Interesting interactive presentation tool: Mentimeter, including a limited free version. Go to https://www.mentimeter.com/ to check it out!
Within a minute, you can make a presentation with a multiple choice question. Click on present and your audience can react live by going to www.menti.com and type in the code shown. Press the F key to go in full screen mode.
In the free version, you can have a title slide with the menti.com code for your audience. Next you can raise five questions of different types. As an example, Word Cloud is also very interesting. You raise a question in response to which people can enter a word. For instance, the question can be: “Our company excels in the area of …”. The more people enter the same word, the bigger the word gets depicted.
As an alternative, you can use a tool named Kahoot! It’s comparable to Mentimeter, but a little more positioned as an educational tool for schools. Not so much as a tool for use in a commercial context. Description: “Kahoot! is a classroom response system which creates an engaging learning space, through a game-based digital pedagogy”. The tool is also free by the way.
