WebTester
This project targeted managers of web sites. It analyzed log files of the site visitors, stored on the servers. The analysis was by statistics of recurring activity, based on a model of site navigation.
The method for the
statistical analysis was disclosed in a book about eCommerce research.
The methods of WebTester are used today for
agile testing of the effectiveness of web sites, installed on Cloud and Edge mini-servers.

ModeTester
This project was a program targeting specific problems of user-machine coordination. Contrary to the first three projects, which targeted the testing stage, this program was used at the design stage, to
identify error-prone controls. The program features included:
-
A tool for the designers to define the system operation, based on schemes representing the operational panels (user interfaces)
-
A means for the designers to define the operational rules, by reference to the operational panels
-
A program used to detect violations on good design practices
-
A reporter, used to generate report to the designers about design mistakes.
This method is used today in guidelines for
assuring operator-machine cooperation.

AlarmController
This project is actually a set of applications of a methodology for alarm design. Common alarm controllers, which enable tradeoff of missed vs. false alarms, by controlling the alarm threshold. The method
used by AlarmController is based on alarm protocols, which reduces the rate of nuisance while in alarm condition.
The alarm controller was developed by building prototypes for three applications:
-
A camera used for intruder detection
-
Medical monitors
-
Public alarms about environmental threats.
Today this method is used in guidelines for
alarm design.
