holoscanners and projectors

Overview

holoscanners are a type of camera that can capture a 3D scan of an object or scene. They are fairly common devices on their own, but you can also frequently find them built into items such as a holowatch.

Holoprojectors are devices designed for viewing the 3D scans and projections. Simple versions are also built into holowatches, but they are commonly sold separately as well.

Uses

Holoprojectors are very popular, both as stand-alone devices or as a addition to other tools or appliances. Small versions are built into every holowatch and act as the display and UI of the device. These holodisplays are able to be directly interacted with and controlled by tracking the user's gestures. holowatches aren't the only devices that use them, many, many other household items, also feature holodisplays. Common uses include the display for computers, projected displays for holoscans, control panels for various items and appliances such as light switches, faucets, spacecraft and more.

Larger and higher quality holoprojectors can often be found in the living rooms of many Kepek as the centre-piece of many entertainment and gaming systems. Even larger and complex versions can be found in community centres and theatres, which are capable of displaying extremely lifelike 3D recordings for immersive viewing experiences.

Holoscanners on the other hand, while still very common, are not nearly as versatile. Simple scanners are included in every holowatch and some other portable devices such as personal drones, but the stand-alone version is far less common. Stand-alone holoscanners can produce far more realistic results, but tend to be rather costly.

Laws and Restrictions

There are not many laws on a galactic level surrounding the use and creation of holoscanners and holoprojectors - the few that do exist are mainly for the safety of the users.

Seizure and Migraine safety

Historically, low-quality holoprojectors would noticeably flicker, as the 3D images were created by rapidly flashing lights off of small, reflective particles held in place and moved as needed using magnetic levitation. This caused rapid decreases and increases in brightness throughout the projection, as well as random flickering or shifts in colour. This flicker was noticeable but bearable to most, but was extremely distressing or even dangerous to those with migraines, photosensitive epilepsy and some light-sensitive autistic kepek, causing the onset of migraines and even seizures. As a result, the Kepek Commonwealth put restrictions in place once they started becoming nearly unavoidable, that ensured all projectors were safe for Kepek with these and other similar disabilities to view. Now, holoprojectors create their projections using much more sophisticated methods that are extremely unlikely to cause seizures or migraines, but these laws remain to prevent anyone from potentially cutting those corners.

Likewise, holoscanners need to be able to create the projections without unnecessary or unintended flickering.
