| Abstract | Computer Aided Design (CAD) software can be difficult to learn. A major contributor to this entry barrier is CAD interfaces’ usage of symbols associated with CAD operations. This paper studies which symbols minimize recall time and optimize retention via two studies. We performed an initial exploratory study to identify which 2D symbols intuitively describe common CAD operations. Then we conducted a second study with three separate groups using different input methods to test which input method improves retention and recall time. Each group used one of three input methods: choosing preexisting Autodesk CAD operation symbols, choosing our 2D symbols derived from the symbol study, and physically drawing those same symbols. We measured participants’ accuracy and time spent on each question. The results indicated that there is a decrease in the time taken to submit responses, which correlates to recall time. The group physically drawing the symbols improved the most compared to the group selecting the symbol study symbols and the group selecting Autodesk operation icons. For retention, as measured by correctness, our statistical analysis indicates that there does not appear to be a significant difference between the three groups. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
