In one implementation, a method of displaying content is performed at a device including a display, one or more processors, and non-transitory memory. The method includes scanning a first physical environment to detect a first physical object in the first physical environment and a second physical object in the first physical environment, wherein the first physical object meets at least one first object criterion and the second physical object meets at least one second object criterion. The method includes displaying, in association with the first physical environment, a virtual object moving along a first path from the first physical object to the second physical object. The method includes scanning a second physical environment to detect a third physical object in the second physical environment and a fourth physical object in the second physical environment, wherein the third physical object meets the at least one first object criterion and the fourth physical object meets the at least one second object criterion. The method includes displaying, in association with the second physical environment, the virtual object moving along a second path from the third physical object to the fourth physical object, wherein the second path is different than the first path.

Disclosed is a real-scale landslide simulator for earthquake reproduction comprising: a base; a tower provided in one end of the base; a multi-stage simulation soil box provided movably in the vertical direction along the tower and filled with soil, which is subjected to compaction; a movable bogie provided movably in the horizontal direction on the upper surface of the base while supporting the other side of the multi-stage simulation soil box; a vertical reciprocator that reciprocates the multi-stage simulation soil box in the vertical direction; and a horizontal reciprocator that reciprocates the movable bogie in the horizontal direction. It is possible to reproduce liquefaction and shear strength reduction caused by an earthquake and analyze a real-scale landslide mechanism caused by an earthquake by repeatedly providing vertical and horizontal vibrations to the soil and forming a groundwater level using the groundwater simulation device.

A tree cutting training assembly and method including an elongated pole member defining a longitudinal axis. The elongated pole member may be unitarily formed or may be formed with separate base and body portions removably coupled to one another via a coupling member. The elongated pole member may include a plurality of removable branch members. A base member is provided that is configured and operable to removably secure a base portion of the elongated pole member to the ground plane, such that the elongate pole member upstands at an angle from the ground plane to facilitate tree/pole felling/cutting training exercises. The base member may be configured to pivot between first and second positions, wherein the first position disposes the secured elongated pole member substantially parallel to a ground plane and the second position disposes the secured elongated pole member at an angle relative to the ground plane.

The systems and applications for generating the augmented reality (AR) images are disclosed. The system includes a processing module and a digital microscope module having a plurality of camera units, and the processing module tracks and parses the user's motions to generate the related control signals, the virtual objects composed to form the AR images according to the received instant images of the observed objects captured by the digital microscope module. Moreover, the processing module generates and outputs the AR images composing of the instant images and the user interface (UI), icons, objects, video and/or information related to the interactive applications while the display mode switch or the real-time tutorial and sharing is triggered.

An artificial cave has various features that resemble speleothems (e.g., stalactites, stalagmites, etc.) found in real subterranean caves. Human users may pass through the artificial cave, with each user wearing a wearable transceiver that broadcasts a signal code unique to that user. Fixed transceivers throughout the cave can detect and identify any user who is sufficiently close to that fixed transceiver. Other components of the system collect user identification information from the fixed transceivers for any of several possible purposes (e.g., identifying which user was probably responsible for inappropriate interaction with a speleothem that is adjacent to a given fixed transceiver, where all of the various user of the cave are currently located in the cave, etc.). A count of users currently in the artificial cave passageway may be maintained and used for a number of purposes. Similarly, human detectors may be employed near the system and/or in the artificial cave passage for any of several different purposes.
