Many domestic appliances and much office equipment is controlled using a keypad and a small digital display. Programming such devices is problematical for the blind and visually handicapped. In this paper, we describe a device that may be used to read the displays on these devices. The device is designed to accept a description of the display being read, which specifies the types and locations of elements of the display. Images are captured using a handheld webcam. Images are processed to remove the distortions due to the camera orientation. The elements of the screen are interpreted and a suitable audio output is generated. In suitably illuminated scenes, the display data is interpreted correctly in approximately 90% of the cases investigated.

Primary Subject area Medical Education Background The COVID-19 pandemic and physical distancing measures limited in-person learning experiences for resident postgraduate learners through mandated social distancing measures. Our training program responded by creating online synchronous and asynchronous learning opportunities to supplement learning and replace lost experiences. Virtual MacPeds is an online curriculum created using Kern’s six-step approach to curriculum development to supplement resident learning during COVID-19. The curriculum included online lectures, a live teaching calendar that includes links to sessions across rotations and subspecialties, and a resource rolodex with links to online learning materials. Objectives The purpose of this study is to evaluate the components of the Virtual MacPeds curriculum that were most useful to residents. Design/Methods Virtual MacPeds was piloted from March 2020 to June 2020 to 51 core pediatric residents in PGY1-4. The Kirkpatrick Model for learning evaluation was used to assess resident reaction to the implementation of the curriculum. A voluntary online survey was emailed to residents with the opportunity to respond from June to July 2020. Descriptive statistics were used to assess learner engagement and perception of the curriculum. Results Resident response rate was 38.2% (n=20, PGY1 =8, PGY2 =6, PGY3=5, PGY4=1). 95% of respondents had reduced in-person teaching sessions during COVID-19 and 80% had impacted clinical rotations (self-isolation, virtual care, patient volumes). Prior to Virtual MacPeds, 65% used online educational resources. 95% used the curriculum, all of whom found it helpful in fulfilling Royal College learning objectives. 85% of participants attended the online lectures - those who did not attend noted schedule conflict. 100% would use Virtual MacPeds in the future. Participants noted that Virtual MacPeds should include a live teaching schedule (100%), online lectures (84.2%), self-study modules (73.7%), resource rolodex (52.6%) with suggestions for recorded lectures (89.5%) and simulations (57.9%). Conclusion Virtual MacPeds is an acceptable and useful supplement to resident learning during COVID-19. Useful elements of the curriculum include online lectures, a live teaching schedule, resource rolodex and self-study modules.
