## Background
BACKGROUND
1. Technical Field
The present invention generally relates to data processing systems and in particular to touch screen displays in data processing systems.
2. Description of the Related Art
Touch screen displays have been increasing in popularity in recent years. Touch screens provide users with a convenient and efficient way to interact with a computer system. However, in order to maintain the level of convenience, efficiency, and even safety, maintaining the cleanliness of the touch screen is an important issue. There is some existing technology that provides a solution for the maintenance of the touch screen. A few solutions focus on maintaining the level of cleanliness based on the number of times a human makes contact with the screen. Other solutions utilize a measurement of the screen's opacity level to determine whether maintenance/cleaning is required. In addition, the maintenance action provided by some of the current solutions relies on the fixed action of a maintenance facility (i.e., a protection mechanism) that is integrated into the touch screen device. The current solutions place no particular focus on: (a) the detection of multiple inputs or objects coming into contact with a touch screen; or (b) the discernment of the type of inputs or objects; or (c) the type of maintenance actions needed in the particular type of environment.

DETAILED DESCRIPTION OF AN ILLUSTRATIVE EMBODIMENT
The illustrative embodiments provide a method, system, and computer program product for determining a level of cleanliness of a touch screen display, characterizing an object that makes contact with the screen, and initiating a specific maintenance action on the screen of a computer system, based on screen cleanliness and the object characterization. A screen diagnostic and maintenance (SDM) utility initiates a number of procedures to determine a set of characteristics of an object(s) that makes contact with the touch screen. Based on the results of the procedures, the SDM utility is able to characterize/identify the object. In addition, the SDM utility initiates the maintenance screen check(s) based on information stored in a maintenance configuration file(s). Based on the results of the maintenance check(s), data from the configuration file(s) and characterization of the object(s) which have made contact with the screen, the SDM utility determines the type of maintenance that is performed and the schedule of the maintenance action.
Implementation of the embodiments enables enhanced functionality for maintenance actions involving a touch screen display by: (1) allowing multiple input resolution; (2) allowing discernment of the various input; (3) allowing for fine granularity of maintenance actions; and (4) scheduling the maintenance actions to allow for some level of autonomy for the user. Additionally, the described maintenance actions (5) do not require that the detection and maintenance mechanisms be tightly coupled and integrated directly into the body of the device (as provided with a kiosk, for example).
In the following detailed description of exemplary embodiments of the invention, specific exemplary embodiments in which the invention may be practiced are described in sufficient details to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, architectural, programmatic, mechanical, electrical and other changes may be made without departing from the spirit or scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
Within the descriptions of the figures, similar elements are provided similar names and reference numerals as those of the previous figure(s). Where a later figure utilizes the element in a different context or with different functionality, the element is provided a different leading numeral representative of the figure number (e.g., 1xx for FIG. 1 and 2xx for FIG. 2). The specific numerals assigned to the elements are provided solely to aid in the description and not meant to imply any limitations (structural or functional) on the invention.
It is understood that the use of specific component, device and/or parameter names are for example only and not meant to imply any limitations on the invention. The invention may thus be implemented with different nomenclature/terminology utilized to describe the components/devices/parameters herein, without limitation. Each term utilized herein is to be given its broadest interpretation given the context in which that terms is utilized.
