Abstract

This disclosure covers a program called the Integrated Laboratory Controller (ILC). The ILC program is comprised of two separate programs: a logger program called LOG and a participant screen capture program called CAPTURE. The ILC program ties together a logger program, the participant's PC, and the VCR (Figure) in order to provide an integrated system for conducting and analyzing usability evaluations. The goal for writing this program was to provide a single interface for the control and data recording requirements of a test administrator so that one person could run, log, and analyze a usability evaluation. Another objective of this program was to provide an easier-to-use interface than what is available with current logger programs. This was accomplished by using an intelligent parser for identifying logger commands.

Centralized Method for Logging, Controlling, and Analyzing Usability
Evaluations

      This disclosure covers a program called the Integrated
Laboratory Controller (ILC).  The ILC program is comprised of two
separate programs: a logger program called LOG and a participant
screen capture program called CAPTURE.  The ILC program ties together
a logger program, the participant's PC, and the VCR (Figure) in order
to provide an integrated system for conducting and analyzing
usability evaluations.  The goal for writing this program was to
provide a single interface for the control and data recording
requirements of a test administrator so that one person could run,
log, and analyze a usability evaluation.  Another objective of this
program was to provide an easier-to-use interface than what is
available with current logger programs.  This was accomplished by
using an intelligent parser for identifying logger commands.  With
each word entered, the program prompts the person logging as to the
next allowable keyword.

      A benefit of using this program is its ability to capture
screen information from the application under study.  The person
logging could record screen identifications, titles, and messages
without having to manually enter them.  They could be saved in a
separate file and/or sent over to the logger program as they
occurred.  If desired, the person logging could issue a command
(grab) to capture the full screen of an application and save it in a
file.  The screen capturing ability frees the person logging from
having to manually record the screen navigational information into
the log.

      Another benefit is the ability to initiate on-line
questionnaires on the participant's PC from the logger's PC and have
the results sent back to the logger's PC for analysis.  This saves a
person from having to key-in the paper questionnaire results into a
file for subsequent analysis on the host.  The most frequently
performed statistical analysis such as determining means, medians,
confidence limits, and one-way analysis of variance can be conducted
by the logger program.

      The ILC program solves the problems of multiple input/output
interfaces by providing a single point of data and control.  Using
the ILC program, the person logging can control an issue command to
the participant's PC from the logger program.  On-line surveys c...
