Abstract

A computer-implemented method is performed at a multifunction device with a display and a touch-sensitive surface. The method includes detecting multiple input gestures by a user, beginning with an initial input gesture. For each input gesture after the initial input gesture, the method scrolls information on the display at a respective scrolling speed. The respective scrolling speed is determined based on the respective input gesture movement speed in the input gesture and a movement multiplier. The method determines whether the respective input gesture meets one or more swipe gesture criteria, and determines whether the respective input gesture meets one or more successive gesture criteria. When the input gesture meets the one or more swipe gesture criteria and the one or more successive gesture criteria, the method updates the movement multiplier in accordance with one or more movement multiplier adjustment criteria.

Description

    RELATED APPLICATIONS
  • This application claims priority to U.S. Provisional Patent Application No. 61/160,680, “Accelerated Scrolling for a Multifunction Device,” filed on Mar. 16, 2009, which is incorporated by reference herein in its entirety.
  • TECHNICAL FIELD
  • The disclosed embodiments relate generally to electronic devices with touch-sensitive surfaces and displays that present scrollable information to users. More particular, the disclosed embodiments relate to accelerated scrolling of information on devices with touch sensitive surfaces.
  • BACKGROUND
  • Applications on multifunction devices may show information to a user, and the information may not all fit within the display of the multifunction device. For example, a multi-page electronic document may extend beyond the display. In this case, a user must scroll through the information.
  • Typical scrolling methods scroll through information based on finger movement, and the amount of scrolling is the same as the amount of finger movement. For example, when scrolling through an electronic contact list, the list may scroll through five contacts when the user's finger moves two centimeters.
  • When the information on the display of a multifunction device is lengthy, scrolling at a fixed rate is slow and inefficient. For example, it could take a very long time to scroll through a hundred page document or a contact list with several hundred contacts.
  • Accordingly, there is a need for multifunction devices with faster, more efficient methods and interfaces for scrolling information. Such methods and interfaces may complement or replace conventional methods for scrolling. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated multifunction devices, such methods and interfaces conserve power and increase the time between battery charges.
  • SUMMARY

No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 206) may turn power to the device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.
  • The touch-sensitive touch screen 112 provides an input interface and an output interface between the device and a user. The display controller 156 receives and/or sends electrical signals from/to the touch screen 112. The touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.
  • A touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen 112 and the display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on the touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen 112 and the user corresponds to a finger of the user.
  • The touch screen 112 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen 112 and the display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif.
  • A touch-sensitive display in some embodiments of the touch screen 112 may be analogous to the multi-touch sensitive tablets described in the following U.S. patents: U.S. Pat.

No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.
  • The touch screen 112 may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 160 dpi. The user may make contact with the touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.
  • In some embodiments, in addition to the touch screen, the device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.
  • In some embodiments, the device 100 may include a physical or virtual click wheel as an input control device 116. A user may navigate among and interact with one or more graphical objects (e.g., icons) displayed in the touch screen 112 by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller 160 as well as one or more of the modules and/or sets of instructions in memory 102. For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen 112 and the display controller 156, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.
  • The device 100 also includes a power system 162 for powering the various components. The power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.
  • The device 100 may also include one or more optical sensors 164. FIGS. 1A and 1B show an optical sensor coupled to an optical sensor controller 158 in I/O subsystem 106. The optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module 143 (also called a camera module), the optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of the device 100, opposite the touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.
  • The device 100 may also include one or more proximity sensors 166. FIGS. 1A and 1B show a proximity sensor 166 coupled to the peripherals interface 118. Alternately, the proximity sensor 166 may be coupled to an input controller 160 in the I/O subsystem 106. The proximity sensor 166 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables the touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user's pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state.
  • The device 100 may also include one or more accelerometers 168. FIGS. 1A and 1B show an accelerometer 168 coupled to the peripherals interface 118. Alternately, the accelerometer 168 may be coupled to an input controller 160 in the I/O subsystem 106. The accelerometer 168 may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers.
  • In some embodiments, the software components stored in memory 102 (e.g., in a computer readable storage medium of memory 102) may include an operating system 126, a communication module (or set of instructions) 128, a contact/motion module (or set of instructions) 130, a graphics module (or set of instructions) 132, a text input module (or set of instructions) 134, a Global Positioning System (GPS) module (or set of instructions) 135, and applications (or set of instructions) 136.
