Abstract: A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.

Abstract: An application for use with a mobile computing device is described that enables group members of a group activity to view the positions of each member in one or more formations for the group activity. The application enables the user to select a formation for viewing and practicing in any location, whether indoors or outdoors and with or without other group members of the group activity. The application allows the user to toggle between a top-down view and an augmented reality view. The augmented reality view enables a user to view graphical indicators of each position of the user, whereby the graphical indicators are superimposed on a user's computing device in the real user environment. The augmented reality view provides a user with a better understanding of his or her positions in a real-world environment.
