More realistic experiences can be provided to a user through the use of a wearable suit. The xR wearable suit may include materials with adjustable characteristics, such as friction, and electronics for controlling the materials to provide feedback to the user wearing the xR suit. In an xR game, the materials may be used to translate virtual damage to physical constraints on the user. For example, when an avatar gets shot in the leg and is debilitated, the user's leg motion can be constricted to understand that shortcoming and stay in sync with the avatar. Examples of such feedback materials include inflating ribs, sheet jamming, and mechanical devices.

Systems and methods are provided for facilitating computer vision tasks (e.g., simultaneous location and mapping) and pass-through imaging include a head-mounted display (HMD) that includes a first set of one or more cameras configured for performing computer vision tasks and a second set of one or more cameras configured for capturing image data of an environment for projection to a user of the HMD. The first set of one or more cameras is configured to detect at least a visible spectrum light and at least a particular band of wavelengths of infrared (IR) light. The second set of one or more cameras includes one or more detachable IR filters configured to attenuate IR light, including at least a portion of the particular band of wavelengths of IR light.

An electronic device, while the electronic device is worn over a predefined portion of the user's body, displays, via a display generation component arranged on the electronic device opposite the predefined portion of the user's body, a graphical representation of an exterior view of a body part that corresponds to the predefined portion of the user's body. The electronic device detects a change in position of the electronic device with respect to the predefined portion of the user's body.
