit board, and a housing disposed on the printed circuit board and in which an opening is formed. The biometric sensor is disposed in the opening of the housing and is attached to a surface of the display panel through the housing.
