FIG. 1 illustrates a computing device that is configured to provide feedback notifications that confirm events relating to coupling or pairing amongst devices, according to one or more embodiments. The device 100 may correspond to a computing device, such as a multifunctional cellular telephony/messaging device (e.g. smart phone), or a portable computing device such as a notebook or tablet. Embodiments described herein may be implemented on various computing device types and form factors.
With reference to FIG. 1, device 100 includes a pairing system 110, an inductive signal interface 120, a communication application 130, and a library of user applications 140 (e.g. e-mail, phone application, games etc.). The inductive signal interface may utilize one or more coils 122 in order to inductively transmit and/or receive power and/or data. The communication application 130 may interface and/or control and wireless communication port 132. The pairing system 110 may include logic and functionality for enabling device 100 to communicate with other devices. In particular, the pairing system 110 may include logic and functionality that enables device 100 to communicate with other devices in a manner that is automatic, or substantially automatically programmatically implemented. For example, the pairing system 110 may operate to inductively linked computing device 100 with another device that has a compatible inductive signal interface, automatically upon the two devices being brought into operational proximity to one another (for respective coils).
As still another variation, the pairing system 110 may operate to pair the device 100 to one or more other devices using a corresponding local wireless communication medium, such as provided by Bluetooth or Wi-Fi (e.g. Wi-Fi direct). Still further, the pairing system 110 may be configured to enable more advanced sharing functionality, such as sharing application data in response to application events, synchronization, sharing an automated use of data objects, and various other forms of data exchange. In one embodiment, the pairing system 110 uses data exchange over the inductive signal interface 120, in order to securely and automatically establish a communication link with another device using the wireless communication port (as provided by the communication application 130 and the port 132).
According to embodiments, device 100 includes a feedback notification functionality that provides a notification to the user as to the occurrence of one or more advance relating to the device being paired with another device. In one embodiment, the feedback notification functionality is provided by one or more monitoring processes 112 that monitor for parameters and other information about a specific event relating to the device 100 being paired or otherwise couple to another device.
In one embodiment, monitoring process 112 monitors the inductive signal interface 120 for information and parameters relating to the device being inductively couple to another device. The monitoring process 112 may detect occurrences such as the following: (i) inductive signal being received (power or data), (ii) inductive data being transferred in, (iii) data transfer through inductive medium being completed, (iv) inductive coupling encountering a disruption or problem, and/or (v) inductive coupling being performed less than optimally. In one embodiment, the monitoring process detects when inductive data is received through the inductive signal interface 120. The monitoring process may also detect when the coil 122 of the device 100 is properly aligned with the quarrel of the other device in order to transfer power and/or data amongst the two devices. Numerous variations to examples provided may be included with embodiments provided described.
As an addition or alternative, the monitoring process 112 may detect an event relating to or stemming from the device 100 being inductively couple to another device. For example, as described in U.S. patent application Ser. No. 12/916,388, inductive coupling may be used to exchange credential information between the device 100 and another paired device, which in turn is used to establish a secure communication link with other devices over an RF medium. Thus, the inductive pairing may be followed by one or more events that result in communication between the device 100 and another pair device over an RF communication medium. As an alternative or variation, monitoring process 112 may detect occurrence of subsequent events following inductive coupling. For example, the monitoring process 112 may detect completion of the pairing process (e.g. exchange of credential information over an inductive link, followed by establishment of an RF link), as well as use of an RF link. For example, the device 100 can send or receive data over an RF link established through inductive transfer of data.
The monitoring process may similarly monitor use of application data, such as provided by her to applications 140 resident on the device 100. For example, as a result of the pairing process described (e.g. where an RF link is established through inductive exchange of information), the application 140 may transmit or receive a data object (e.g. URL). The transmission or reception of such a data object may be detected as an event by process 112.
Methodology
FIG. 2 illustrates a method for providing a feedback notification that confirms the occurrence of an event relating to data sharing or pairing amongst devices, according to one or more embodiments. A method of FIG. 2 may be implemented using components such as described by an embodiment of FIG. 1. Accordingly, reference may be made to elements of FIG. 1 for purpose of illustrating suitable components for performing a step or sub step being described.
An embodiment, a device shares information or otherwise pairs with another device (210). Data sharing may be performed amongst devices as a one-time or ad-hoc basis. Alternatively, data pairing operations may be correspond to the device 100 establishing, or participating in a persistent or long-term relationship with another device (e.g. one that lasts for multiple communication sessions). For example, as described with some embodiments, devices may generate link keys to communicate with one another over a local wireless communication medium, and the generation of the link keys may be based on credential information that is exchanged inductively. In such implementations, devices may use link keys to connect and reconnect repeatedly to a specific device.
