This application is related to and claims priority to U.S. Provisional Patent Application Ser. No. 61/187,520, filed Jun. 16, 2009 and entitled “Multi-Mode Handheld Electronic Device”, which is incorporated herein by reference.
Embodiments of the invention generally relate to the field of electronic devices and, more particularly, to a method and apparatus for context-based limitation of mobile device operation.
Mobile devices, including cellular phones, smart phones, personal digital computers, and other similar devices, allow for versatile operation in many different environments. Such devices allow for a great variety of different functions for various purposes, including business and personal use.
The versatility of mobile devices allows the opportunity for new activities in different environments. For example, many kinds of work activities that previously would have required a larger computer or an office setting may now be handled in many locations, or during travel. In addition, there are methods of communication using mobile devices that allow an individual to transfer and share documents and other data quickly and efficiently.
However, with the new functionality, persons may access mobile devices in inappropriate circumstances. For example, individuals may access cell phones or similar communications devices in circumstances that interfere with others, or in locations or circumstances in which use of the device is not allowed, dangerous, and/or possibly illegal. This is made more complex because of the mix of uses to which mobile devices are applied.
Embodiments of the invention are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings in which like reference numerals refer to similar elements.
Embodiments of the invention are generally directed to context-based limitation of mobile device function.
As used herein:
“Mobile device or system” means a mobile electronic device or system including a cellular telephone, smart phone, personal digital device, or handheld computer.
In some embodiments, a mobile device or system automatically limits some or all functionality of the mobile device or system based on the current device or system context, where the context of the device or system includes the type of usage, the physical location, and the circumstances of usage. In some embodiments, the limitation of a function of a mobile device or system may in some contexts be a prohibition or disabling of the function, and in some contexts may be an allowance of the function with certain restrictions.
In some embodiments, the current context of a mobile device or system includes one or more factors, where the factors may include a class of operation of the mobile device (such as business or personal use), whether the physical location is known, whether the current physical location is prohibited for a function, what the circumstances of use of the mobile device are (such as the use of the mobile device in a business meeting), whether the mobile device is in motion, and whether the mobile device is receiving a beacon or other signal indicting a prohibited function. The beacon may include, but is not limited to, a WiFi signal or other protocol signal.
In some embodiments, a mobile device or system determines a physical location for the device or system using a location determination technology, including, but not limited to, a GPS (global positioning satellite) receiver and circuit, a network location (for example, the detection of a local wireless network within a work environment), or other detected location data. In some embodiments, a velocity of the device may be determined by the same technology, such as by GPS technology, or by another technology.
In some embodiments, a mobile device or system may utilize the physical location of the device or system as a factor in determining circumstances of usage. For example, the mobile device may determine from the physical location that the mobile device is being used within a work environment, which may result in a first set of functions being limited or locked, or that the mobile device may determine that the mobile device is outside of the work environment, which may result in a second set of functions being limited or locked. In some embodiment, a mobile device may access other data to assist in determining circumstances, including access of the calendar of the user to determine an expected circumstance at a particular time.
In some embodiments, functionality of a mobile device or system is locked based on a table or other data format explicitly defining certain contexts in which functions are limited, such as regions in which all or particular device operations are prohibited (such as defense agencies or government facilities) and regions in which certain functions are limited. In some embodiments, a mobile device may lock as a preventative measure if the mobile device is transported to an “unexpected” location, as determined from prior usage patterns and calendar entries, because the unexpected location may indicate theft or unauthorized use. In this event, the mobile device may additionally report its location to a predetermined service or phone number to aid in its recovery.
In one example, a mobile device or system may be configured to address the increasing scrutiny applied to cell phones and PDAs with onboard cameras by prohibiting or restricting the photographic function as required. In this example, the mobile device is equipped with a disabling device or feature that operates to lock the photographic functionality of the mobile device when the mobile device is within a prohibited or restricted zone. A prohibited or restricted zone may be defined based on device location (determined by GPS or other location determining technology) or may be indicated by beaconing, in which, for example, an authorizing or prohibiting signal is broadcast over a short range wireless network. The limitation of the photographic function may allow for increased security in sensitive corporate and government environments, such as R&D facilities and courtrooms. In another example, a location may be a live performance theater or movie theater, where attendees are not authorized to record performances or shows.