  • The operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.
  • The communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by the RF circuitry 108 and/or the external port 124. The external port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices.
  • The contact/motion module 130 may detect contact with the touch screen 112 (in conjunction with the display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). The contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module 130 and the display controller 156 detects contact on a touchpad. In some embodiments, the contact/motion module 130 and the controller 160 detects contact on a click wheel.
  • The contact/motion module 130 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture comprises detecting a finger-down event followed by detecting a finger-up event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface comprises detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up event.
  • In some embodiments, the contact/motion module 130 (FIG. 3) detects finger swipe gestures, and implements scrolling of information on the display (112, FIG. 2; 340, FIG. 3) of the device when one or more finger swipe gestures made with a user's finger meet predefined criteria. Scrolling information on a display is described below with reference to FIGS. 6A-6E.
  • The graphics module 132 includes various known software components for rendering and displaying graphics on the touch screen 112 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.
  • In some embodiments, the graphics module 132 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.
  • The text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).
  • The GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).
  • The applications 136 may include the following modules (or sets of instructions), or a subset or superset thereof:
      • a contacts module 137 (sometimes called an address book or contact list);
      • a telephone module 138;
      • a video conferencing module 139;

  • FIGS. 5A-5E illustrate an exemplary series of finger gestures on a touch-screen device according to one embodiment. FIG. 5A show six items of information 502-1 to 502-6 on User Interface 200. These items may be items within a scrollable list of items. FIG. 5B illustrates an initial finger gesture, showing information item 502-6 at its initial location 502-6-a and at its final location 502-6-b after scrolling. The dotted circle 504A identifies the initial location of the user's finger during a first swipe, and dotted circle 504B identifies the final location of the user's finger during the first swipe. In FIG. 5B the amount of scrolling corresponds to the amount of finger movement. FIG. 5C illustrates a second finger gesture, with scrolling similar to FIG. 5B. FIGS. 5D and 5E illustrate accelerated scrolling during subsequent finger gestures, with the movement of information items on the display greater than the movement of the user's finger. The item of information at the bottom of the display is scrolled to the top while the user's finger moves part way up the display. FIGS. 5A-5E will be described more fully below with respect to FIGS. 6A-6E.
  • FIGS. 5F-5H illustrate exemplary ways to increase a finger movement multiplier. FIG. 5F illustrates the case where the finger movement multiplier changes in an instant from 1.0 to 1.5. FIGS. 5G and 5H illustrate cases where the increase in the finger movement multiplier is implemented gradually during a swipe gesture. FIGS. 5F-5H will be described in more detail below with respect to FIGS. 6A-6E.
  • FIG. 5I illustrates a partial time line with a series of finger gestures. FIG. 5I also illustrates the time period between two successive finger gestures. FIG. 5I will be described in more detail below with respect to FIGS. 6A-6E.
  • FIGS. 6A-6E are flow diagrams illustrating a method of scrolling in accordance with some embodiments. The method 600 is performed at a multifunction device (e.g., device 100, FIG. 2) with a display and a touch-sensitive surface. Some operations in method 600 may be combined and/or the order of some operations may be changed. In some embodiments, the contact/motion module 130 (FIG. 3) detects finger swipe gestures, and implements the scrolling of information on the display (112, FIG. 2; 340, FIG. 3) of the device in accordance with one or more of the methods illustrated in FIGS. 6A-6E.
  • In some embodiments, the touch-sensitive surface is separate from the display. For example, in some embodiments, the touch-sensitive surface is a touch pad that is a component of the multifunction device, but separate from the display.
  • In some embodiments, the method is performed by a portable multifunction device with a touch screen display (e.g., portable multifunction device 100 in FIG. 2). In these embodiments, the aforementioned touch-sensitive surface is on the device's display. In other words, the multifunction device's display is a touch screen display (e.g., display 112, FIG. 2).
  • As described below, the method 600 provides an intuitive way to efficiently scroll information on a display. Method 600 employs various criteria to determine when to accelerate scrolling, thus enabling a user to reach desired information more quickly. The method reduces the cognitive burden on a user when scrolling, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to scroll information more quickly and efficiently conserves power and increases the time between battery charges.
