How to Use

• vJoy Driver

  1. Make sure no physical controller is attached
  2. Download vJoySetup.exe from vJoy sourceforge and install (Recommended to check all 4 programs)
  3. Make sure no other program is capturing controller (e.g. Steam)

• Android App

  1. After installing apk on Android phone, tap upper left corner to see all options
  2. Connection modes:
     1. Bluetooth requires the phone to enable bluetooth and has already paired with target PC at least once
     2. Wifi requires the phone to connect to the Mobile Hotspot of Windows PC (Or at least in the same local network)
        When connecting, need to enter the same IP address displayed on PC app
        If connection failed, check if Windows PC firewall is blocking the app
  3. Control options:
     1. Default: phone motion controls both acceleration and steering
        Two changing numbers [left indicates horizontal angle (Roll), right indicates vertical angle (Pitch)]
        See Android README for more information
     2. Alternative: phone motion only control steering
        Acceleration is controlled by pressing LT / RT
        Used if default mode is too hard to control
     3. GamePad: no steering is enabled, but has more buttons
        Used to control the rest of a game (such as menu, car view, etc.)

• Windows App

  1. Install Windows application
  2. Minimizing the app will hide app to system tray (with a notification)
  3. Left textbox contains all essential program notifications

For Games

By default, vJoy will use settings of xbox controller, for most modern games. Make sure to tweak in-game steering settings, because most games have been using stabilization algorithms to smooth out the steering axis input. Some may result in a lagging of steering, others may make steering extremely slow or fast.

Potential Improvements

• Try other sigmoid-shape functions to improve motion control
  Right now using linear function for both steering & acceleration
• Learn more about real-time data transmission technologies
  The TCP socket is holding up data instead of sending it immediately, which results in a slightly lagging behavior
• Find alternatives to vJoy driver which supports more efficient real-time control feeding
