A touch-sensitive display (12) system (10) includes a display (12), a contact detection means (20), and a hover detection means (26). The display (12) is configured to display (12) an image (16, 116, 216) toward a surface (14) of the display (12). The contact detection means (20) is configured to determine a contact location (22) on the surface (14) indicative of where a finger (18) contacts the surface (14). The user input is determined based on content of the image (116) at the contact location (22). The hover detection means (26) is configured to determine a hover location (28) of the finger (18) relative to the surface (14) when the finger (18) is within a hover distance (30) of the surface (14). The system (10) is further configured to magnify a selected portion (32, 132, 232) of the image (16, 116, 216) that corresponds to the hover location (28). |
