Description

APPARATUS AND METHOD FOR CONTROLLING A TOUCHSCREEN DISPLAY
FOR ONE HAND OPERATION
DESCRIPTION OF THE DISCLOSURE
Field of the Disclosure
[0001 ] This disclosure relates to human-computer interfaces in general and more particularly, to apparatus and method for controlling a touchscreen display for operation by one hand.
Background of the Disclosure
[0001 ] Electronic devices, such as portable electronic devices, have gained worldwide popularity due to their broad applications. Portable electronic devices may include, for example, smartphones, wireless personal digital assistants (PDAs), tablets, laptop computers with wireless or Bluetooth® capabilities, cellular telephones, etc. A user may use, for example, a smartphone to perform a variety of functions including making telephone calls, sending electronic messages, taking photos, reading articles, and other functions, by installing applications.
[0002] With the increasing number of applications, users tend to install more and more applications on their portable electronic devices. At the same time, users have started reading articles on their portable electronic devices. To accommodate users' various usages, manufacturers have brought into the market portable electronic devices that have relatively large touchscreens to enable rendering of more icons and contents. This, however, gives rise to problems for users who use one hand to operate portable electronic devices. For example, if a user uses the left hand to operate a portable electronic device and touches the touchscreen with the left thumb, the left thumb may not reach icons that are located far from the thumb location on the touchscreen.
[0003] To solve this problem, existing technologies relating to Human-Computer Interaction may provide a settings menu, by which a user sets his/her hand use preference. For example, if a user prefers to use the left hand while operating a portable electronic device, the user can set a corresponding user preference on the settings menu. After setting the user preference, icons on the user's portable electronic device touchscreen are displayed on the left hand side, such that the left thumb of the user can reach all the icons displayed on the touchscreen of the portable electronic device.
[0004] However, the existing technologies are not only complicated but also require presetting. Situations may arise in which a user has a need to use the right hand, even though the user usually uses the left hand to operate the user's portable electronic device. As an example, with the left hand being occupied, the user may need to instead use the right hand to operate the portable electronic device (e.g., to use an application on the portable device). Due to this need, the user may not have time to preset a user preference regarding which hand to use. As a result, a user may drop a portable electronic device while trying to reach an icon displayed on the touchscreen according to the preset preference and located far away from, e.g., the right thumb, while the left hand (corresponding to the preset) is occupied.

Alternatively, communication module 1 10 may include an Ethernet interface, a Wi-Fi interface, or a Bluetooth® interface to provide network communication with an Ethernet, a local area network (LAN), a wide area network (WAN), or any other computer networks. [0024] In exemplary embodiments, user 150 operates apparatus 100 through touchscreen 1 12 using, for example, hands or fingers. User 150 touches
touchscreen 1 12 with one or more fingers while operating apparatus 100. The one or more fingers of user 150 generate at least one point of contact on touchscreen 1 12. Processor 102 is configured to detect the coordinates of the point(s) of contact generated by the one or more fingers of user 150 according to the electronic signals generated by touchscreen 1 12. In further exemplary embodiments, if user 150 uses four fingers, processor 102 can be configured to determine whether user 150 is using the left hand or the right hand, based on respective coordinates of the points of contact generated by the four fingers on touchscreen 1 12.
[0025] In exemplary embodiments, processor 102 is configured to determine an invisible dividing line on touchscreen 1 12 ("dividing line"). According to the illustrated embodiments, processor 102 can be configured to determine a dividing line 200 in the middle of touchscreen 1 12 based on coordinate information, as shown in Fig. 2.
[0026] In one exemplary embodiment, processor 102 is configured to use dividing line 200 to determine whether user 150 is using the left hand or the right hand while operating apparatus 100. For example, if user 150 uses four fingers to touch
touchscreen 1 12, four points of contact are generated on touchscreen 1 12. In other embodiments, the total number of the points of contact generated by the fingers of user 150 can be greater or fewer than four, such that a different number of points of contact can be used to be the total number of the points of contact for determining whether user 150 is using the left hand or the right hand.
[0027] In one exemplary embodiment, as shown in Fig. 3A, if the respective coordinates of the four points of contact all fall to the left side of dividing line 200, processor 102 can be configured to determine that user 150 is using the right hand. As shown in Fig. 3B, if the respective coordinates of the four points of contact all fall to the right side of dividing line 200, processor 102 can be configured to determine that user 150 is using the left hand.
[0028] If processor 102 determines that user 150 is using the left hand, processor 102 determines that user 150 intends to use the left hand to operate touchscreen 1 12. Accordingly, in such a case, processor 102 is configured to cause touchscreen 1 12 to display an interface screen notifying user 150 that touchscreen 1 12 is set in a left-hand-operation mode. Similarly, if processor 102 determines that user 150 is using the right hand, processor 102 determines that user 150 intends to use the right hand to operate touchscreen 1 12. Accordingly, in such a case, processor 102 is configured to cause touchscreen 1 12 to display an interface screen notifying user 150 that touchscreen 1 12 is set in a right-hand-operation mode.
