Abstract
A dual user interface trackpad that utilize capacitive sensing to detect user proximity and/or touch and inductive sensing to detect stylus input, allowing a user to select specific content or a window on an associated display with touch, to reposition and manipulate the selected content or window with touch to facilitate more convenient entry of additional content amongst the selected content or window using the stylus, and to indicate completion of the entry of content with another touch and/or proximity event on or near the trackpad.
Claims18
A method for engaging a trackpad with user proximity and/or touch and with a stylus, said trackpad comprising capacitive sensing and inductive sensing circuitry, wherein the capacitive sensing circuitry is used to detect user proximity and/or touch events on said trackpad and the inductive sensing circuitry is used to detect stylus position and movement on said trackpad, wherein said method comprises the steps of detecting a user proximity and/or touch event on said trackpad for selection of a window displayed on an associated display, of monitoring the stylus position and movement for entry of content in said window, and the step or steps of detecting a user proximity and/or touch event to reposition and/or set the position of said window.
A trackpad comprising capacitive sensing circuitry as well as inductive sensing circuitry, said trackpad associated with a display, wherein the capacitive sensing circuitry detects user proximity and/or touch events on the trackpad, wherein the inductive sensing circuitry detects position and movement of a stylus on the trackpad, wherein the trackpad detects a user proximity and/or touch event used for selecting a window on said display, wherein the trackpad detects another user proximity and/or touch event or events used for repositioning and/or setting of the selected window, and wherein the trackpad detects stylus position and movement used to enter content in said window.
