Disclosed are systems, methods, and devices for interfacing with a wearable heads-up display via a touch-operable input device. The wearable heads-up display may include a display element for receiving and displaying display information received from a processor, and may also include a wearable frame structure supporting the display element and having a side-arm extending away from the display element. In some embodiments, the display information may appear at least partially curved to a user. In some embodiments, only a portion of the display information is shown on the at least one display element. The side-arm may be configured to secure the heads-up display to a user's body in a manner such that the display element is disposed within a field of view of the user. The touch-operable input device secured to the wearable frame structure is configured to sense at least one of a position and movement of a touch or finger along a planar direction relative to a surface of the input device, and to provide corresponding input information to the processor. A navigation tool may also be displayed on the at least one display element for indicating the location of the touch on the touch-operable input device.
