Information handling devices (“devices”) come in a variety of forms, for example desktop or laptop computing devices, tablet computing devices, smart phones, and the like. Device users are increasingly relying on touch sensitive surfaces, e.g., a touch screen, to provide inputs, e.g., controlling inputs such as scrolling, or content inputs, such as providing handwriting inputs, etc. With advances in technology, even multiple users may provide simultaneous inputs to touch sensitive surfaces, e.g., while interfacing with larger touch screens to play a game, work on a project document, etc.
In summary, one aspect provides a method, comprising: activating, using a processor, a touch sensitive surface; accepting user inputs to the touch sensitive surface; detecting, using a processor, a deactivation event; and deactivating, using a processor, a portion of the touch sensitive surface such that the portion is unresponsive to touch input following detection of the deactivation event; wherein the deactivating deactivates one or more portions of the touch sensitive surface for one or more users; and wherein at least one other portion of the touch sensitive surface remains active.
Another aspect provides an information handling device, comprising: a touch sensitive surface; a processor operatively coupled to the touch sensitive surface; a memory device that stores instructions accessible to the processor, the instructions being executable by the processor to: activate the touch sensitive surface; accept user inputs to the touch sensitive surface; detect a deactivation event; and deactivate a portion of the touch sensitive surface such that the portion is unresponsive to touch input following detection of the deactivation event; wherein to deactivate comprises deactivating one or more portions of the touch sensitive surface for one or more users; and wherein at least one other portion of the touch sensitive surface remains active.
A further aspect provides a product, comprising: a storage device having code stored therewith, the code being executable by a processor and comprising: code that activates, using a processor, a touch sensitive surface; code that accepts user inputs to the touch sensitive surface; code that detects, using a processor, a deactivation event; and code that deactivates, using a processor, a portion of the touch sensitive surface such that the portion is unresponsive to touch input following detection of the deactivation event; wherein the code that deactivates further deactivates one or more portions of the touch sensitive surface for one or more users; and wherein at least one other portion of the touch sensitive surface remains active.
The foregoing is a summary and thus may contain simplifications, generalizations, and omissions of detail; consequently, those skilled in the art will appreciate that the summary is illustrative only and is not intended to be in any way limiting.
For a better understanding of the embodiments, together with other and further features and advantages thereof, reference is made to the following description, taken in conjunction with the accompanying drawings. The scope of the invention will be pointed out in the appended claims.
It will be readily understood that the components of the embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations in addition to the described example embodiments. Thus, the following more detailed description of the example embodiments, as represented in the figures, is not intended to limit the scope of the embodiments, as claimed, but is merely representative of example embodiments.
Reference throughout this specification to “one embodiment” or “an embodiment” (or the like) means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” or the like in various places throughout this specification are not necessarily all referring to the same embodiment.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that the various embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, et cetera. In other instances, well known structures, materials, or operations are not shown or described in detail to avoid obfuscation.
When using a touch screen device one problem that sometimes occurs is inadvertent touches are registered, e.g., when the user accidentally makes contact with the screen in an area he or she did not intend to touch. This often happens when using a stylus or finger to draw on the screen and the palm of the hand rests on the touch screen. With newer multi-touch touch screens this also occurs is when multiple people are sharing a large screen device and one user accidentally touches the screen when a different user is trying to accomplish a task. In such situations, it would be advantageous from a user experience standpoint for the user to be able to deactivate areas of the touch screen where he or she does not want touches to register.
Currently there exists software that is able to distinguish between different types of touches, e.g., a finger touch and a palm resting on the touch screen surface. Such palm rejection software is common in certain touch screen products. There also exist software solutions that allow a user to disable the touch function for the entire screen at any given time. What is missing is a simple way for a user to control specific areas of a touch screen and temporarily designate them as either active or inactive.
Accordingly, an embodiment provides a touch sensitive surface, e.g., a touch screen, which may be partially deactivated. For example, a user may deactivate a portion of the touch screen via providing inputs to delimit area(s) of the touch screen that are to be deactivated. Similarly, an embodiment may facilitate use of touch screen in a multi-user environment, e.g., via permitting the assignment of area(s) to specific users, whereas touch inputs outside of assigned areas will not register as inputs. It should be noted that although the term “deactivate” (or “inactivate”) is used throughout, this does not necessarily mean that the touch sensitive surface is no longer active at all or no longer active from the perspective of sensing touch inputs. Rather, an embodiment may filter touch inputs that are sensed in a deactivated area, e.g., filtering out touch inputs to the deactivated area.
The illustrated example embodiments will be best understood by reference to the figures. The following description is intended only by way of example, and simply illustrates certain example embodiments.
