A tool which helps in demonstrations, presentations or if you just need to explain someone something on your computer.
DemoHelper is an annotation and screen zoom tool you can use for technical presentations that include application demonstrations.
DemoHelper runs unobtrusively in the system tray and is activated by either customizable hotkeys or the context menu of the tray icon.
You can draw on the screen to mark special areas, or you can zoom in on an area on the screen.
Use cases include meetings where you have to explain something on the screen or teachers presenting lectures to students in computer classes.
Windows 2000 not supported
DemoHelper requires Windows XP or later. It won't work on Windows 2000!
DemoHelper runs in the system tray, where you can activate and configure it with a simple right-click:
In the options dialog, you can configure the hotkeys for the two main modes of operation: zooming and drawing.
To start the drawing mode, either press the hotkey you configured for it, or double-click on the icon in the system tray. Once in drawing mode, you can draw on the screen:
As shown in the screenshot above, it's possible to draw arrows and lines in different colors. Also a special "Marker" is available to highlight areas on the screen, as done above with the "file2.*" filenames.
The colors are merged together with the screen by default. But it's possible to draw with solid colors if needed.