In some embodiments, the limitation on functionality of a mobile device may be made tamper-resistant through well-known means of protecting the integrity of data, including, but not limited to, integrity verification of access control lists or tables.
In some embodiments, the determination of the context may include the following: The mobile device may determine a current type or class of operation of the mobile device 204, such as a business operation or a personal operation. The mobile device may determine physical location information 206, such as GPS location data, location determined by network link, or location determined by an external location beacon or other signal received by the mobile device. The mobile device may determine velocity information 208, such as velocity information determined based on GPS signals, which may, for example, be used to determine whether the mobile device is being used in a moving vehicle. The mobile device may determine the circumstances of operation of the mobile device 210, which may include use of location and velocity information, as well as information such as calendar data. Circumstances may include, but are not limited to, the use of the mobile device in a business meeting or the use of the mobile device in a moving vehicle such as an automobile. The mobile device may receive and interpret prohibition or restriction signals 212, such as signals prohibiting use of a camera or signals prohibiting audible signals (such as ringers).
In some embodiments, the mobile device determines the limitations for the requested function based at least in part on the current context of the mobile device 214. If the requested function is not allowed with the current context of the mobile device 216, the function is disabled and the request is denied 222. If the requested function is allowed but limited 218, the function is enabled with restrictions 224. If the requested function is not limited, the requested function is allowed without restriction 220.
The mobile device 400 may further include one or more memories or sets of registers 412, which may include non-volatile memory, such as flash memory, and other types of memory. The memory or registers 412 may include one more groups of settings for the device 414, including default settings, user-set settings established by user of the mobile device, and enterprise-set settings established by an enterprise, such as an employer, who is responsible for IT (information technology) support. The memory 412 may further include one or more applications 416, including applications that support or control operations to limit the functionality of the mobile device based on the context of the mobile device. The memory 412 may further include user data 418, including data that may affect limitations of functionality of the mobile device and interpretations of the circumstances of use of the mobile device. For example, the user data 418 may include calendar data that may be used by the mobile device to interpret what circumstances are expected at certain times. In a possible example, a calendar entry regarding a meeting may be used to determine that the mobile device is present in a business need and that certain functions should be limited. The memory 412 may further include a table, database, or data structure to reflect the functional limitations of the device depending on the context for the mobile device 426. An example of such a table is illustrated in
The mobile device may include various elements that are related to the functions of the system that are subject to limitation. For example, the mobile device may include a display 420 and display circuitry 421 (with certain display items being limited in certain contexts); a speaker 422 and audio circuitry 423 including audible signaling (ringers) (which may turned off or limited in volume in certain contexts); a camera 424 and camera circuitry 425 (which may be limited in certain contexts, such as shown in
In this illustration, certain functions 502 of a mobile device may be limited depending upon the various context elements. In some embodiments, certain limitations may be set by default or may be a part of a group of the settings for the mobile device. The illustrated context elements are the class of operation of the mobile device 504 (such as business or personal use); an unknown physical location 506 (such as when location determining hardware is unable to determine a physical location, which may be because, for example, a GPS signal cannot be received); certain restricted locations for the function 508; certain restricted circumstances for the function 510; limitations of the device when the device is in motion such as motion above a certain velocity 512 (when operation in a moving vehicle may be presumed); and whether the function may be limited when a specific prohibition signal is received 514. Other context elements may include time of day or date, in which certain functions may be limited at certain times or dates, and external conditions experienced by the mobile device, such as temperatures and sharp movements, which may result in limitation of certain functions.
In some embodiments, certain limitations based on the contact may be applied for certain functions. For example, a camera function 520 may be allowed only for personal operations; may be prohibited if the physical location is unknown; might be prohibited or only allowed with restrictions in certain work locations; might be allowed in motion; and prohibited if a prohibition signal is received. In another example, text messaging 522 might be prohibited in automobile driving, and may be prohibited in motion over a certain speed (because the user may be driving) unless a waiver screen is passed indicating that the user is not operating a motor vehicle (as when the user is a motor vehicle or public transportion passenger). In another example, the ringer 524 for the mobile device be disabled in certain known locations (such as a theater and a church) and may be disabled in office meeting circumstances. The table 500 may include other functions as well, shown as Function 4 through Function 7 526-534.