  • A multifunction device with a display and a touch-sensitive surface detects (602) a series of finger gestures by a user's finger on the touch-sensitive surface. The series begins with an initial finger gesture. In some embodiments, method 600 scrolls (606) information on the display at an initial scrolling speed for the initial finger gesture. In some embodiments the initial scrolling speed is based on the initial finger movement speed in the initial finger gesture and a default finger movement multiplier. For example, the default value for the finger movement multiplier may be 1.0. In some embodiments, method 600 determines (608) whether the initial finger gesture is a “swipe.” This determination is based on one or more swipe gesture criteria. Exemplary criteria to determine whether a finger gesture is a swipe are described below at 628-634 in the flow diagram (FIG. 6C).
  • For each subsequent finger gesture, method 600 scrolls (612) information on the display at a scrolling speed that is determined by the finger movement speed during the finger gesture and the finger movement multiplier. For example, when the finger movement multiplier is 1.0, the scrolling on the display is at the same speed as the finger. If the finger movement multiplier is 2.0, the scrolling speed is twice as fast as the speed of the finger.
  • Described from another perspective, the amount of scrolling during a finger gesture is determined by the amount of finger movement during the finger gesture and the finger movement multiplier.
  • In some embodiments scrolling continues even after the user's finger lifts off the touch sensitive surface. For example, scrolling of the information on the display may be governed by a momentum and friction model, in which the displayed information is treated as having a certain speed (or momentum) at the end of each swipe gesture, and therefore continues to scroll after the swipe gesture. In the absence of any subsequent finger gestures that interrupt or further accelerate the scrolling, the scrolling slows down in accordance with a model, such as a friction model, or in accordance with a predefined amount of deceleration until either the scroll speed reaches a terminal value (e.g., zero), or the end of the displayed information is reached.
  • FIGS. 5A-5E illustrate the scrolling according to some embodiments.
  • FIG. 5A illustrates an initial screen with items of information prior to a series of finger gestures. FIGS. 5B-5E illustrate subsequent finger gestures in the series. FIGS. 5B and 5C illustrate scrolling of a list of items, with a finger movement multiplier of 1.0. In each of these figures the item of information initially at the bottom (502-6-a and 502-15-a, respectively) scrolls to the top (502-6-b and 502-15-b, respectively) during a finger gesture. The dotted circles in FIGS. 5B and 5C indicate the position of the user's finger at the beginning and end of the finger gesture, thereby indicating the movement of the user's finger during those gestures (e.g., the first and second vertical swipes in a series of swipes). In FIG. 5B the user's finger moves from 504A to 504B, and in FIG. 5C the user's finger moves from 506A to 506B. In each of these figures the amount of scrolling matches the amount of finger movement.
  • FIGS. 5D and 5E illustrate accelerated scrolling according to some embodiments in response to successive swipe finger gestures by a user's finger. In these figures the information initially at the bottom (502-80-a and 502-200-a, respectively) scrolls to the top (502-80-b and 502-200-b, respectively) during a portion of the finger gesture. The dotted circles in FIGS. 5D and 5E illustrate the movement of the user's finger during the course of two successive swipe finger gestures. In FIG. 5D the user's finger moves from 508A to 508B, and in FIG. 5E the user's finger moves from 510A to 510B. In FIGS. 5D and 5E information formerly at the bottom of the display has scrolled all the way to the top in response to a finger movement whose length is smaller than the distance traveled by the respective information items (508A/508B, 510A/510B), thus illustrating accelerated scrolling. FIG. 5E illustrates greater accelerated scrolling than FIG. 5D because FIG. 5E shows greater scrolling relative to the amount of finger movement.
  • In some embodiments the information displayed is a list (614). For example, the information displayed may be a list of contacts, a list of calendar entries, a list of content in a media player, a list of electronic messages (e.g., email messages), a list of applications, a drop-down list, a list of search results, a list of files, or the like.
  • In some embodiments the information is an array (616). For example, the information may be an array of thumbnail images in an image management application.
  • In some embodiments the information is an electronic document (618). For example, the information may be an electronic book, a web page, a PDF file, a word processing document, an electronic presentation, a spreadsheet, or the like. Any electronic information whose rendering as an image is larger than the user's display will typically be scrolled to view different portions of the information.
