Magic Leap 1 (ML1) is an augmented reality headset from Magic Leap.

There are two main versions, called Magic Leap One Creator Edition, and Magic Leap 1.

It uses diffractive waveguides for its displays.[1] It has a field of view of about 50 degrees (40 wide by 30 tall).[2]

The Magic Leap 1 blocks out most of the light from the outside world, so it is like wearing sunglasses.

It uses 3D tracking that is camera based and proprietary. It uses emitted IR for 3D tracking.[3]

A Magic Leap 1 system consists of three hardware components: The headset, the compute pack, and the controller.

The Magic Leap 1 headset receives DisplayPort data from the computer using a SlimPort ANX7530 4K DisplayPort receiver.[3] The ANX7530 splits the DisplayPort signal into two MIPI signals: one for each eye.[4]

Headset[edit]

The headset has a higher field of view than the HoloLens 1. The headset is referred to from Magic Leap as the "lightwear". The headset is hardwired into the attached computer.

Its display system uses OmniVision's OP02222 field-sequential color (FSC) LCOS modulator as the image source.[3] It is a type of spatial light modulator.

The Magic Leap was made in two sizes, called size 1 and size 2. Size 1 is for interpupillary distance (IPD) less than 65 millimeters. Size 2 is for IPD above 65mm.[5] The headsets came with a variety of forehead and nose pads in the box.

The headset has multiple sensors and at least six external cameras to gather spatial environmental data for egocentric tracking. The Magic Leap One has built-in speakers and built-in microphones, four of them in the headset. The speakers are low quality.

The headset uses a set of two switchable waveguide elements per eye, for two separate focal planes per eye that automatically switch based on eye tracking sensors embedded in the headset that detect if the user is focused near or far. It is meant to use eye tracking to determine where the user is roughly focusing, but it has problems.

Attached computer[edit]

There is an attached computer that Magic Leap named the lightpack.

The computer that powers the headset comes in the form of a compact disc-shaped hip-pack. The gadget comes with a clip-on mechanism to attach to the belt or shoulder pad and is tethered to the headset.

The main processor is an Nvidia Tegra X2.[6]

Controller[edit]

There is a handheld controller that has 3D tracking and buttons on it. It uses magnetic tracking. It is heavy.

The controller tracking is not good. It is worse than Polhemus systems.[7]

Software[edit]

The Magic Leap 1 runs Lumin OS and is generally locked down to it. The Magic Leap 1 is not made to be able to put a custom operating system on it.

Magic Leap primarily uses the handheld controller as input. The controller has a "home" button. There is a software keyboard operating by using the controller as a laser pointer.

If the ML1 loses tracking, it will display an interface in 2D with no 3D tracking.

SDK[edit]

The Magic Leap SDK was announced on June 2, 2015 during the MIT Technology Review’s EmTech Digital conference. The SDK is compatible with with both Unity and Unreal game engines. Sign-ups were available on its website.[8]

The graphics rendering on the ML1 cuts off anything closer than a foot to the user. Anything closer gets cut off. Magic Leap claims this is for comfort due to the vergence accommodation conflict.

The Magic leap can be used in a Unity 2018 development environment. Newer versions of unity have dropped support.

Magic leap Ones require remote software signing by Magic Leap. A device can be locked, which requires contacting Magic Leap's support to get an unlock code.

There is a program called mldb that runs on a computer that can connect to a Magic Leap 1 connected over USB.[9]

Applications[edit]

See List of Magic Leap applications.

There were apps available from an app store named Magic Leap World.[10]
