The order for the trackers is head, left hand, and right hand. Even though there are only 3 objects being tracked, the input to the “Trackers” variable in the “Set Tracking Objects” function must be a 6 item array of actors. Step 2 will utilize the “DeepMotion Avatar Character > Set Tracking Objects” function to have the head and hands follow the defined tracking objects. You can simply create the empty actors in the level and place them wherever, but it is probably preferential to place their initial positions to match the location of each body part they are going to be assigned to. Set the head and hand objects to be the trackers in the “Set Tracking Objects” function for the DeepMotion Avatar character.These will be referenced in the next step. Create the 3 objects to be used for tracking as empty actors in the level.Inside the level blueprint you will want to do two things: Once the DeepMotion Avatar character is in the level, you will want to create the head and hand game objects prior to opening up the level blueprint. The assigned game objects will be the VR game objects if VR-enabled 3PT is desired. Assigned game objects to these fields will have the respective parts of the Avatar character tracking them. In this script you will find the fields for “Head Target”, “L Hand Target”, and “R Hand Target”. On the humanoid controller there is a script called “tntHumanoidController”. avt file) game object, open it up, and click on the Humanoid Controller child. Once the DeepMotion Avatar character is brought into the scene, open up the parent game object, find the root (or simAvatarRoot if you imported an. The basic process involves taking your DeepMotion Avatar character and assigning 3 objects that the Avatar character controller will use to move the hands and head around. Setting up 3PT for your DeepMotion Avatar Character The DeepMotion Avatar 3PT system will use the position and rotation of these 3 devices as tracking points for the character’s head and hands to reference. Typical IK solutions use geometry to snap limbs into certain positions, while we will use physics and ID to fluidly move the Avatar’s limbs. VR rigs like the Vive or Oculus Rift with Touch Controllers have 3 tracked objects that the user controls for virtual interaction the head mounted display and the two controllers are 3 easy points for us to use for 3PT.

In this case the controlled object is the player character, and in general this is highly useful for full body motion reconstruction in virtual reality. Three point tracking (3PT from now on), is controlling a character or avatar in real-time using 3 controller points. DeepMotion Avatar is currently in closed alpha, and available to test for early adopters via this application. We will go over implementation for both Unity and Unreal.

This short blog is geared towards intermediate developers and will cover how to use our Avatar SDK in your own VR experience or game, focusing on 3 point configuration for content geared at standard home rigs (which typically include a headset and two hand controllers). Our physics-based solution uses an inverse dynamic algorithm, rather than inverse kinematics, and natural joint constraints to infer lifelike user movements and to handle collision detection. DeepMotion Avatar offers unprecedented full body locomotion for VR Avatars using 1-6 points of tracking. And some developers take on the arduous task of implementing a full-body IK solution (typically using Final IK or IKinema), usually with blended animations to address strange limb rotations in areas like the elbow, as well as basic lower body movements. Larger companies focused on social experiences, like Facebook Spaces or the Oculus Avatar SDK, go a step further with upper-body representation. Simple solutions for user representation include floating hands or floating representations of hand controllers. Rather than looking at the far stretches of their new universe, users seem to have an innate concern with their own physicality. Anyone who has helped run a VR experience will note that one of the first things many people do when entering VR is to look down towards their feet. A cornerstone issue standing in the way of presence is embodiment. Virtual Reality is still in its infancy, with major challenges standing in the way of mass adoption, as well as what many consider the medium’s ultimate value proposition: to give users a sense of “ presence”, the feeling of being fully transposed and immersed in an interactive, virtual world.
