2. Overview of the YEI 3-Space Mocap Studio
2.1 Introduction
The YEI 3-Space Mocap Studio is an open source motion capture application that uses the YEI 3-Space Sensor™
devices. The interface is similar to other motion capture applications (e.g. Blender), but is more convenient in
getting started with the 3-Space Sensor devices since the application was created for them. It automatically
searches for 3-Space Sensor devices already in use by the computer on start-up of the application. It can
import/export sessions of the whole application as our Three Space Hierarchy (TSH) that also stores information
of the 3-Space Sensor devices being used. However, it can only set-up and record motion data. It cannot edit or
clean-up the motion data like other motion capture applications. Do not sweat though, because the Mocap Studio
can also import/export motion data using the Biovision Hierarchy format (BVH), which is a widely used form for
motion capture data.
The Mocap Studio interfaces with the 3-Space Sensor devices through a Node Graph interface window which allows the
creation of complex node configurations to facilitate communication with 3-Space Sensor devices. Within this window,
you can edit the 3-Space Sensor device's settings and pair 3-Space Sensor Dongle devices with 3-Space Sensor Wireless
devices. The Node Graph Window can also manipulate the data coming from the 3-Space Sensor devices to allow
sensor re-targeting or other complex motion capture rigs. The Node Graph Window loads/saves its node configurations
as XML files.
2.2 System Requirements
Software:
• Windows XP (32-Bit), Windows Vista/7 (32-Bit or 64-Bit)
2.3 Key Features
The YEI 3-Space Mocap Studio has many features that allow it to be a flexible motion capture application for the
3-Space Sensor devices. Below are some of the key features:
• Supports all members of the YEI 3-Space Sensor family
• Provides tools for configuring YEI 3-Space Sensor devices
• Supports real-time data streaming and threaded orientation data recording
• Records orientation data as keyframes, thus making editing and clean-up easy
• Supports a widely used motion data file, the Biovision Hierarchy format (BVH)
• Open source and free, allowing users to use and modify the application without consequences

allow the user to edit the animation's skeleton and assign 3-Space Sensor devices to its bones.
6
User's Manual
3.1.3 Session Panel
The Session Panel allows users to play or edit animation sessions selected from the Current Session Drop-down Box.
The Session Panel is divided into to tabs, Pose Tab and Live Tab.
3.1.3.1 Pose Tab
The Pose Tab has many elements where the user can edit the bones of the skeleton, assign 3-Space Sensor devices to
bones, and calibrate the 3-Space Sensor devices. These elements and their usage are as followed:
•
Output Node: This drop-down box is for pairing a bone to a Virtual Sensor Node in the Node Graph Window.
Multiple bones may be paired with the same Virtual Sensor Node.
•
Sensor Pose Orientation: The check box and value boxes that are associated with this are dependent on
whether or not the Virtual Sensor Node selected has a 3-Space Sensor communicating with it. When the check
box is checked, the value boxes become enabled and a sensor model is shown on top of the bone. The value
boxes represent Euler angles in the order XYZ and manipulate the sensor model's orientation. The reasoning
behind this is for the calibration process to work properly.
•
Name: This text box is used for editing the bone's name. No two bones may have the same name, and the text
box assures this.
•
Parent Bone: This drop-down box is used for setting a bone's parent. It lists all the bones' names, except the
one selecting a parent, in alphabetic order.
•
Bone Length: This value box is used for setting the length of the bone.
•
Bone Pose Orientation: The drop-down box that is associated with this allows the user to select what method
to orient the bone, and the value boxes are used for setting the orientation of the bone.
•
Bone Offset: The value boxes that are associated with this allows the user to offset the bone from its parent. If
the bone's parent is “None”, then the offset is from the origin.
•
Calibrate Sensors: This button is used for calibrating sensors paired with bones for better motion capture. It
uses the data from the Sensor Pose Orientation and data from the sensor to do this.
3.1.3.2 Live Tab
The Live Tab has elements for streaming sensor data, and recording and playing animation sessions. These elements and
their usage are as followed:

User's Manual
4. Connecting Sensors
Depending on what type of 3-Space Sensor device(s) is being used, there are different ways for the Mocap Studio
application to detect the device(s). The Mocap Studio also can detect 3-Space Sensor devices in two ways. First way, is
if the devices are already connected to the computer before starting the application. Second way, is using the Sensor
Configuration Window.
4.1 Connecting a 3-Space Sensor Over USB
All 3-Space Sensor devices can connect over USB. This means of connection offers the fastest response time between
the connected sensors and the computer. The downside to connecting sensors this way is that any connected sensor
requires a cord running from the sensor to the computer. Because of this, movements and actor performances will be
limited to the length of said cords.
4.1.1 Connecting Sensors Before Starting the Mocap Studio
First, connect the device to a Mini-USB cord, by plugging in the included Mini-USB cord to the Mini-USB port on the
bottom of the 3-Space Sensor.
Inserting a Mini-USB cord into a 3-Space Sensor USB device.
Once plugged in, take the other end of the included Mini-USB cord and plug it into one of the free USB ports on the
computer. Once plugged in, the LED light should turn on for the device. Repeat this for any other desired 3-Space
Sensor devices.
After connecting the 3-Space Sensor device(s), the start-up of the Mocap Studio application will search for the device(s)
and connect to them. If some 3-Space Sensor device(s) were forgotten, read the following section.
4.1.2 Connecting Sensors After Starting the Mocap Studio
To connect sensors after starting the Mocap Studio, the Sensor Configuration Window needs to be open. To open the
Sensor Configuration Window, the Node Graph Window needs to be open. So in the Menu-bar of the Mocap Window,
click on “Node Graph” and select “Configure Node Graph” to open the Node Graph Window.

4.2 Connecting a 3-Space Sensor Over Bluetooth
Only the 3-Space Sensor Bluetooth devices may connect to the computer over Bluetooth. This method of connection
offers flexibility since there is no wire running from the sensor to the computer. The trade-off is that data will transmit
more slowly from the sensor to the computer. As a result, animations may appear choppier than animations captured
using a sensor connected over USB. The Bluetooth connection method also suffers from the limitation that Bluetooth
radios (or adapters) often have a very small number of devices that may be connected at once. This means that if a user
15
User's Manual
intends to capture an animation that requires many 3-Space Sensor devices, they might not be able to connect all their
sensors to the computer.
4.2.1 Connecting Sensors Before Starting the Mocap Studio
First, plug a Bluetooth radio (or adapter) into an available USB port on the computer and ensure that all needed drivers
for the Bluetooth radio are installed. If the radio is an internally installed one, the installation of the radio is already
done. Once installed, the next step is to power on the sensor. This is done by flipping the power switch on the side of the
sensor. With the sensor in front of the user, the sensor's buttons facing up, and the LED pointing to the left of the user;
the side of the sensor facing towards the user will have the power switch on it. The switch will be depressed into the
case of the sensor. So using a pen or some other pointed object, flip the switch towards the LED end of the sensor to
turn it on.

Once powered on, the LED on the sensor should light up. Next, the sensor must be paired with the computer's Bluetooth
radio. See the YEI 3-Space Sensor Bluetooth Quick Start Guide for further instructions on pairing Bluetooth sensors,
located here: http://tech.yostengineering.com/3-space-sensor/product-family/bluetooth#downloads_and_documentation.
Repeat this process for any other Bluetooth sensors.
After connecting the 3-Space Sensor device(s), the Mocap Studio application will search for the device(s) and connect
to them. If some 3-Space Sensor Bluetooth device(s) were forgotten, read the following section.
4.2.2 Connecting Sensors After Starting the Mocap Studio

4.3 Connecting a 3-Space Sensor Over Wireless Via a 3-Space Sensor
Dongle
Connecting 3-Space Sensor devices over wireless via a 3-Space Sensor Dongle is available to those who have purchased
3-Space Sensor Wireless 2.4GHz DSSS devices and at least one dongle. When connecting this way, the dongle is
connected to the computer via USB and the wireless sensor(s) communicate with the computer through the dongle. This
is often the best choice for users who intend to capture animations with a moderate number of 3-Space Sensor devices.
This is because there are no limitations to the actor's range of motion since all attached 3-Space Sensor devices are
wireless, and up to 15 wireless sensors may be connected to one dongle, thus allowing for many more 3-Space Sensor
devices to connect to the computer than the 3-Space Sensor Bluetooth devices. In practice, the wireless sensors will
18

communicate with the computer at higher rates than the Bluetooth, thus producing smoother animations.
4.3.1 Connecting Sensors Before Starting the Mocap Studio
First, plug in the 3-Space Sensor Dongle to the computer. To do this, locate the Mini-USB port on the bottom of the
dongle. The port is located on the small side of the dongle facing farthest from the LED light. With the port located,
plug the included Mini-USB cord into the port.
