<p>A device for indicating a present status for a certain parameter, such as the charge of a battery. A parameter-sensing unit devised to sense a parameter value is connected to a control unit, devised to present an indicator area on a display. The indicator area is defined within an indicator frame, and an area portion of the indicator area is marked to represent a relative parameter level. A gyro sensor is connected to the control unit, wherein the control unit is devised to present the marked area portion as a bottom portion of the indicator area with a gyro-controlled upper border of the area portion which is maintained substantially horizontal. This way, the marked area portion will be experienced as a fluid, confined within a jar represented by the indicator frame.</p> |
