## Title
Systems and methods for automatic disable of input devices

## Abstract

Systems, methods, apparatuses and computer program products configured to provide intelligent filtering techniques to reduce errant device inputs are described. For example, filtering out the data input from a touch pad while typing on the keyboard or operating with a pointing stick, even if the touch pad is sensing contact, is augmented by continuing to filter data from the touch pad until the contact on the touch pad ends.

## Background
BACKGROUND
Some electronic devices (for example, a laptop, a tablet, or a notebook style personal computer (PC)) have multiple input devices available to the user. The most common input devices are keyboard and pointing devices (for example, a mouse and/or a touchpad). Recently, the pointing device landscape has become more complex. In certain systems there are now multiple input pads responsive to touch, for example, one for finger touch (touchpad) and one for stylus touch (digitizer). No matter the particular array of input devices provided, users encountering electronic devices with multiple inputs may inadvertently press or touch some input devices (for example, unintentionally provide input through the touchpad or the touchpad buttons). The result is inadvertent or errant input that sometimes causes errors (for example, cursor activity appearing on the screen that does not match the user's expectations or intentions).

DETAILED DESCRIPTION
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 claims, but is merely representative of those 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, appearances 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 example embodiments. One skilled in the relevant art will recognize, however, that aspects 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.
The inventors have recognized that conventional solutions to inadvertent input problems essentially fall into two categories. The first involves manually turning off one of the input devices (for example, pressing Fn.+F8 keys). This is often an impractical solution for the user, as many times the user wishes to quickly switch back and forth between the input devices to complete a task. The second solution involves using a “palmcheck” filter that filters out potentially inadvertent contacts based on the size of the contact. The palmcheck filter ignores (filters out) inputs that are deemed too large to be caused by finger contact (a palm contact has a much larger imprint area than a finger tip contact on a touchpad).
Moreover, the inventors have recognized that larger, flush touchpad devices increase the potential for inadvertent contact with the touchpad. This situation creates inadvertent pointer movement, area selection, and/or scrolling via the touchpad contact. Inadvertent contacts may include but are not limited to: hands touching sides of a touchpad area while typing; hands touching sides of a touchpad area while operating a pointing stick/stylus/pen; brushing the sides of a touchpad area when moving hands across clamshell-style cover of a notebook computer; and tapping of the top area of a touchpad while using the buttons associated to a pointing stick.
The inventors have recognized that palmcheck and other conventional filters, such as those configured to ignore touchpad input while keyboard or pointing stick input is detected (typing/stick filters), are inadequate to address the certain problematic use contexts. One reason is that these filters tend to involve a timing component such that the filter is only active for a predetermined time and, responsive to the predetermined time expiring, the input device (for example, a touchpad) is re-enabled.
Accordingly, the inventors have recognized a need for improved techniques for filtering inadvertent contact, such as input with a touch pad. This is particularly true for pointing stick users who use a dual-point system, but rarely use the touchpad intentionally. For instance, while reading or thinking, a user may hold his/her hand position longer than a specified idle time, which can cause a lapse in the effectiveness of the conventional filter(s).
Embodiments therefore provide systems, methods, apparatuses and computer program products configured to provide intelligent filtering techniques to reduce errant inputs. Example embodiments are described herein with specific reference to filtering out inadvertent/unintentional/errant touchpad inputs; however, those having ordinary skill in the art will recognize that filtering of other input device(s) can be implemented consistent with the example embodiments described herein.
Embodiments are configured to ignore the data from the touch pad (for example, tapping, cursor movement, gestures, and/or scroll) while typing the keyboard or operating with a pointing stick, even if the touch pad is sensing contact (for example, by palm or fingers). Embodiments further continue ignoring the data from the touchpad until the contact on the touchpad ends (for example, the data is ignored until the user lifts his/her palm or fingers from the touchpad, removing the touchpad input). Effectively, this intelligently erases any time component related to the filter(s). Certain embodiments optionally invoke a “starting zone” requirement (discussed further herein) to re-enable full touchpad support. Certain embodiments furthermore utilize stored information such that if repeated errant input is detected, for example a starting zone requirement is not being met, according to a predetermined threshold, the system is configured to assume these user is preferentially not utilizing the touchpad. Thus, the system is configured to implement a hard disable of the touchpad, leaving the touchpad disabled (for example until manual intervention reactivates the touchpad).
