• Adaptable virtual pointer. Displays a glowing dot on the screen that follows the movements of the physical device. Size, color, and intensity are configurable to suit different lighting conditions and screen types.
• Highlight effects. Includes features such as focus circles and zoom effects that let you emphasize specific areas during presentations. These effects keep the audience's attention on key content.
• Logitech Spotlight compatibility. Fully supports the features of the Logitech Spotlight device, including motion detection and button presses. The application automatically recognizes the hardware when it is connected.
• Advanced button mapping. Each button on the device can be programmed to perform specific actions. Options include simulating presentation keys, switching visual effects, or controlling operating system functions.
• Long-press events. Detects and distinguishes between short presses, long presses, and movements while a button is held down. Each type of interaction can be assigned its own independent action.
• Customizable key sequences. Lets you assign complex key combinations to physical buttons. This makes it easy to control presentation software without touching the keyboard.
• Visual preset cycling. Implements a system for switching between different pointer configurations on the fly. Presets are sorted alphabetically, so you can organize them using numeric prefixes.
• Scroll control. Offers functions for using the device's buttons as vertical or horizontal scroll controls. This is useful for navigating documents during presentations.
• X11 integration. Works exclusively on Linux systems running the X11 display server. The application intercepts device events at a low level to ensure tracking accuracy.
• Input virtualization system. Creates virtual uinput devices to handle events without conflicting with the system. This approach allows physical inputs to be redirected to custom actions.
• Included udev rules. Provides predefined configurations for device permissions on Linux systems. The rules grant the necessary access without requiring administrator privileges during normal use.
• Command-line mode. Includes advanced configuration options via terminal parameters. Lets you adjust behavior without a graphical interface, which is handy for automated use.

Development of Projecteur began in 2017, started by Jahn Fuchs as a solution to the lack of native support for the Logitech Spotlight on Linux. The project grew out of a personal need to use this device in professional environments without proprietary software. The application is written in C++ and uses the Qt framework for its graphical components. The code interacts directly with Linux input subsystems through APIs such as X11 and uinput. Development remains active, with updates that improve compatibility with different Linux distributions and input devices.