With reference now to FIG. 1, there is depicted a block diagram representation of an electronic device (which is illustrated as, but not limited to data processing system) configured with a multi-detection visual display screen (touch screen). Electronic device 100 comprises at least one processor or central processing unit (CPU) 101 connected to system memory 106 via system interconnect/bus 102. Also connected to system bus 102 is I/O controller 115, which provides connectivity and control for input devices, of which pointing device (or mouse) 116 and keyboard 117 are illustrated. I/O controller 115 is also connected to touch screen interface 112 which is connected to input/output touch screen display 118. Additionally, a multimedia drive 119 (e.g., CDRW or DVD drive) and USB (universal serial bus) hub 121 are illustrated, coupled to I/O controller. Multimedia drive 119 and USB hub 121 may operate as both input and output (storage) mechanisms. Electronic device 100 also comprises storage 107, within which data/instructions/code may be stored. Electronic device 100 further comprises maintenance logic 113 which provides a number of maintenance notifications, including one or more or a combination of the following: (1) a visual highlighting notification, which involves a visual change in the area (i.e., various grades of lighting or dimming); (2) a sound notification, such as an audio alert; (3) a sensory notification, which may include a complete usage restriction of the screen area; (4) a temperature notification/alert, whereby the area heats up or cools down, for example; and (5) a resolution resizing around the defective area. It is appreciated that the above list is not meant to imply any limitations on the type of notification that may be executed/implemented.
Electronic device 100 is also illustrated with a network interface device (NID) 125, with which electronic device 100 connects to one or more servers 133 via access network 130, such as the Internet. In the described embodiments, network 130 is a worldwide collection of networks and gateways that utilize the Transmission Control Protocol/Internet Protocol (TCP/IP) suite of protocols to communicate with one another. Of course, network access may also be provided via a number of different types of networks, such as an intranet, a local area network (LAN), a virtual private network (VPN), or other wide area network (WAN) other than the Internet, for example.
Notably, in addition to the above described hardware components of electronic device 100, various features of the invention are completed via software (or firmware) code or logic stored within memory 106 or other storage (e.g., storage 107) and executed by CPU 101. Thus, illustrated within memory 106 are a number of software/firmware components, including operating system (OS) 108 (e.g., Microsoft Windows®, a trademark of Microsoft Corp, GNU®/Linux®, registered trademarks of the Free Software Foundation and Linus Torvalds, or AIX®, a registered trademark of IBM), maintenance configuration (file) 109, maintenance records (file) 114, Object Recognition Facility 111, and screen diagnostic and maintenance (SDM) utility 110. In actual implementation, maintenance configuration (file) 109, maintenance records (file) 114, Object Recognition Facility 111, and SDM utility 110 may be combined as a single application collectively providing the various functions of each individual software component when the corresponding code is executed by the CPU 101. For simplicity, SDM utility 110 is illustrated and described as a stand alone or separate software/firmware component, which provides specific functions, as described below.
CPU 101 executes SDM utility 110 as well as OS 108, which supports the user interface features of SDM utility 110. In the illustrative embodiment, SDM utility 110 generates/provides several graphical user interfaces (GUI) to enable user interaction with, or manipulation of, the functional features of the utility (110). Among the software code/instructions provided by SDM utility 110, and which are specific to the invention, are: (a) code for detecting an occurrence of an object making contact with a touch screen display of a computer system; (b) code for characterizing/identifying the object that makes contact with the screen; and (c) code for initiating a specific maintenance action on the screen of the computer system. For simplicity of the description, the collective body of code that enables these various features is referred to herein as SDM utility 110. According to the illustrative embodiment, when CPU 101 executes SDM utility 110, electronic device 100 initiates a series of functional processes that enable the above functional features as well as additional features/functionality, which are described below within the description of FIGS. 2-3.
Those of ordinary skill in the art will appreciate that the hardware and basic configuration depicted in FIG. 1 may vary. For example, other devices/components may be used in addition to or in place of the hardware depicted. The depicted example is not meant to imply architectural limitations with respect to the present invention. The data processing system depicted in FIG. 1 may be, for example, an IBM eServer pSeries system, a product of International Business Machines Corporation in Armonk, N.Y., running the Advanced Interactive Executive (AIX) operating system or LINUX operating system.
