Megadodo Games DMD-001A DecaMove and Dongle

Product details

Setup

Download and install deca hub Requirements:

• Steam VR
• Windows 10

Connect dongle to PC

Download and Install the DecaHub installer from this link: https://www.deca.net/decamove/setup Open the DecaHub software from your Windows Start menu

DecaHub software will show the connection status change from “Closed” to “Open”. It is recommended to connect the dongle to a front USB port if available.

Pairing
Turn on the DecaMove by pressing the button for 2 seconds. DecaMove LED will change from orange (not connected) to blue when it successfully connects to the dongle.

Notice the connection status changes to “Streaming” and the compass icon rotates according to how you rotate your DecaMove. Pairing should happen automatically once the dongle is connected and theDecaMove is switched on. Please refer to the troubleshooting section for any issues.

Calibration
(For first-time use only) DecaMove delivers precise, low latency, and high accuracy hip tracking. The device’s sensor fusion relies heavily on the magnetometer which MUST be calibrated before first use. Calibration is easy and should take less than 20 seconds, please follow the instructions in this link: https://www.deca.net/decamove/support/decamove– magnetometer – calibration-procedure/

Fit
The DecaMove can be placed anywhere along the waist and hip area but we recommend placing it on the sides so that it doesn’t interfere with crouching down or bending forward.

Launch games from decahub Launch Tab
In order to support many games without the need for the game developer to install the devices’ SDK, it’s important that you launch games from the DecaHub. Go to the Home tab and click the game you want to play (e.g. Pavlov VR) A checkmark next to it means that DecaMove supports this game.

In-game calibration
Calibration is needed at the start of every gameplay session and at any time you feel the device heading has drifted. DecaMove’s gestured calibration does not require any special settings or any pressing of buttons: Simply hold your controllers close together in front of your hips. Make sure your hands point in the same direction as your head. Then look forward and don’t move for 1 second. You will see the “Calibrating … ” message show up, hold the position until it’s complete. That’s it. You are calibrated.

Game settings
Once the game is running, go to the game settings menu and make sure that the locomotion method is set on continuous and head-oriented and set the dominant hand to right-handed. Also, depending on the game, remove any joystick manipulation mechanism (e.g. locking the joystick in Contractors, or smoothing the joystick in Bone works). This is a very important step. Without removing it, the movement will be wrong. Try pushing the left joystick forward to walk around, you will see that your movement is now relative to your hip. Enjoy the game with DecaMove!

DecaMove In-Game UI
The DecaMove does one thing and it does it efficiently and accurately. It allows you to navigate with your hip with minimal drift so that your movement direction can be independent from your headset or hand controllers. It may take a bit of time to get used to this type of navigation control, especially if you are used to playing with controller-based movement, but it will give you an advantage against other non-DecaMovers. We add an In-Game UI that shows your hip headings and the DecaMove battery gauge. You can turn it On or Off by clicking on the DecaMove button. Visit the Tips section for more info of how to use the DecaMove properly.

Advanced user?
If you find out that something is wrong, you can always check the log. You should find the logs folder inside the installed folder (C:/Program Files/Megadodo Games/DecaHub) If you could zip that folder and send it to us, it would help a lot!. You can also try and debug it yourself, open the log file and try to find an error message such as ERR or FTL.
