An input device for interacting with a display surface of an electronic display system. The input device can comprise a body, a nib, a sensing system, a cap, and a mode-indicating system. The body can provide structural support for the input device. The nib, which is in communication with the body, can be used to directly interact with the display surface. The sensing system can sense indicia of a posture of the input device with respect to the display surface to facilitate operation of the input device. The cap is securable over the nib, and can be incorporated into the mode-indicating system. When the cap is secured over the nib, the input device can operate in a first operating mode, and when the cap is removed, the input device can operate in a second operating mode. |
