Definitions

  • the present invention generally relates to a computed implemented method and an electronic device for providing visual feedback to a user when the edge of an object has been reached. More particularly, to a computed implemented method and an electronic device provided with an screen for providing visual feedback when a user reaches an edge of an object which is being displayed in said screen, during a manipulation operation on such object in which the user does not stops such operation but on the contrary continues performing it.
  • overlay needs to be understood as a visual element that, similarly to a curtain, is superimposed over a part of the content displayed in a graphic user interface.
  • translate and translation refer to the action of moving a document (a written or graphic information) which is being displayed in a graphic user interface though not visible in its entirety, either along one of the horizontal or vertical axes or obliquely, causing part of the document to be hidden through the edge(s) of the display area towards which the document is being translated and a hidden part of the document to appear from the opposite edge(s) of the display area and become visible.
  • scroll and scrolling refer to a translation limited along the horizontal or vertical axes, and in this sense they need to be understood in the frame of this document.
  • downsize and downsizing refer to the action of reducing the size with which a document is being displayed in a graphic user interface, which in case the document was originally not visible in its entirety cause an additional part of the document which was hidden to become visible.
  • This type of interfaces requires new interaction paradigms and presents new problems to solve in order to make them really usable and useful. For instance different alternatives to navigate through a document or through a list are possible, like dragging the document by touching the screen and moving the point of contact along the screen.
  • Patent Application US 201 1/010659 “Scrolling Method of Mobile Terminal And Apparatus For Performing The Same” describes a method to indicate that the last part of an object has been displayed as a result of an on-going scrolling operation by means of modifying a region of the object, for instance stretching or compressing said part of the object and afterwards restoring said region of the object to its original form.
  • Patent Application US 2009/07071 1 "Scrolling method of mobile terminal” describes a method that provides visual, audible and/or tactile feedback when the last item in a list is displayed as a result of a scrolling operation.
  • visual feedback are displaying a blank space at both ends of the displayed list; or displaying a border of a certain color; or coloring the last item in the list or the element adjacent to it.
  • audible feedback are a voice, a mechanical sound, an intermittent sound or a continuous sound.
  • An example of tactile feedback is the vibration of the device.
  • some of said methods comprise allowing the document or list to move beyond its limits, resulting in blank spaces being shown in the screen thus not making full use of the screen to display useful content. For example if a screen can display 10 items of a list at a time, and the method allows to show a blank space on 20% of the screen upon scrolling beyond the end of the list then just 8 items will be displayed until the list scrolls back in the other direction and the 2 additional items are shown.
  • the present invention aims to provide a method for providing visual feedback to a user when an edge of an object (e.g. end of a list of items or the edge of a document) has been reached when manipulating (e.g. scrolling, downscaling) said object, which is being displayed in a frame of the screen of an electronic device, i.e. on a delimited area of the screen of the electronic device prepared to display said object.

  • the invention provides in one aspect a computed implemented method for providing visual feedback to a user when the edge of an object has been reached, when translating said object along a delimited frame of the screen of an electronic device in which said object is being displayed.
  • said visual feedback extends an overlay from each of the edges of the frame of the screen that is reached by an edge of the object during the translation as long as the translation operation attempts to continue so that the object is not allowed to translate beyond its limits; and such overlays are hidden upon the user discontinuing the translation operation.
  • the translation action preferably can be a vertical or horizontal scrolling or on contrary an oblique translation.
  • the overlays are semitransparent to allow the part of the object underneath to be visualized. Moreover, the area of the overlays matches with the area of the blank space that would have appeared if the object had been let to move further inside the frame of the screen and each overlay is not extended over a predefined maximum width associated to each overlay.
  • the basic concept of this invention i.e. providing a visual feedback or indication to a user when the edge of an object has been reached is also applicable when downsizing said object within a delimited frame of the screen of an electronic device in which said object should be displayed and an edge of the object matches with the edge of the screen so that that edge of the object is adequately visible in the screen, without any part of the object hidden beyond that edge of the screen.

  • the overlays preferably are semitransparent to allow the part of the object underneath to be visualized and each overlay is not extended over a predefined maximum width associated to each overlay.
  • Overlays may be opaque, in which case they hide completely the part of the displayed content over which they are placed.

  • the device 100 interpreting the action requested by the user it runs the corresponding programs that control the graphic user interface to adapt the displayed content accordingly.
  • a type of manipulation to which this method is applicable is scrolling the object along the horizontal or vertical axes (201 ).
  • Such action can be triggered for instance by placing a finger (or similar tool) on the representation of the object in the display and, without losing contact with the screen, moving the finger along one of those axes.
  • the amount the document is translated is usually the same distance as the finger moves (1 :1 proportion), remaining thus the finger over the same part of the object, even though it moves across the display. But other proportions between the respective translation of the finger and the document are though possible. If such scrolling action is maintained during a long enough time then one of the edges of the object will be reached. In case the user does not get aware that this has happened there is a risk that the user pointlessly continues such scrolling action.
  • An appropriate signaling in the form of visual feedback is needed in order to make the user aware of the fact that an edge of the object has been reached and thus to avoid the user to unnecessarily continue performing such scrolling action and therefore to offer a more satisfactory usability to the user.

  • the width 308 of the overlay grows until it reaches its maximum width 309 at a certain point ( Figure 3D) and upon the user continuing the scrolling action the overlay is not extended further down but stays in the same position, as shown in Figure3E.
  • the overlay progressively hides through the upper edge of the frame 310 ( Figure 3F), until it disappears (Figure 3G).
  • FIG. 4A another type of manipulation that may result in two edges of the object reaching the edges of the frame is an oblique translation (Figure 4A), that is, any translation but those along the horizontal or vertical axes (401 ). If such translation action is maintained enough time then either one of the edges of the object will be reached or alternatively two of the edges will be reached simultaneously (402), depending on the position of the object within the frame and the direction of the translation action, with different set of steps being followed in each of the cases (403).