[0029] Thus, processor 102 is configured to control the display of
touchscreen 1 12 based on which hand of user 150 is being used to operate
touchscreen 1 12. According to the illustrated embodiments, touchscreen 1 12 displays graphic elements including, for example, icons. Figs. 4A and 4B show icons displayed on touchscreen 1 12 based on a result of determining which hand of user 150 is being used to operate touchscreen 1 12. In one exemplary embodiment, if user 150 is using the left hand, processor 102 is configured to control touchscreen 1 12 to display the icons in the bottom corner area on the left side of touchscreen 1 12 (Fig. 4A). In another exemplary embodiment, if user 150 is using the right hand, processor 102 is configured to control touchscreen 1 12 to display the icons in the bottom corner area on the right side of touchscreen 1 12 (Fig. 4B). The area for displaying the icons on
touchscreen 1 12, such as the bottom corner area on the left or the right side of touchscreen 1 12, is hereinafter referred to as the "icons display zone."
[0030] In exemplary embodiments, the size of the icons display zone is set within the range of the left thumb or the right thumb of user 150, such that the thumb of user 150 can reach all the icons displayed in the icons display zone. In one exemplary embodiment, processor 102 is configured to provide mechanisms that enable user 150 to set the size of the icons display zone. For example, user 150 can preset the size of the icons display zone on a settings menu. When processor 102 determines which hand user 150 is using, the icons display zone is adjusted according to the size user 150 has preset.
[0031 ] In exemplary embodiments, the shape of the icons display zone can be preset by user 150. For example, user 150 can preset the shape of the icons display zone to be fan-shaped. As another example, the shape of the icons display zone can be preset as square, circular, or another shape that enables the left or the right thumb of user 150 to reach all the icons displayed therein. According to the illustrated embodiments, processor 102 is configured to preset a fan-shaped icons display zone as a default icons display zone. For example, as illustrated above, if processor 102 determines that user 150 is using the left hand or the right hand, the fan-shaped icons display zone is located at the bottom corner of the left side or the right side of touchscreen 1 12, respectively.
[0032] In exemplary embodiments, processor 102 provides mechanisms that enable user 150 to preset the location of the icons display zone on touchscreen 1 12. In one exemplary embodiment, if user 150 is using the left hand, as shown in Fig. 5A, user 150 can preset the icons display zone along the middle of the left side of touchscreen 1 12. This preset can be made if, for example, user 150 prefers to place the left thumb in the middle of apparatus 100, and placing the icons display zone along the middle of the left side of touchscreen 1 12 facilitates user 150 reaching all the icons. In another exemplary embodiment, if user 150 is using the right hand, as shown in Fig. 5B, user 150 can preset the icons display zone along the middle of the right side of touchscreen 1 12.
[0033] In a further exemplary embodiment, if user 150 presets the location of the icons display zone, the shape of the icons display zone can be adjusted accordingly. For example, when the icons display zone is located at the bottom left or right corner of touchscreen 1 12, processor 102 can cause touchscreen 1 12 to display the icons display zone as fan-shaped. However, when the icons display zone is located along the middle of the left or right side of touchscreen 1 12, processor 102 can cause touchscreen 1 12 to display the icons display zone as approximately semicircular.
[0034] Additionally or alternatively, processor 102 can determine which hand user 150 intends to use by detecting whether user 150 presses a button. In one exemplary embodiment, apparatus 100 is configured to include a left button and a right button on both the left and the right side. If user 150 intends to use the left hand, user 150 presses the left button. Similarly, if user 150 intends to use the right hand, user 150 presses the right button. Functions regarding displaying the icons, and presetting the size, the location, and/or the shape of the icons display zones are the same as or similar to those exemplary embodiments provided above, so that further detailed description is omitted.
[0035] Fig. 6 illustrates a flow chart of a process 600 for controlling a display on touchscreen 1 12 for operation by one hand of user 150, according to an exemplary embodiment. Process 600 is performed by processor 102 according to computer- executable instructions stored in storage module 104. In one exemplary embodiment, user 150 starts process 600 by touching touchscreen 1 12. In the illustrated
embodiments, user 150 uses one or more fingers to touch touchscreen 1 12, and processor 102 is configured to detect that user 150 is touching touchscreen 1 12 (step 601 ).
[0036] In the illustrated embodiments, if user 150 touches touchscreen 1 12 with one or more fingers, at least one point of contact is generated on touchscreen 1 12. Processor 102 is configured to determine the number of points of contact generated by the one or more fingers of user 150. In one exemplary embodiment, user 150 may use four fingers to operate touchscreen 1 12. In this exemplary embodiment, processor 102 can be configured to determine whether there are four points of contact on touchscreen 1 12 generated by the four fingers of user 150 (step 602).
