Apparatus and method for touch screen interaction based on tactile feedback and pressure measurement
First Claim
1. An apparatus including a display section with a touch screen, the touch screen being adapted to display at least one graphical user interface object and detect a touch position on the touch screen, the touch position being inputted with a user'"'"'s finger or a pointing device, the apparatus comprising:
- a haptic feedback generating unit attached to the touch screen and adapted to generating haptic feedback;
a pressure sensing unit attached to the touch screen and adapted to detect pressure applied to the touch screen; and
a controller section adapted to control and drive the display section;
whereinthe graphical user interface object displayed at a display location on the touch screen has a plurality of logical states, the display location defined by a boundary of the graphical user interface object,the controller section determines a current logical state of the graphical user interface object using a history of detected touch positions and a history of detected pressure values, the current logical state of the graphical user interface object includes at least one of a selected state and an actuated state,the controller section further determines a form of the haptic feedback to be generated depending on (i) the detected touch position, (ii) the detected pressure value and (iii) the determined current logical state of the graphical user interface object, andthe haptic feedback generating unit further applies, to the touch screen corresponding to the display location of the graphical user interface object upon determination by the controller that at least the detected touch position is within the boundary of the graphical user interface object, a first predetermined force pattern to the touch screen upon determination that the current logical state of the graphical user interface object is the selected sate, and a second predetermined force pattern different from the first predetermined force pattern upon determination that current logical state of the graphical user interface object is the actuated state.

Abstract
An apparatus includes a display section with a touch screen, and the touch screen is adapted to display at least one graphical user interface object and detect a touch position on the touch screen. The apparatus has a haptic feedback generating unit attached to the touch screen and is adapted to generating haptic feedback. A pressure sensing unit is attached to the touch screen and adapted to detect pressure applied to the touch screen. A controller section is adapted to control and drive the display section. The graphical user interface object displayed on the touch screen has a plurality of logical states. The controller section determines a current logical state of the graphical user interface object and a form of the haptic feedback to be generated depending on the detected touch position.

15. A graphical user interface method for a touch screen, comprising:
-
displaying a graphical user interface object at a display location on the touch screen, the graphical user interface object having a plurality of logical states, the display location defined by a boundary of the graphical user interface object; detecting a touch position on the touch screen, at which a user'"'"'s finger or a pointing device is touching; detecting pressure applied on the touch screen when the touch position is detected; and generating haptic feedback in response to the touching, a form of the haptic feedback being determined depending on (i) the detected touch position, (ii) the detected pressure value and (iii) a current logical state of the graphical user interface object; wherein the current logical state of the graphical user interface object is determined by using a history of detected touch positions and a history of detected pressure values, the current logical state of the graphical user interface object includes at least one of a selected state and an actuated state, and the generated haptic feedback response is applied to the touch screen corresponding to the display location of the graphical user interface object upon determination that at least the detected touch position is within the boundary of the graphical user interface object, a first predetermined force pattern to the touch screen upon determination that the current logical state of the graphical user interface object is the selected state, and a second predetermined force pattern different from the first predetermined force pattern upon determination that current logical state of the graphical user interface object is the actuated state. - View Dependent Claims (16, 17, 18)