In electronic device 100, SDM utility 110 detects contact from an object at touch screen display 118. SDM utility 110 characterizes the object to determine whether a maintenance action is required. Object recognition technology may be used to facilitate a characterization of the object. The characterization of the object is important since contact with certain objects may make touch screen 118 unusable. The types of objects making contact with the touch screen may take various forms which may include the following non-exhaustive list: (1) finger(s); (2) hand(s); (3) paper; (4) mist from the breath of a human being; (5) liquid; and (6) food. Sometimes multiple occurrences of contact by a particular object (e.g., a user's hands/fingers) with the touch screen are required to activate a maintenance action. However, a single occurrence of contact by another object (e.g., liquid) with the touch screen may be enough to activate a maintenance notification and/or action. For example, a drink/liquid spilling (see FIG. 2B) on touch screen 118 may create a greater level of urgency (i.e., may be assigned a higher level of maintenance priority) than bread crumbs coming into contact with touch screen 118. Furthermore, in this case, perhaps only one occurrence of a contact of this nature may be required to initiate a maintenance action. Thus, SDM utility 110 characterizes and distinguishes various types of object contact. SDM utility 110 refers to configuration record(s) 109 to determine the type of maintenance action required and the schedule of the action. For example, in the case of an object characterized as a “liquid spill”, the maintenance action may be to “clean the entire touch screen surface” and the schedule may be “immediately”.
In electronic device 100, the maintenance notification (and/or maintenance action) may take various forms. As utilized herein the term notification and action may refer to a same activity or different activity of the SDM utility 110. That is, a notification may be considered an action, and vice versa, while some actions are not notifications. For simplicity, the term “maintenance action” is used to represent both a notification and an action taken by the SDM utility 110. In particular, the maintenance action may be a combination of any of the following and may not be limited to: (1) a visual change in the area (i.e., various grades of lighting or dimming); (2) an audio alert; (3) a complete usage restriction of the screen area; (4) a temperature alert (i.e. the area heats up or cools down); and (5) a resolution resizing around the defective area. Multiple usage of the screen increases the likelihood for maintenance due to normal wear-and-tear and also creates a risk factor for germs/infection. Upon detection that the area of the screen is unclean as determined by a preset threshold level of cleanliness, the computer cross-references the user's priority setting for a cleaning action. A cleaning action may not be scheduled based on a number of factors which may include priority, time of day, etc.
SDM utility 110 may initiate maintenance action in the form of a screen protection mechanism. This mechanism may be executed by the computer based on certain configurable conditions. To avoid integration of this mechanism within the touch screen surface, SDM utility 110 may initiate communication with the protection mechanism via blue-tooth capability. Blue-tooth capability enables communication between the protection mechanism device and the computer in order to provide location details of the affected area to the protection mechanism device. SDM utility 110 may allow the protection mechanism to be applied to the full surface area. Alternatively, SDM utility 110 may indicate that a layered/sectional screen protection to specific areas is desired. The screen protection mechanism may include the following: (1) a transparent film to be applied to or removed from the surface; and (2) a wiper mechanism that dispenses cleaning material across the surface.
SDM utility 110 may employ an interaction or idleness level as a cue for scheduling a maintenance action on the screen surface. Based on the level of interaction or idleness, a time of day, ambient light or movement around the screen surface, a maintenance cycle may be initiated/scheduled.
FIG. 2A illustrates a touch screen display with multiple interacting users, according to one embodiment of the invention. Object-screen system 200 comprises touch screen display 118 with interacting user(s)/object(s) 201. In object-screen system 200, SDM utility 110 is capable of characterizing/identifying the object as a finger/hand. SDM utility 110 may further characterize “surface” characteristics of the object, such that a finger with grease is characterized differently from one with sweat (e.g., a sweaty or moist hand/finger). SDM utility 110 is able to distinguish between various types of contact in order to determine scheduling based on a configured priority and to select the most appropriate maintenance action. In one embodiment, for example, SDM utility 110 may employ Object Recognition Facility 111 to facilitate the characterization of object 201.
