Abstract: A system and method for controlling and modifying a live presentation with a wearable computing device are disclosed. A server system receives a request to begin a presentation from a wearable computer system. The server system then transmits presentation data to a presentation device for display. While transmitting the presentation data to the presentation device for display, the system receives one or more presentation interactions. The system then transmits each interaction stored in the interaction queue to the presentation device.

Abstract: The disclosed embodiments relate to a system for tracking and analyzing user interactions with a mobile user interface (UI). During operation, the system collects data while a user interacts with the mobile UI through a touchscreen, wherein the data includes tap-attempt data that specifies coordinates for touchscreen locations that the user has tapped while interacting with the mobile UI. Next, the system compares the tap-attempt data with locations of tappable elements in the mobile UI, wherein each tappable element has an associated tap target size. For each tappable element, the system uses results of the comparison to determine a percentage of tap attempts that have succeeded or failed for the associated tap target size. Finally, the system makes the percentage information available to a UI designer to enable the UI designer to adjust tap target sizes for the mobile UI.

Abstract: Apparatus and methods are provided for gravity-based access control. An apparatus may be secured with a gravity-based password that reflects a pattern of manipulation or movement of the apparatus. As the apparatus is moved or reoriented, data produced by a sensor (e.g., an accelerometer, a gyroscope, a position sensor) is assembled to form the password. Elements of the password may identify surfaces of the apparatus as it is flipped or placed in different orientations, or may represent the received sensor data (e.g., acceleration force of gravity, displacement). The sensor data may be multi-dimensional. A target or model password is received and saved, and a user must recreate or re-enter the same pattern in order to unlock the device or otherwise make it available for use.
