AR Projection Simulator is an app that allows you to simulate the installation of a projector using AR. You can visualize the relationship between the projector installation position and the projection size, and explore the possibilities of spatial effects created by Z-projectors. It can be used for preliminary design and creating proposal images for customers. 【Features】 1. Reproduces the various installation methods that are the greatest feature of the Z Series. You can simply select from a list to display the abundant installation methods achieved through two-axial rotatable lens and vertical/horizontal installation. 2. Easily simulate the demo of overhead installation, which is hard to do with actual equipment. You can easily visualize the hanging height required to obtain the desired projection size. It also allows simulation of the height of overhead mounting brackets or stands. 3. Compare various projectors and installation positions/projection ranges. By entering the specifications, you can register and simulate various models. 【Supported OS】 iOS 16.6 or later iPadOS 16.6 or later 【Supported Devices】 iPhone SE (2nd generation), iPhone 8 or later iPad Pro 12.9-inch (1st generation) or later iPad Pro 11-inch (1st generation) or later iPad Pro 10.5-inch iPad Pro 9.7-inch iPad (5th generation) or later iPad mini (5th generation) or later iPad Air (3rd generation) or later For simulations in environments with less features, such as plain walls, we recommend using a device with LiDAR. 【Notes】 This simulator is a convenient tool for estimation only. It is not intended to provide exact measurements. There may be a few % differences from the actual measurements. Depending on the pose of the projector, shadows may occur due to the main unit being between the lens and the screen.