  • There are a variety of ways to specify how the finger movement speed is calculated. In some embodiments, the finger movement speed is the average speed of the user's finger during the finger gesture (620). In some embodiments the finger movement speed is the speed of the user's finger at the end of the finger gesture (622). For example, once the user's finger lifts off of the touch sensitive surface (thus ending the finger gesture), the speed of the user's finger at lift off, or over a time interval immediately prior to detecting lift off, is used as the finger movement speed. When using a time interval immediately prior to lift off, exemplary time intervals may be 20 milliseconds, 50 milliseconds, or 100 milliseconds. In other embodiments, the finger movement speed may be determined by the average speed of the user's finger during a time interval that is not at the end of the finger gesture. In yet other embodiments, the finger movement speed may be determined during multiple successive time intervals, each having a fixed duration (e.g., 20 to 50 milliseconds).
  • In some embodiments the finger movement multiplier is determined based on a series of finger gestures (624). Each of the finger gestures in the series must satisfy certain swipe gesture criteria and certain successive gesture criteria (624). In some embodiments the initial (default) value for the finger movement multiplier is 1.0, and may increase as subsequent finger gestures meet both the swipe gesture criteria and the successive gesture criteria. In some embodiments, the finger movement multiplier resets to a default value when a subsequent finger gesture fails to satisfy either the swipe gesture criterion or the successive gesture criterion.
  • For each finger gesture after the initial finger gesture, method 600 determines (626) whether the finger gesture satisfies certain swipe gesture criteria. In some embodiments one of the swipe gesture criteria is a requirement that the finger gesture occurs in a single direction (628). For example, the finger gesture may be an upward swipe, a downward swipe, a right-to-left swipe, a left-to-right swipe, or a diagonal swipe where the user's finger moves substantially in a single direction.
  • Because scrolling is generally limited to specific directions, a human user need not be precise about the direction of finger movement. For example, an upward swipe may include portions who direction of movement differs from vertical by as much as ±10°, or in other embodiments by as much as ±20°. During such a finger gesture the user's finger moves in substantially a single direction: upward (i.e., with a predefined deviation, such as ±10°, and which does not exceed)±20°.
  • In some embodiments one of the swipe gesture criteria is a requirement that the speed of the user's finger stays above a specified minimum speed value during the finger gesture (630). For example, the specified minimum speed value could be 150 mm/sec. If the speed of the user's finger varies between 170 mm/sec and 250 mm/sec during the finger gesture, then it would satisfy the criterion. However, if the user's finger speed is only 140 mm/sec at some point in the finger gesture, the finger gesture would not satisfy the criterion. Of course, whether a finger gesture satisfies this criterion depends on the specified minimum speed value.
  • In some embodiments one of the swipe gesture criteria is a requirement that the speed of the user's finger is above a specified minimum final value at the end of the finger gesture (632). For example, once the user's finger lifts off of the touch sensitive surface, the speed of the user's finger at lift off, or over a time interval immediately prior to detecting lift off, must be above the specified minimum final value. When using a time interval immediately prior to lift off, exemplary time intervals may be 10 milliseconds, 20 milliseconds, 50 milliseconds, or 100 milliseconds.
  • In some embodiments one of the swipe gesture criteria is a requirement that the average speed of the user's finger during the finger gesture is above a specified minimum average value (634). For example, the specified minimum average value could be 150 mm/sec. Suppose the speed of the user's finger varies between 140 mm/sec and 200 mm/sec, with an average speed of 175 mm/sec. Even though the user's finger had a speed below 150 mm/sec during part of the finger gesture, the finger gesture satisfies the criterion because the average speed of 175 mm/sec was above the minimum 150 mm/sec.
  • For each finger gesture after the initial finger gesture, method 600 determines (636) whether the finger gesture satisfies certain successive gesture criteria. In some embodiments one of the successive gesture criteria is a requirement that the elapsed time between the end of the prior finger gesture and the beginning of the current finger gesture is less than or equal to a predefined maximum elapsed time (638). In one embodiment, the predefined maximum elapsed time is 1 second. In some other embodiments, the predefined maximum elapsed time is a fixed value equal to at least 0.6 seconds and that is not larger than 1.5 seconds. FIG. 5I illustrates two sequential finger gestures, and the elapsed time between the finger gestures is the time between t4 and t5. When the elapsed time between t4 and t5 exceeds the predefined maximum elapsed time, the finger gesture does not satisfy the criterion.
