How can we read faces when everyone’s wearing a mask
Q is for Questions
Inspiration for this viz came during the ‘searching for an idea stage’ in my 2020 #Ironviz feeder entry.
Unfortunately I just didn’t have time to work up the idea of visualising emotions to get an entry in for the health and wellness topic.
So for this weeks theme I thought I would implement a (very paired down) component of the viz I had envisioned.
Reading nonverbal cues has become more important than ever given everyone is wearing a mask to protect themselves and each other through COVID-19.
Key Techniques for this viz
- For the lego styled plots I have used George Gorczynski’s Pointillism in Tableau technique, which uses processing to extract the X Y coordinates from .png files. George’s blog post is here – Photo Art in TableQuick note – make sure you resize your image files down to c50 pixels width in a tool like paint.net before loading into the ‘processing’ tool to extract the X Y and colour coordinates otherwise the pointillism effect is lost!
- The lego effect takes advantage of Ken Flerlage’s Lego button image. Kindly provided for use in his blog – Lego art in Tableau – to achieve the colour and lego button effect this uses a dual axis – one to plot the square and the other to plot the shape – remember to remove colour off the shape so it shows through correctly.
- Automatic deselect marks in Tableau – by Luke Stanke – I used this because I didn’t wish for the the face to grey out when you clicked on the individual lego tiles.
