If you want to draw in your presentation and have a computer or laptop without pen input, then a graphics tablet from the HUION brand is recommended as a more cost-effective variant. For example the HUION KAMVAS 20 model. You can connect the graphics tablet to your computer via USB. Alternatively, there are convertible laptops of various brands with integrated pen input.

For the microphone, the Yeti Pro from Blue Microphones is recommended.

Presentation slides must first be converted into a PDF file. In order to divide animations on individual slides, two alternatives are mentioned with which this can be carried out.

PowerPoint: PPspliT is a tool that splits animations into multiple slides. [Instructions]

If you have problems with slide numbers of splitted animations, please follow these instructions.

LibreOffice: ExpandAnimations is a LibreOffice/OpenOffice.org extension to expand animations before exporting to PDF. [Instructions]

There is no native support for iPads as lectureStudio was developed with Java and there is no official Java Runtime Environment (JRE) for iPad. Native support for iPad is already being planned.
Solution:
With Duet Display you can use your iPad as an external digitizer for lecturePresenter on your PC or Mac. This assumes that you have a Windows or macOS capable computer.

If you are getting an error by starting a web service like a quiz or enable messages, it is likely that there is a local firewall set up with per-application rules. You may also start getting the error after upgrading lectureStudio. Some firewalls check executable file fingerprint. As the executable file changes with upgrade, the firewall starts blocking the executable, although you may have added exception rule for lecturePresenter already.

For built-in Windows firewall, go to Control Panel > System and Security > Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall. There you have two options: 1. Add an exception for lecturePresenter.exe manually or 2. Delete existing exceptions for lecturePresenter.exe and restart lecturePresenter. Windows will ask you to allow network access and if you accept, it will create the firewall rules for you.

lectureStudio is currently being developed internally at the TU Darmstadt by the Department of Electrical Engineering and Information Technology and the Department of Computer Science, Embedded Systems and Applications Group. The project is released on GitHub under the GPLv3 license. There you can discuss feature requests or implement features yourself. All extensions must be taken into account under the given license.
