  • the head-mounted display testing system may include a ride motion simulator that includes an actuator and a robotic arm attached to a mount.
  • the mount receives and retains the head-mounted display during testing.
  • the mount may be generally sized and shaped to resemble a human head.

For example, if the marker is detected but no displayed image is detected on the screen of the head-mounted display, this indicates that the screen of the head-mounted display may be broken or otherwise compromised. If neither the displayed image nor the marker is detected, the head-mounted display may have shifted or fallen off the mount. If the displayed images are detected but deviate from corresponding expected images (e.g., stored reference images), the head-mounted display can be flagged as nonoperational. Conversely, correspondence of the detected displayed images with expected images can be used to mark the head-mounted display as operating normally. Flagged head-mounted displays can be further evaluated to identify a failure mode and/or for maintenance or cable replacement.
  • This operational state may be used to determine parameters such as the average lifetime (e.g., number of ride cycles before image quality is compromised) of a headmounted display in an amusement park environment. Further, by testing different ride motion patterns, particular patterns may be identified as being associated with shorter use lifespans. Thus, future amusement rides using head-mounted displays can be designed to include less disruptive motion patterns and to avoid motion patterns associated with head-mounted display malfunction and shorter lifespans.

  • the memory device(s) 94 may store machine-readable and/or processor executable instructions for the ride motion pattern execution.
  • the processor(s) 92 may execute software programs and/or instructions to direct the movement of the robotic arm 34 and the actuator 44 to move the mount 36 according to a motion pattern.
  • the controller 96 receives the footage captured by the camera(s) 40 for processing (e.g., image detection).
  • the controller 96 includes processor(s) 98, memory device(s) 100, an input/output (I/O) port 102, and a user interface 104.
  • the I/O port 102 may receive the footage from the camera(s) 40.
  • the processor(s) 98 may execute software programs and/or instructions to receive the signal from the one or more camera(s) 40 and to identify deviations from an expected display on the display screen 52 based on the signal. For example, a processor 98 may run an image recognition algorithm to identify the displayed image 54 and the marker 56 on the display screen 52.
  • the memory device(s) 100 may include one or more storage devices and may store machine-readable and/or processor-executable instructions (e.g., firmware or software) for the processor(s) 98 to execute, such as instructions relating to receiving camera signal and identifying deviations from an expected display.
  • the controller 96 may thus generate an indication of the head-mounted display quality based on the identified deviations.
  • the user interface 104 may be used to configure the controller 96 for processing the camera signal.
  • GUI graphical user interface
  • the user interface 104 may be used to set the expected display (e.g., expected image 54 and marker 56) so that deviations from the expected display can be identified in the detected images (e.g., detected image 54 and marker 56), as described in block 68.
  • the user interface 104 may be used to communicate the indication of the head-mounted display quality to the users.
  • the user interface 104 may display a notification indicating that the head-mounted display 26 is malfunctioning.
  • the user interface 104 may display a notification indicating that a head-mounted display 26 is on the ride motion simulator 12 prior to the beginning of the head-mounted display testing.
  • the head-mounted display 26 can display images that are provided to the controller 74 of the head-mounted display 26 via the cable 30. These images may be provided as reference images 110 to the controller 96 and used to identify deviations. For example, the reference images 110 can be compared to the captured images from the camera(s) 40. If the head-mounted display is operating as intended, the images displayed on the display screen 52 of the head-mounted display 26 and captured by the camera(s) 40 should have high conformance to the reference images 110.

Abstract

Un système de test de visiocasque peut comprendre un simulateur de mouvement de manège servant à simuler un mouvement d'un manège ainsi qu'un visiocasque qui est installé sur le simulateur de mouvement de manège et qui affiche une image virtuelle. Le simulateur de mouvement de manège comprend une ou plusieurs caméras orientées vers l'extérieur qui sont conçues pour capturer l'image virtuelle et un marqueur physique lorsque le visiocasque se trouve sur le simulateur de mouvement de manège. Le dispositif de commande est conçu pour recevoir le contenu de l'écran de visiocasque capturé par la ou les caméras et pour générer une indication de qualité de visiocasque sur la base d'écarts par rapport à un affichage attendu.
