Abstract
A user interface includes a touch screen configured to receive stroke input(s). The user interface is arranged to display a graphical trace of the received stroke input on the touch screen and to determine whether a criterion is fulfilled and if so remove at least a portion of the graphical trace, wherein the criterion is based on the received stroke input.
Claims26
A user interface comprising a touch screen adapted to receive stroke input, wherein said user interface is configured to display a graphical trace of said received stroke input on said touch screen and to determine whether a criterion is fulfilled and if so remove at least a portion of said graphical trace, wherein said criterion is based on said received stroke input.
A user interface comprising a stroke input receiving touchpad, a stroke input related trace displaying screen and a stroke based criterion checking controller for causing said screen to display said trace while said criterion is not fulfilled and for causing said display to first display at least a portion of said trace and thereafter not displaying said trace when said criterion is fulfilled.
A user interface comprising a touchpad for receiving stroke based input, a display and a controller, wherein said touchpad is operatively connected to said controller, wherein said controller comprises at least one stroke input based criterion checker having a first and a second state and said controller is operatively connected to said display, wherein said display is configured to display a trace relating to said received stroke input when said criterion checker is in said first state and to firstly remove a portion of said trace and secondly remove said trace completely when said criterion checker is in said second state.
An apparatus comprising touch screen means for receiving stroke input and for displaying a graphical trace of said received stroke input, means for basing a criterion on said received stroke input, and processing means for determining whether said criterion is fulfilled and if so, to remove at least a portion of said graphical trace.
A method for displaying graphical traces of received stroke input on a touch screen, said method comprising:
- receiving a stroke input;
- basing a criterion on said received stroke input;
- displaying a graphical trace of said stroke input;
- determining whether said criterion is fulfilled;
- and if so
- removing at least a portion of said graphical trace.
A computer readable medium stored in a memory comprising at least computer program code for controlling a user interface comprising a touch screen, said computer readable medium comprising:
- software code for receiving stroke input,
- software code for displaying a graphical trace of said stroke input,
- software code for basing a criterion on said received stroke input, and
- software code for determining whether said criterion is fulfilled and if so removing at least a portion of said displayed graphical trace.
