The obstacle so far has been communication in delivering material from lecturers to deaf students. This is because: 1) 90% of deaf students in Visual Communication Design cannot read written sentences that are too long. Deaf students of Visual Communications Design are accustomed to using hand sign language, namely a visual language that emphasizes the ease of moving hands, not the order of sentences based on SPOK, 2) The digital application used by deaf students to translate the lecturer's voice does not function properly. This is because sentences/words often appear that do not match what the lecturer in the course said. The aim of designing pictogram icons as a learning medium for Visual Communication Design students is that deaf students can understand and understand information about lectures and can carry them out well, so that deaf students are formed who are able to compete in society. To achieve this goal, the Innovation Development method is carried out using the Lee & Owens Model method which produces pictogram icons which can help simplify verbal and written language into visual language.
