What's hıve mınd?
hıve mınd is an interactive feedback tool for lectures. The lecturer or host can present slides on a projector with an additional short URL and every student or spectator can simply enter this URL into their smartphone or notebook. After entering the URL, they will see the slide from the projector on their device and may mark an arbitrary point on the slide.
The host may then show a heatmap of all positions picked by his audience and hence show the feedback of an entire lecture hall in a single picture.
