Visual Turing Machine is a software tool whose name pretty much sums up its purpose - it allows you to create designs for Turing machines. This type of app can be used by students who study Computer Science or Mathematics, for instance.

In order for this app to work, you need to have Java installed on your computer. Simple details regarding how to launch the program can be found in the Readme file.

Since this is a portable piece of software, installing Visual Turing Machine is not necessary. It means that you can store the tool on a USB flash drive or any other removable device, save it to any computer and directly run its executable file.

What's more important is that the Windows Registry is not updated with new entries, and no leftover files can be found on the hard drive after program removal.

The interface of Visual Turing Machine is based on a standard window where you can access several design tools on the left side of the frame. You can use the "drag and drop" method to draw symbols and instructions (left, right, do nothing), as well as import Turing machine files from the hard drive (TM format). But you can also make connections between objects and write text.

When selecting an object in the drawing area, you can open the context menu and set it as N or the first instruction, edit properties, as well as to cut, copy or delete it. You can define a new symbol, adjust the running speed and write symbols on the tape.

The easy-to-use program requires a high amount of CPU and system memory, supports keyboard shortcuts and includes user documentation. No error notifications have been shown during our evaluation and the utility did not hang or crash. The bottom line is that Visual Turing Machine offers a simple solution to draw Turing machines.
