The system is particularly advantageous because it provides a system for distributing page images such as worksheets, examinations or forms to multiple devices. The system allows independent paging and writing on the distributed materials; collection of the strokes added to the distributed pages images; and aggregating and displaying those strokes or summary information in a useful manner. For example, an instructor might receive the current work of the students for a particular examination question and view those strokes in a parallel manner or a combined manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stroke and image aggregation and analytics","description":"The present invention overcomes the deficiencies of the prior art with a system for stroke and image aggregation and analytics.