[0037] To filter noise (e.g., accidental touching or touching not by user 150), processor 102 is configured to wait for a predetermined period of time before confirming that there are four points of contact on touchscreen 1 12 generated by user 150. For example, processor 102 waits for 10ms before confirming whether there are four points of contact generated on touchscreen 1 12 (step 603).
[0038] If processor 102 confirms that there are four points of contact on touchscreen 1 12, processor 102 initiates a counter K at a value of 0 (step 604).
[0039] Processor 102 is configured to check the total number of the points of contact and their coordinates to determine whether user 150 intends to use the left hand or the right hand to operate touchscreen 1 12. For example, in the present embodiment, the predetermined total number of the points of contact is four, but another number can be the total number of the points of contact for determining whether user 150 intends to use the left hand or the right hand. If the total number of the points of contact is predetermined to be four, processor 102 can be configured to determine whether there are only four points of contact. In such a case, processor 102 can also be configured to detect the coordinates of the four points of contact to determine whether user 150 intends to use the left hand or the right hand to operate touchscreen 1 12 (step 605).
[0040] For example, if processor 102 determines there are four points of contact and that the respective coordinates of the four points of contact all fall to the left side of dividing line 200, i.e., on the left side of touchscreen 1 12, processor 102 determines that user 150 is using the right hand. As another example, if processor 102 determines there are four points of contact and that the respective coordinates of the four points of contact all fall to the right side of dividing line 200, i.e., on the right side of
touchscreen 1 12, processor 102 determines that user 150 is using the left hand.
[0041 ] However, if processor 102 determines that there are greater or fewer than a predetermined total number of points of contact detected on touchscreen 1 12, and/or the distribution of the points of contact is not consistent with a predetermined
distribution, processor 102 determines that an invalid operation or other operation has occurred (step 606). For example, if the predetermined total number of points of contact is four, and processor 102 determines that there are greater or fewer than four points of contact detected on touchscreen 1 12, processor 102 determines that an invalid operation or other operation has occurred. As another example, while
processor 102 determines that there are only four points of contact on touchscreen 1 12, if the respective coordinates of the four points of contact do not all fall on the left or the right side of touchscreen 1 12, processor 102 also determines that an invalid operation or other operation has occurred. In such case, the process flows to step 612.
[0042] If the predetermined total number of the points of contact for determining whether user 150 is using the left hand or the right hand is four, while processor 102 is determining whether there are only four points of contact on touchscreen 1 12, and the respective coordinates of the four points of contact all fall on one side of
touchscreen 1 12, the counter K is incremented by 1 ms (step 607). Processor 102 is configured then to determine whether the counter K has incremented to a
predetermined period of time, such as, for example, 50ms (step 608). If counter K has incremented to a number exceeding 50ms, processor 102 is configured to wait for a predetermined period of time, such as, for example, 10ms, before confirming that there are only four points of contact, and that the respective coordinates of the four points of contact all fall on one side of touchscreen 1 12 (step 609).
[0043] According to the illustrated embodiments, if processor 102 confirms that there are only four points of contact, and the respective coordinates of the four points of contact all fall on one side of touchscreen 1 12, processor 102 is configured to cause touchscreen 1 12 to generate an interface screen notifying user 150 that
touchscreen 1 12 has been set in either a left-hand-operation mode, or a right-hand- operation mode, depending on which hand user 150 is using when operating
touchscreen 1 12 (step 610).
[0044] Processor 102 is configured to control the display of icons on
touchscreen 1 12 based on which hand user 150 is using (step 61 1 ). For example, if user 150 is using the left hand to hold apparatus 100 and touch touchscreen 1 12, processor 102 can be configured to determine that user 150 intends to use the left hand to operate touchscreen 1 12, and accordingly cause touchscreen 1 12 to display icons on the left side of touchscreen 1 12. On the other hand, if user 150 is using the right hand to hold apparatus 100 and touch touchscreen 1 12, processor 102 can be configured to determine that user 150 intends to use the right hand to operate touchscreen 1 12, and accordingly cause touchscreen 1 12 to display icons on the right side of touchscreen 1 12. A detailed description regarding how the icons are displayed on touchscreen 1 12 has been provided above, and is therefore omitted.
[0045] Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. The scope of the invention is intended to cover any variations, uses, or adaptations of the invention following the general principles thereof and including such departures from the present disclosure as come within known or customary practice in the art. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
[0046] It will be appreciated that the present invention is not limited to the exact construction that has been described above and illustrated in the accompanying drawings, and that various modifications and changes can be made without departing from the scope thereof. It is intended that the scope of the invention only be limited by the appended claims.