While various other circuits, circuitry or components may be utilized in information handling devices, with regard to smart phone and/or tablet circuitry 100, an example illustrated in
There are power management chip(s) 130, e.g., a battery management unit, BMU, which manage power as supplied, for example, via a rechargeable battery 140, which may be recharged by a connection to a power source (not shown). In at least one design, a single chip, such as 110, is used to supply BIOS like functionality and DRAM memory.
System 100 typically includes one or more of a WWAN transceiver 150 and a WLAN transceiver 160 for connecting to various networks, such as telecommunications networks and wireless Internet devices, e.g., access points. Additional devices 120 are commonly included. System 100 often includes a touch screen 170 for data input and display/rendering, e.g., receiving content and navigation inputs via a pen or stylus, as further described herein. System 100 also typically includes various memory devices, for example flash memory 180 and SDRAM 190.

The system, upon power on, may be configured to execute boot code 290 for the BIOS 268, as stored within the SPI Flash 266, and thereafter processes data under the control of one or more operating systems and application software (for example, stored in system memory 240). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS 268. As described herein, a device may include fewer or more features than shown in the system of
Information handling device circuitry, as for example outlined in
Referring to
For example, an embodiment permits a user to create an active touch area and a deactivated touch area, for example by detecting that the user has formed a virtual bezel. As illustrated in
This active box 402 continues to accept user inputs and may be moved around the screen. The dimensions of the active box 402 may be changed, e.g., by simply touching the edges of the box 402 and dragging in or out accordingly, e.g., similar to moving a virtual bezel. An embodiment thus provides the ability to edit the placement and dimensions of the active area. As illustrated in
A user may remove the inactive area 403 by providing an activation event, e.g., via grabbing the horizontal and vertical edges of the active area 402 and “throwing” them outward (or providing another predetermined gesture or input) to make the entire screen active again.
For text-specific fields within an active area 402, a double-tap on the field may activate that particular text field (and only that field) for input by the user. Double-tapping on another text field may move the focus and ability to edit to the next field, leaving the previous field inactive once again. An embodiment also provides an ability to control designated active 402 and inactive 403 areas with a timer function. For example, a user may provide a deactivation event that includes timing such that a designated area will only be touch-active at certain times. This capability may be useful for example in a school setting where timed exams administered on touch screen devices need to deactivate the entire screen or designated areas of the screen from receiving touch input once a pre-set time limit expires.
As described herein, the deactivation event may comprise a user specific designation event. For example, user-specific (including stylus/pen-specific) restrictions in applications like games, etc., may be utilized. For example, a user-specific designation may be utilized such that user A may only interact with certain areas or objects on the screen (e.g., user A game pieces in a chess game, as an example), but cannot edit or manipulate user B's pieces.
Other possible applications of utilizing user specific designations may include but are not necessarily limited to designating areas in formatted documents, e.g., legal documents that require digital signatures, use in games or drawing programs where multiple users would be touching the screen at the same time, or drawing programs where it is often necessary for a user to rest his or her fingers or palm on the screen for added precision.
By way of example,
Accordingly, an embodiment permits a user to deactivate certain areas within a touch sensitive surface while continuing to utilize other active areas of the touch sensitive surface. While specific examples have been provided herein, it will be appreciated by one having ordinary skill in the art that more than one active/inactive designation may be utilized, more than one active and more than one inactive area formed, as well as providing user specific designation or assignments to particular areas. The adjustment of the active area(s) of the touch sensitive surface furthermore may not be static, but dynamic such that areas may switch from active to inactive and vice versa, e.g., responsive to user inputs, underlying application events, etc.
As will be appreciated by one skilled in the art, various aspects may be embodied as a system, method or device program product. Accordingly, aspects may take the form of an entirely hardware embodiment or an embodiment including software that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects may take the form of a device program product embodied in one or more device readable medium(s) having device readable program code embodied therewith.
It should be noted that the various functions described herein may be implemented using instructions stored on a device readable storage medium such as a non-signal storage device that are executed by a processor. A storage device may be, for example, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples of a storage medium would include the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a storage device is not a signal and “non-transitory” includes all media except signal media.
Program code embodied on a storage medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, et cetera, or any suitable combination of the foregoing.
Program code for carrying out operations may be written in any combination of one or more programming languages. The program code may execute entirely on a single device, partly on a single device, as a stand-alone software package, partly on single device and partly on another device, or entirely on the other device. In some cases, the devices may be connected through any type of connection or network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made through other devices (for example, through the Internet using an Internet Service Provider), through wireless connections, e.g., near-field communication, or through a hard wire connection, such as over a USB connection.
