input patterns could be also be referred to as gestures as shown in fig3 a a simple input pattern can include a left right motion on a mouse 300 the computer terminal can be programmed such that if a left right pattern is entered on the input device according to certain parameters a location indicator is displayed the parameters can include for example a time parameter wherein the pattern must be entered in under a certain time such as 500 milliseconds the parameters can include a distance parameter wherein the left right pattern is measured for example the parameter can specify that the left right pattern must cover 250 pixels left to right on the screen and have an up down variance of no more than 20 pixels in other embodiments of the invention the distance parameters can be set by a user of the computer terminal in accordance with their personal preferences the parameters can include an acceleration parameter the acceleration parameter can specify each movement of the pattern is performed at a certain rate of acceleration for example the acceleration parameter can specify that the each of the left and right movements of the pattern must reach an acceleration of 20 centimeters per second as a second example the acceleration parameter can specify that the each of the left and right movements of the pattern must reach a deceleration of 20 centimeters per second in preferred embodiments of the invention the parameters can be set to minimize false positives where the location indicator is displayed in response to normal usage when a user did.
