Toward more compatible human-computer interfaces
Article Abstract:
The need to improve human-computer interfaces becomes more critical as more people use microcomputers. Human factors is an important factor in designing a successful interface. The design should be an interactive design, which leaves some design options open so features and functions can be added after the designer sees how the user reacts. There are two kinds of activities that aid this process: task analysis where the designer has a detailed understanding of the tasks to be performed and how the user performs them and rapid prototyping where software tools simulate some of all features of an actual interface. Evaluation of a product design is done as the product evolves with results fed back into the design. The interface design should make it difficult to do something disastrous inadvertently; give the user the feeling of manipulating directly the entities of interest instead of the system doing it; have modules of applications for users tasks; use simple metaphors; permit interactive access only when needed; and help the user navigate through the information provided.

Toward better computer science
Article Abstract:
The economic well-being of the US depends on sound computer software. Inefficient, ineffective, or erroneous software can ruin a business and can even threaten the entire economy. Suppliers must produce correct, effective software. Computer science provides new insights and a scientific base for future software development, but computer science is a new field, with no senior leaders. Some institutions do not yet appreciate its importance. The demands of software production on computer scientists leave few teachers to educate the next generation. The government should establish a national policy of expectations, goals, and responsibilities. The policy should recognize current leaders and secure funding. To establish this policy, the government needs data showing how much of the GNP is software-dependent.