In one embodiment, the data sharing or paring follows an inductive transfer of data (212), such as the exchange of credential information. In another embodiment, data sharing or paring establishment of an RF connection with another device, or exchange of data with another device over an RF communication medium (214).
As part of data sharing or paring, the device 100 may implement processes for monitoring events related to the data sharing or pairing (22). In some embodiments, the event(s) that is monitored is inductive (222). For example, in one embodiment, the event that is monitored corresponds to that device receiving data indicating a proper inductive link with another device. Conditions for determining that the inductive link is proper may correspond to the coil 122 of the inductive signal interface 120 being aligned or placed over or next to the coil of another device.
As an addition or alternative, the monitored event corresponds to a data transfer event that follows determination the two devices are linked or otherwise paired (224). For example, the monitored event may correspond to the device 100 successfully transferring (or receiving) application data or objects to another device following a sequence where the two devices are inductively coupled, then paired across a local wireless communication medium.
Other events may alternatively be detected that relate to the data sharing or pairing event. For example, the event may correspond to a type of communication exchanged between the two devices (e.g. secure versus unsecure) or a type of data.
Embodiments provide that feedback notification is provided following the detected event (230). The feedback notifications may be provided visually (232), such as by graphics or illumination (See e.g. FIG. 3A, FIG. 3B and FIG. 4). Alternatively, the feedback notifications may be provided audibly (234), or still further, through motion such as vibration. The feedback notifications may confirm the occurrence of an event that is expected as a result of the device sharing or pairing with another device.
For example, if device 100 inductively couples to another device to inductively exchange information, the successful positioning of the coils of the respective inductive signal interfaces may result in a confirmation feedback notification being presented to the user. Still further, the confirmation feedback notification may be timed to coincide with the actual transfer, or even completion of information through the inductive communication medium. As another variation, the confirmation feedback notification may be timed to coincide with the establishment of a local wireless communication link with a paired device, which may follow the use of the inductive link. Numerous other variations are possible. For example, the confirmation feedback notification may be generated to signify the establishment of a new pairing with another device, for use in ongoing or persistent communications across multiple communication sessions.
Usage Examples
FIG. 3A and FIG. 3B illustrate an example of a confirmation feedback notification, generated in accordance with one or more embodiments. In an embodiment, the confirmation feedback notification is visual and dynamic. More specifically, the confirmation feedback notification emulates a wave or ripple, in that it propagates across a display screen. For example, FIG. 3A illustrates the wave 310 being initiated on a display screen 320 at a start time. FIG. 3B illustrates the same wave 310 propagating across a display screen 320 and a different time. Among other benefits such a feedback notification can be timed to last for more than the duration of the event that is monitored for completion. Thus, for example, if the computing device 100 is configured to generate the confirmation feedback notification in response to an inductive pairing being initiated, the presence of the wave 310 propagating ensures that they inductive pairing will be complete before the notification is terminated. Thus, the user can receive confirmation that the inductive pairing was initiated (e.g. devices are properly place against one other), as well as confirmation that the inductive pairing was complete, using a visual feature that is dynamic and inherent to the perception of time passage.
FIG. 4 illustrates a usage example for an embodiment, in which two devices are inductively coupled. In the example provided, a mobile device 410 is inductively coupled to a tablet device 420. Each device may include an inductive signal interface positioned to receive the inductive signal interface of another device. The mobile device 410 may position is inductive signal interface on a rear façade. The tablet 420 may position its inductive signal interface on a promoter region of his front façade. To effectuate an inductive coupling, the user must bring the two devices in close proximity to or in contact with another, so that the coils of each of the respective inductive signal interfaces are aligned to make contact.
Embodiments recognize that while inductive coupling provides an easy and secure transmission medium, its connector-less nature can be offsetting to some users. A user cannot rely on physical structures such as connectors in order to decipher that a connection is made. Additionally, inductive coupling can sometimes require the alignment of coils in order for the inductive coupling to take place. The coil position, as mentioned, can sometimes be occluded to the user, resulting in the user misaligned the coils.
With such consideration in mind, embodiment provide a confirmation notification feature that is indicative of the coils for the two devices being properly aligned. Absent such confirmation notification, for example, the user may second-guess his positioning of the mobile device 410 against the tablet 420. Furthermore, the user may have little awareness the data is being transferred, absent some sensory feedback.
In FIG. 4, the confirmation notification feature is provided as a halo 430, which can be dynamic. As an alternative or variation, the confirmation notification may be provided as a wave or a ripple.
In the example provided, only one device need show the confirmation feedback notification 430. This device may be selected to be the one receiving the data, or the device that is of a particular class or type (e.g. tablet). In variations, both devices may display the confirmation notification.
