Visualizing screen overlaps 2
The problem
● ”It's quite easy to overlap others' writing”;● ”it's hard to know if you overlap existing
drawings”;● ”Might be hard to avoid overlapping in some
cases”;● ”It is a bit uncomfortable because it overlaps”;● ”Sometimes it is hard to manage because we
should be careful to prevent our words from overlapping”.

How to measure?
● Questionnaire:● How much effort did it take to avoid overlapping?● Did the participants contents overlapped?
● These are subjective!● Can we use the system-interaction data?

Idea
● When writing/drawing each user ”claims” some territory on the screen.

Technical details
● Library used for generating the heatmap: http://jjguy.com/heatmap/;
● Dot size (territory): 150 pixels;● The library was modified to fit our
scenario (multiple entities – the users);● A heatmap was generated for each user;
the resulted images were processed to obtain the final result.
