Abstract

We have designed and implemented a visual programming environment, Hyper-flow on the PenPoint operating system. We call it HF/PP for short. Its primary goal is to provide a framework for UDUI in educational applications. The design of HF/PP, which uses only a pen and a microphone for input, is part of a research project to develop a pen based computer system for teaching preschool through twelfth grade mathematics. The article discusses the UDUI capabilities of HF/PP, represented by the programming constructs; form and formula, or the form/formula paradigm. To explain the paradigm, and other HF/PP constructs, we present three examples: converting between Fahrenheit and Celsius, designing arithmetic worksheets, and querying student records
