Computer programming using tangible user interface where physical icons (phicons) indicate: beginning and end of statements and program constructs; statements generated with re-programmable phicons and stored

摘要

Tangible computing is the manipulation of real, physical objects to instruct and control computers. Computer programs can be created by manipulating physical objects that represent program language elements of a program or programming language. A tangible computing system calls for observation by a computer of a real, three-dimensional work space, where each physical object can be assigned a program language element. Assignment of attributes to, and/or movement of each real physical object results in the creation of a new program component. In this manner, a user can manipulate real, physical objects to create programs. Thus, the real world itself becomes a human-computer interface that allows a user to create programs and control digital processes.