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.
Referring to FIG. 1, an example electronic device 100 having multiple input devices (103-106) is illustrated. The example electronic device 100 is a laptop PC; however, as will be readily apparent to one having ordinary skill in the art, the example embodiments discussed herein are equally applicable to a variety of other electronic devices, such as notebook computers, tablet computers, smart phones, and the like.
The laptop PC 100 illustrated in FIG. 1 includes a display screen 102 and a keyboard 103. Moreover, included is a touchpad device (and associated buttons) 104 as well as a digitizer 105 that can be used in conjunction with a stylus/pen 106. The user can provide inputs to the laptop PC 100 through any of these input devices.
As an example use case illustrative of certain embodiments, consider a scenario where a user is browsing the Internet and happens upon a web page of particular interest and pauses for some significant amount of time (for example, five or ten minutes) to read the contents of the web page. The user may choose to scroll down the web page to view the remaining contents, for example by using a down arrow key of the keyboard 103. While reading and/or scrolling, the user may inadvertently rest his or her palm or finger(s) on the touchpad 104, providing an inadvertent touchpad input.
As discussed herein, such inadvertent touchpad input may be filtered out using a palmcheck style filter; however, such filters have a timing mechanism whereby the filter is turned off after a predetermined time. In the use scenario described, the user may continue to inadvertently provide input via the touchpad while continuing to read the contents of the web page. In such a case, conventional filters will fail to adequately filter continued inadvertent touchpad input.
Referring to FIG. 2, an example method for filtering continued, inadvertent touchpad inputs is illustrated. The system detects inputs 210 from one or more of the input devices. A first determination 220 is made to ascertain if errant input is being provided, such as by detecting multiple input devices are being used. If yes, embodiments are configured to filter 230 one or more of the input devices, as for example input detected from multiple input devices is indicative of inadvertent input. Otherwise, input is not deemed inadvertent and there is no need to provide a filter.
While any of a variety of methods can be utilized to detect inadvertent input (for example, detecting palm input, detecting input outside of a predetermined “start zone”, and the like), the described detection of multiple input devices being utilized is illustrative. A simple prioritization scheme can be used in such a case. Thus, while any of a variety of detection schemes and/or input filters can be applied, certain embodiments apply a prioritization filter, wherein certain input devices (for example, the keyboard 103) are prioritized over others (for example, the touchpad 104). Thus, in the scenario where keyboard input and touchpad input are detected at the same (or nearly the same) time, the keyboard input is utilized and the touchpad input is filtered out according to the priority scheme employed.
Referring again to the example use case of the user pausing to read the contents of a web page while scrolling with an arrow key of the keyboard 103, a continued touch pad input may cause difficulties for conventional filtering programs. As such, embodiments are configured to additionally detect the removal of touchpad input 240, such as by a user removing his or her hand/fingers/palm from the touchpad such that the touchpad input ceases. If the touchpad input is removed, the touchpad is re-enabled 250. Otherwise, embodiments are configured to maintain the filter to combat continued, inadvertent touchpad input.
Referring to FIG. 3, an example method of employing a hard disable of the touchpad is illustrated. A hard disable is defined as a semi-permanent disablement of the touchpad such that a manual intervention (for example, opening an application and changing a setting to re-enable or requiring a combined key press to re-enable) is required to re-enable the touchpad. This may be referred to herein as a “permanent” disablement of the touchpad; however, those having ordinary skill in the art will understand that this means semi-permanent, as discussed herein.
Similar to the flow illustrated in FIG. 2, the system detects inputs 310 from one or more of the input devices. A first determination 320 is made to ascertain if multiple input devices are being used. If yes, embodiments are configured to filter 330 one or more of the input devices, as input detected from multiple input devices is indicative of inadvertent input. Otherwise, input is not deemed inadvertent and there is no need to provide a filter. Again, any of a variety of detection schemes/filters can be applied.
