Abstract

Prior art provides a Graphical User Interface (GUI) control which graphically monitors the CPU load in the system. The X-axis represents time, and the Y-axis represents the percentage of CPU usage from 0% to 100%. As the CPU usage changes over time, the graph is updated accordingly. However, a blind user needs an alternate method for monitoring CPU usage.

CPU Monitor for the Blind User

      Prior art provides a Graphical User Interface (GUI) control
which graphically monitors the CPU load in the system.  The X-axis
represents time, and the Y-axis represents the percentage of CPU
usage from 0% to 100%.  As the CPU usage changes over time, the graph
is updated accordingly.  However, a blind user needs an alternate
method for monitoring CPU usage.

      This system provides the blind user with the ability to monitor
CPU utilization.  The CPU load is manifested to the user audibly, by
means of an audible alarm which fluctuates over time as the CPU load
changes.  A low pitch indicates a low rate of CPU usage, and a high
pitch indicates a high rate.  The accuracy inferred by the audible
monitor to the user is increased over time as the user gains
experience in listening to the audible alarm.

Substituted elements of this system include:

o   The audible alarm can be accompanied by an annotated voice
    message (e.g., "time to get coffee") to indicate certain
    preconfigured CPU levels, e.g., 50%.

o   The audible alarm can be based on pitch or frequency.

o   The audible alarm can be one continuous sound, or it can be a
    series of short beeps at varying pitches and/or frequencies.

o   The audible alarm can be accompanied by a visual monitor.

o   Volume control.
