Voice Control

Bigscreen supports OpenVoiceOS, a free and open-source voice assistant that can be run completely decentralized on your own server.

Download new apps (aka skills) for your Bigscreen or add your own ones for others to enjoy.

Remote control your TV via CEC

CEC (Consumer Electronics Control) is a standard to control devices over HDMI. Use your normal TV remote control, or a RC with built-in microphone for voice control and optional mouse simulation.

Application Launcher

Bigscreen replaces your DE, to stop an application from showing up you can edit /etc/xdg/applications-blacklistrc

Adding new applications only requires a .desktop file

see plasma-bigscreen/bigscreen-image-settings for more settings you might want to tweak in a Bigscreen image