FIG. 2B is a block diagram of a multi-detection touch screen illustrating factors affecting the level of cleanliness of the screen and an example list of steps provided by SDM utility 110 to assist a user in resolving a screen maintenance issue, according to embodiments of the invention. Screen example 210 comprises touch screen 118. Disposed on touch screen 118 is liquid spill 211. A low pixel resolution area 212 of visual display on touch screen 118 is also illustrated. As provided within screen example 210, low resolution area 212 illustrates a section of the touch screen where clarity has been reduced. Additionally, a list with cleaning steps illustrated as maintenance list 213 is displayed on touch screen 218.
One application of low pixel resolution area 212 involves SDM utility 110 triggering an adjustment to the brightness, contrast, or degradation of screen resolution (bits per pixel) in an affected screen area. For example, with continual usage of the screen, SDM utility 110 may allow the area to continually change (degrade) in clarity. Thus, SDM utility 110 provides a visual indication of the level of dirtiness of that area of the screen 118, and responds by causing the area of the screen 118 to partially lose clarity. In extreme situations, SDM utility 118 may fully restrict visual display at a portion of the screen.
SDM utility 110 may alert the user to a possible problem (e.g., defective pixels, opaque/unclean section of the screen) with the surface screen via a constant indicator on or around the area affected. The constant indicator may include: (1) a visual effect such as highlighting or a display of icons, or arrows, on the screen; (2) a touch sensory mechanism by which the affected area becomes warmer or cooler to the touch; and (3) an audio sensory mechanism in which a sound becomes louder when a user/object gets within a certain proximity of the affected area.
SDM utility 110 may discover that pixels on the screen may be defective, after a maintenance action, for example. Consequently, SDM utility 110 may initiate a maintenance cycle to determine whether the pixel is actually “stuck” versus “dead” and then initiate the appropriate fix. As a maintenance action, SDM utility 110 may also provide temporary low resolution (212) of visual display on touch screen 118.
FIG. 3 is a flow chart illustrating a method by which the above processes of the illustrative embodiments are completed. Although the method illustrated in FIG. 3 may be described with reference to components shown in FIGS. 1-2, it should be understood that this is merely for convenience and alternative components and/or configurations thereof can be employed when implementing the various methods. Key portions of the methods may be completed by SDM utility 110 executing within electronic device 100 (FIG. 1) and controlling specific operations of/on electronic device 100, and the methods are thus described from the perspective of either/both SDM utility 110 and the multi-touch screen (118).
The process of FIG. 3 begins at initiator block 301 and proceeds to block 302, at which SDM utility 110 initiates an active mode. SDM utility 110 continuously monitors screen activity and initiates activities based on an external trigger (e.g., human contact) or internal triggers as a result of a pre-determined configuration. Furthermore, all user and computer system interaction via a touch screen proceeds without interruption by SDM utility 110.
At block 303, SDM utility 110 detects contact of an object(s) with the touch screen. SDM utility 110 initiates procedures to characterize the object, as shown at block 304. These procedures which reveal the properties of the object may include a number of the following: (1) a weight measurement; (2) a temperature measurement; (3) a location of the object; (4) an opacity level of the object; (5) further procedures (which may generate visual images/photographs of objects coming into contact with the touch screen, for example) to obtain data as inputs to an object recognition facility; and (6) multiple applications of the (measurement) procedures at various intervals in order to record changes in the object's properties over time. At block 305, SDM utility 110 identifies/characterizes the object based on the procedures to obtain the object characteristics. SDM utility 110 may determine whether the object is a liquid or a solid, for example, based on an identification of a set of properties of the object. The identification of the physical state may require multiple executions of a number of the preceding procedures. For example, a first measurement taken at one time interval and a second measurement taken subsequently may reveal the dynamic nature of a liquid, the location of which may change/expand as the liquid spreads across the touch screen. In addition, SDM utility 110 may be able to predict the manner in which the liquid spreads across the screen based on a computed viscosity of the liquid (obtained via the procedures/measurements).
At block 306, SDM utility 110 records, in a maintenance results file in the computer system, the occurrence of the contact of the characterized/identified object with the touch screen. Thus, SDM utility 110 is able to track a particular type of occurrence of object contact and provide a determination of the ability of the contact by the object with the touch screen to affect the level of screen cleanliness, based on the object characterization.