  • In some embodiments one of the successive gesture criteria is a requirement that the direction of the prior finger gesture is substantially the same as the direction of the current finger gesture (640). In some embodiments the directions of two finger gestures are substantially the same if their directions are both within a predefined number of degrees (e.g., ±5°, ±10°, or ±20°) of the same axial direction (i.e., vertically up, vertically down, horizontally left, or horizontally right). For example, if the maximum allowed deviation is 15 degrees, and a first finger gesture is 10 degrees to the left of vertically up, and the second finger gesture is 8 degrees to the right of vertically up, the “same direction” successive gesture criterion is met because both are within the allowed deviation of the vertically up direction. In some embodiments the angle of a finger gesture may be measured by drawing a line between the starting and ending points of the finger gesture, and determining the angle of that line within a coordinate system. In some embodiments the angle of a finger gesture may be determined by the movement of the finger at the end of the finger gesture, or during an interval of time just before the end of the finger gesture.
  • For each finger gesture after the initial finger gesture, method 600 updates (642) the finger movement multiplier according to finger movement multiplier adjustment criteria when the finger gesture satisfies the swipe gesture criteria and the successive gesture criteria. FIGS. 5F-5H illustrate exemplary ways that the finger movement multiplier may be adjusted during the finger gesture. FIG. 5F illustrates an embodiment where the finger movement multiplier changes in an instant (e.g., from a value of 1.0 to 1.5) at the beginning of the finger gesture. In alternative embodiments, the finger movement multiplier changes in an instant at the end of the finger gesture, or at some point in the middle of the finger gesture. In these embodiments the change to the finger movement multiplier is not gradual because it instantly changes from the old value to the new value.
  • In some embodiments updating the finger movement multiplier occurs gradually during the finger gesture (644). That is, updates to the finger movement multiplier occur so that the value of the finger movement multiplier changes gradually during the finger gesture. For example, the finger movement multiplier may increase by 0.002 each millisecond during a finger gesture, up to a predefined maximum increase (e.g., 0.5) per finger gesture. A gradual change to the finger movement multiplier can reduce the cognitive burden on the user by providing a smoother adjustment to the scrolling speed. Exemplary methods of gradually increasing the finger movement multiplier include linearly increasing the finger movement multiplier (646) during the finger gesture (e.g., the increase in multiplier may be a linear function of the distance traveled by the user's finger during the finger gesture, until a predefined maximum increase in the finger movement multiplier is reached), and incrementally increasing the finger movement multiplier (648) multiple times during the finger gesture (e.g., the finger movement multiplier may be increased by 0.05, or 0.10, each time the user's finger moves a predefined distance during the finger gesture, until a predefined maximum increase in the finger movement multiplier is reached). The finger movement multiplier vs. time graph in FIG. 5G shows how the finger movement multiplier could change during a finger gesture in embodiments where the finger movement multiplier is linearly increasing. The finger movement multiplier vs. time graph in FIG. 5H shows how the finger movement multiplier could change during a finger gesture in embodiments where the finger movement multiplier increases incrementally multiple times. As FIG. 5H shows, each incremental increase of the finger movement multiplier occurs in an instant, but each increase is small (e.g., steps of 0.10), unlike the single change to the finger movement multiplier illustrated in FIG. 5F. One of skill in the art would recognize that there are many other ways to implement changes to the finger movement multiplier.
  • In some embodiments one of the finger movement multiplier adjustment criteria is a requirement that a specified minimum number of successive finger swipe gestures must occur prior to adjusting the finger movement multiplier from the default value (650). This criterion may reduce the likelihood of scrolling past information desired by the user due to accelerated scrolling, especially when the desired information is close to the information displayed prior to the initiation of scrolling. In some embodiments the default value for the finger movement multiplier is 1.0.
  • In some embodiments one of the finger movement multiplier adjustment criteria is a requirement that adjustment of the finger movement multiplier is limited to a specified maximum value (652). For example, in some embodiments the maximum value of the finger movement multiplier is 3.0. If the finger movement multiplier might otherwise go above this value based on the other criteria, this criterion would limit the finger movement multiplier to 3.0.
  • In some embodiments, finger movements in the above described embodiments may be replaced with stylus movements or movements of any other input device capable of being used to produce a gesture. Furthermore, in some embodiments, finger movements may include movements of a user's finger or hand over a touch and hover sensitive surface.
  • The steps in the information processing methods described above may be implemented by running one or more functional modules in information processing apparatus such as general purpose processors or application specific chips. These modules, combinations of these modules, and/or their combination with general hardware (e.g., as described above with respect to FIGS. 1A, 1B and 3) are all included within the scope of protection of the invention.
  • The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
