What I gathered from the readings was a greater outlook on how big of a role clarity and context plays on the success of a pictogram. Also a look into the early history of representative image making was nice to keep in the back of my mind whilst learning about modern pictograms. Unfortunately the video seemed to be corrupted and started over once it got half way through.
The clarity of the pictogram depends on several factors. The pictogram must be in formal alignment with other pictograms of a set. They should be un ambiguous in form and should not be weighed upon by the stylistic choices of the designer (something I have had a hard time with). Also the pictogram is highly influenced by its surroundings and the norms of the culture in which it is represented. I'm wondering if we will be exploring placement in some way.