Referring again to the example use case of the user pausing to read the contents of a web page while scrolling with an arrow key of the keyboard 103, a continued touch pad input may cause difficulties for conventional filtering programs. As such, embodiments are configured to detect the removal of touchpad input 340, such as by a user removing his or her hand from the touchpad and touchpad input ceasing. If the touchpad input is removed, the touchpad is re-enabled 350. Otherwise, embodiments are configured to maintain the filter to combat continued, inadvertent touchpad input. Subsequent to re-enabling the touchpad 350, however, certain embodiments are configured to increment a counter 360 to track pattern(s) of usage of the input devices. If it is determined that the counter exceeds a threshold value 370, a hard disable of the touchpad can be implemented 380. Otherwise, the system can continue to filter inputs as previously described herein.
The hard disable can be useful in a variety of contexts. For example, it may frequently occur that the user does not intentionally provide touchpad input but frequently provides inadvertent touchpad input. In such a scenario, the counter can be employed to disable the touchpad such that the filtering mechanism has proactively disabled the touchpad in such a way that if the user should want to use the touchpad, a manual intervention is required to re-enable the touchpad. The counter can be configured as desired and/or set to a multitude of default settings. For example, the counter can simply count up to a predetermined threshold, count to a predetermined threshold within a predetermined time period (for example, several minutes), or count to a predetermined threshold within a certain use context (for example, beginning at start up or log in). Thus, the counter simply needs to perform a tracking function useful for determining repeated inadvertent inputs such that a hard disable is desirably implemented.
Referring to FIG. 4, similar to the flows illustrated in FIGS. 2-3, the system detects inputs 410 from one or more of the input devices. A first determination 420 is made to ascertain if multiple input devices are being used. If yes, embodiments are configured to filter 430 one or more of the input devices, as input detected from multiple input devices is indicative of inadvertent input. Otherwise, input is not deemed inadvertent and there is no need to provide a filter. Again, any of a variety of detection schemes/filters can be applied.
Referring again to the example use case of the user pausing to read the contents of a web page while scrolling with an arrow key of the keyboard 103, a continued touch pad input may cause difficulties for conventional filtering programs. As such, embodiments are configured to detect the removal of touchpad input 440, such as by a user removing his or her hand from the touchpad and touchpad input ceasing. If the touchpad input is removed, the touchpad is re-enabled 450.
In certain embodiments, if a touch pad input is detected 460, it is determined if a start zone is used 460a. In FIG. 4 this is illustrated subsequent to re-enabling the touchpad; however, this is by no means a requirement. A start zone is an area of the touchpad (for example, a central area) considered indicative of intended touchpad input. If the start zone has not been used, embodiments are configured to increment a counter 460b to track pattern of usage of the input devices. In this case, the tracking counter indicates touchpad input detected but failure to properly use the start zone. This is indicative of unintended touchpad input, which triggers filtering of that input.
Repeated incidents of unintended touchpad input is indicative of a user that may not wish to have the touchpad enabled. Thus, if it is determined that the counter exceeds a threshold value 470, a hard disable of the touchpad can be implemented 480. Otherwise, the system can continue to filter inputs as described herein.
To briefly recap, embodiments are configured to automatically filter inadvertent inputs to an electronic device. Certain embodiments provide filtering of inadvertent inputs from an input device determined to be providing inadvertent inputs until such inadvertent input has ceased. Moreover, certain embodiments provide intelligent filtering, such that repetitive inadvertent inputs are taken as a clue to provide a more permanent (or semi-permanent) filtering, such as disabling a touchpad entirely (until the user provides some manual intervention to re-enable the touchpad).
It will be understood by those having ordinary skill in the art that the embodiments can be implemented with electronic devices having appropriately configured circuitry, such as a desktop or laptop computer system, notebook and tablet computer systems, smart phones, and the like.
