Frequent questions

Here we answer frequently asked questions about Semanux.

Semanux is an advanced and intuitive software for controlling computers and Internet browsers. It enables the use of alternative input devices such as gamepads and joysticks, as well as hands-free control via technologies such as head tracking, eye tracking and non-verbal speech input. The built-in AI module will analyze web page content and adapt the controls to the recognized content.

Semanux is the tool of choice for those who, due to their situation or personal circumstances, cannot operate computer systems with a mouse and keyboard, such as doctors in sterile operating rooms or people with paraplegia.

Semanux works on computers with Windows 10 (or higher) and soon also on macOS 13 (or higher) and with an internet connection. We further recommend a decent webcam (720p or higher) and an Intel i5 processor (or better).

Semanux supports a variety of different input devices to be suitable for different situations and personal needs. Besides the classic input devices keyboard, mouse and touchscreens, Semanux enables advanced control methods through additional input devices.

  • For head control you need a webcam. We recommend a resolution of at least 720p or 0.9 megapixels and a recording rate of 30Hz or more. Webcams of older laptops are often not suitable because their image quality is not sufficient.
  • Joysticks: Semanux supports the "Competition Pro Extra" from Speedlink. Other joysticks may also work, but have not been tested.
  • Gamepads: Semanux supports the Xbox gamepad as handheld and adaptive gaming kit. Gamepads from other manufacturers (PlayStation, Wii, Stadia) may also work, but have not been tested.
  • Pedal: Semanux supports the "f-pro USB footswitch" from / dr. dresing & pehl GmbH. Other switches and buttons may work, but have not been tested.

Please contact to have your product added to the list of supported devices or to discuss support requirements.

Windows can only forward the video stream of a webcam to a single program. Therefore, a webcam cannot be used as an input device for Semanux and as a video source for a video chat program at the same time. We recommend connecting a second webcam to use one webcam for Semanux and one for the video conferencing program. Alternatively, there are third-party programs to split the video stream of one webcam into two or more virtual webcams:

The programs and their functional reliability are subject to the conditions and guarantees of the respective manufacturers.

There can be different reasons why Semanux does not start automatically after starting the computer or logging in the user account.

  1. The checkbox "Enable run on login" in the general options must be set.
  2. The Windows user account must be an administrator account.
  3. An antivirus program prevents the execution. Set "Semanux" to the list of allowed programs in the settings of the antivirus program. For more information, please contact the manufacturer of your antivirus program. Semanux recommends Windows Defender as antivirus program.

Other programs, such as Valve Steam, may use the same APIs as Semanux, causing interference. This may interfere with the use of Semanux, and we recommend disabling such features of other programs.

We recommend disabling the Xbox Game Bar on Windows computers. To do so, go to Windows Settings, category "Play", search for "Game Bar" and disable the function.
