Patent ID: 7752567

Claim:
A method for providing an easily recognizable visual feedback to a user in a multi-parameter aircraft instrument display of manually induced variations in individually selected manually adjustable dimensional data associated with a selected one of a plurality of displayable parameters in said multi-parameter aircraft instrument display, said multi-parameter aircraft instrument display containing a plurality of said displayable parameters in a simultaneous visual display thereof, each of said parameter displays varying in accordance with a selected one of a plurality of manual adjustments of said dimensional data associated therewith for providing variations in said dimensional data, each of said individually selectable parameters having a unique associated visible indicia which uniquely visually identifies a particular one of said individually selectable manually variable parameters as being associated with a particular one of said plurality of displayable parameters; said method comprising the step of providing visual confirmation that the correct parameter in said multi-parameter display which the user intends to vary is having its associated dimensional data manually varied, said visual confirmation being provided by visually enlarging the display of said selected one of said simultaneously displayed parameters with respect to said non-selected simultaneously displayed parameters from an original normal display size in said display for a predetermined time period in response to said manual adjustments of said dimensional data associated therewith; whereby the user may easily recognize whether the correct parameter is being manually varied, said method further comprising the steps of visually reducing the display of said selected one of said simultaneously displayed parameters back to its original normal display size after said predetermined time period in response to a cessation in said manual adjustments of said dimensional data associated therewith, said predetermined time period being dependent on a continuation of said manual adjustments of said dimensional data associated with said displayed parameter being varied, initializing a predetermined timing sequence in response to said visually enlarging of said display of said selected one of said simultaneously displayed parameters and continuing to iteratively determine if said manual adjustments of said selected one of said parameters are continuing during said predetermined timing sequence in order to reinitialize said predetermined timing sequence each time said iterative determination indicates said manual adjustments to be continuing until said manual adjustments cease, said predetermined time period of said enlargement being determined by said cessation in said manual adjustments and comprising said initialized predetermined timing sequences which comprise said iterative determination.