In addition to the measurement/maintenance procedures initiated by an external trigger, at a preset time period(s), SDM utility 110 initiates a number of maintenance screen checks, as shown at block 307. The timing of the maintenance checks are preset by configuration settings in a stored maintenance configuration file. The maintenance screen checks may be executed to determine a cleanliness level of the screen. A level of cleanliness may be determined by a reading(s) obtained via opacity sensors. The results of the maintenance checks are also recorded in the results file.
At block 308, SDM utility 110 performs an analysis to determine whether a maintenance action on the touch screen is required by utilizing a number of the following: (1) object characterization; (2) maintenance check results; and (3) maintenance configuration file(s). The object characterization and the maintenance check results may be stored in the maintenance results file(s). At decision block 309, SDM utility 110 determines whether a maintenance action(s) is required, based on the analysis results. If, at block 309, SDM utility 110 determines that a maintenance action(s) is required, the process moves to block 310, at which SDM utility 110 determines the specific type of maintenance action(s) required based on the configuration file(s) and/or maintenance results file. At block 311, SDM utility 110 enters a maintenance mode and initiates a specific maintenance action. In one embodiment, list 213 may be displayed on the visual display touch screen to provide a maintenance staff/user with a list of steps for completing maintenance action(s).
The maintenance action may take various forms and may be a combination of a number of other maintenance actions. These maintenance actions are outlined in the description of the figures. Once the maintenance action is completed, as shown at block 312, active mode resumes (i.e., the system returns to the normal state of operation), and the process returns to block 302 for continuous monitoring.
In the flow charts above, one or more of the methods are embodied as a computer program product in a computer readable medium or containing computer readable code such that a series of steps are performed when the computer readable code is executed on a computing device. In some implementations, certain steps of the methods are combined, performed simultaneously or in a different order, or perhaps omitted, without deviating from the spirit and scope of the invention. Thus, while the method steps are described and illustrated in a particular sequence, use of a specific sequence of steps is not meant to imply any limitations on the invention. Changes may be made with regards to the sequence of steps without departing from the spirit or scope of the present invention. Use of a particular sequence is therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
As will be further appreciated, the processes in embodiments of the present invention may be implemented using any combination of software, firmware, or hardware. As a preparatory step to practicing the invention in software, the programming code (whether software or firmware) will typically be stored in one or more machine readable storage mediums such as fixed (hard) drives, diskettes, optical disks, magnetic tape, semiconductor memories such as ROMs, PROMs, etc., thereby making an article of manufacture (or computer program product) in accordance with the invention. The article of manufacture containing the programming code is used by either executing the code directly from the storage device, by copying the code from the storage device into another storage device such as a hard disk, RAM, etc., or by transmitting the code for remote execution using transmission type media such as digital and analog communication links. The methods of the invention may be practiced by combining one or more machine-readable storage devices containing the code according to the present invention with appropriate processing hardware to execute the code contained therein. An apparatus for practicing the invention could be one or more processing devices and storage systems containing or having network access to program(s) coded in accordance with the invention.
Thus, it is important that while an illustrative embodiment of the present invention is described in the context of a fully functional computer (server) system with installed (or executed) software, those skilled in the art will appreciate that the software aspects of an illustrative embodiment of the present invention are capable of being distributed as a computer program product in a variety of forms, and that an illustrative embodiment of the present invention applies equally regardless of the particular type of media used to actually carry out the distribution. By way of example, a nonexclusive list of types of media includes recordable type (tangible) media such as floppy disks, thumb drives, hard disk drives, CD ROMs, DVDs, and transmission type media such as digital and analog communication links.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular system, device or component thereof to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims. Moreover, the use of the terms first, second, etc. do not denote any order or importance, but rather the terms first, second, etc. are used to distinguish one element from another.
