Embodiment Construction

[0027] Embodiments of a system, user device, and method are described that implement relative inertial measurement techniques to determine relative motion of a user or a portion of a user's body relative to a non-fixed frame of reference, such as a vehicle in which the user is traveling. In some implementations, relative inertial measurement techniques may be used to determine images to be displayed to a user via a head-mounted display based on the relative motion of the user's head while the user is traveling in a non-fixed frame of reference, such as a vehicle. In some implementations, relative inertial measurement techniques may be used with a controller coupled to the user's body to determine the motion of the user's body relative to the motion of a non-fixed frame of reference in which the user is traveling, such as a moving vehicle.

[0028] In some embodiments, the relative inertial measurement system includes at least two inertial measurement devices. The first inertia...

Abstract

Methods and systems for relative inertial measurements may include a user device configured to couple with a user's body and measure motion of the user's body or a portion of the user's body while the user is seated in a vehicle. The second inertial measurement device may be configured to move with the vehicle, but not with movement of the user's body within the vehicle. One or more processors may receive inertial measurements from the first inertial measurement device and the second inertial measurement device, and determine the user's body or the user's body by comparing the received inertial measurements. movement of the portion relative to the vehicle.

Description

Background technique [0001] Virtual reality (VR) allows a user to experience and / or interact with an immersive simulated environment, thereby making the user feel as if they were there. For example, a virtual reality system can display a stereoscopic scene to a user to create an illusion of depth, and a computer can adjust scene content in real time to give the illusion that the user is moving within the scene. Thus, when a user views an image through a virtual reality system, the user can feel as if they are moving within the scene from a first-person perspective. Similarly, augmented reality (AR) combines computer-generated information with real-world imagery to enhance or add content to a user's view of the world. Accordingly, a simulated environment of virtual reality and / or augmented content of augmented reality can be used to provide an interactive user experience for a variety of applications, such as interacting with a virtual training environment, playing games, remo...
