DESCRIPTION OF THE EMBODIMENTS

Many applications may utilize information relating to the orientation of the computing device on which they are operating. As used herein, the term “orientation” is used to refer to an angular bearing of a computing device relative to the environment. For example, the orientation of a computing device may have an azimuthal component and an elevation angle component. Applications may use such orientation information to adapt the manner in which they are functioning. For example, the orientation of the computing device can be used in conjunction with the geographical position of the computing device to identify a feature in the user's environment that the computing device is pointed toward. In the case of an augmented reality application, the orientation of the computing device may correspond with the viewing direction of a camera disposed on the computing device, and the augmented reality application may adapt an image that is being displayed to the user based on the orientation of the computing device. Orientation information can also be used by an application to determine whether the computing device is resting on a level surface or is being held by a user, for example, and the application may adjust its output accordingly. Various additional uses for such orientation information will be recognized in light of the present description.

Traditionally, computing devices are equipped to identify a single orientation. However, many computing devices have members that are capable of being separately oriented in different directions. For example, computing devices such as laptops, convertible tablets, and flip-style phones, among others, include a base and a lid that are capable of pivoting and/or tilting with respect to one another. Embodiments described herein provide for the detection of the individual orientations of two or more members of a computing device.

Further, in various embodiments, applications utilize information relating to an alignment of members, e.g., a lid and a base, of a computing device with respect to each other. As used herein, the term “alignment” is used to refer to the position of one member of a computing device relative to another member of the computing device. Applications may utilize such alignment information to adapt the manner in which they are functioning. For example, a camera of a computing device may adjust its output based on the alignment of the lid of the computing device with respect to the base. In addition, the alignment of the lid of a computing device with respect to the base may be used to determine the orientation of the lid based on the orientation of the base.

In the following description and claims, the terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact. However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.

Some embodiments may be implemented in one or a combination of hardware, firmware, and software. Some embodiments may also be implemented as instructions stored on a machine-readable medium, which may be read and executed by a computing platform to perform the operations described herein. A machine-readable medium may include any mechanism for storing or transmitting information in a form readable by a machine, e.g., a computer. For example, a machine-readable medium may include read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; or electrical, optical, acoustical or other form of propagated signals, e.g., carrier waves, infrared signals, digital signals, or the interfaces that transmit and/or receive signals, among others.

An embodiment is an implementation or example. Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” “various embodiments,” or “other embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the inventions. The various appearances “an embodiment,” “one embodiment,” or “some embodiments” are not necessarily all referring to the same embodiments.

Not all components, features, structures, characteristics, etc. described and illustrated herein need be included in a particular embodiment or embodiments. If the specification states a component, feature, structure, or characteristic “may”, “might”, “can” or “could” be included, for example, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.

It is to be noted that, although some embodiments have been described in reference to particular implementations, other implementations are possible according to some embodiments. Additionally, the arrangement and/or order of circuit elements or other features illustrated in the drawings and/or described herein need not be arranged in the particular way illustrated and described.

FIG. 2 is a perspective view of a computing device 200 in accordance with embodiments. In various embodiments, the computing device 200 is the computing system 100 described above with respect to FIG. 1. Further, the computing device 200 may be any type of computing device that includes at least two members, such as a base and a hinged lid. For example, the computing device 200 may be a flip-style mobile phone or a laptop computer.

The computing device 200 shown in FIG. 2 includes a base 202, as well as a lid 204 that is pivotally attached to the base 202. The base 202 of the computing device 200 may include a keyboard 206 and a touchpad 208. The base 202 may also include a first orientation sensor 210. The first orientation sensor 210 may include, for example,a magnetometer, an accelerometer, a gyroscope, and the like. In addition, the first orientation sensor 210 may include a variety of different types of sensors. Further, the first orientation sensor 210 may be located anywhere within the base 202 of the computing device 200.

The lid 204 of the computing device 200 may include a display screen 212 and a camera 214, such as a Webcam. The lid 204 may also include a second orientation sensor 216. The second orientation sensor 216 may include, for example, a magnetometer, an accelerometer, a gyroscope, and the like. In addition, the second orientation sensor 216 may include a variety of different types of orientation sensors. Further, the second orientation sensor 216 may be located anywhere within the lid 204 of the computing device 200.

Each of the orientation sensors 210 and 216 separately detect the orientation of the member to which it is coupled. For example, the first orientation sensor 210 may be used to detect the orientation of the base 202 of the computing device 200, while the second orientation sensor 216 may be used to detect the orientation of the lid 204 of the computing device 200. In various embodiments, the first orientation sensor 210 and the second orientation sensor 216 may be used to detect the orientations of the base 202 and the lid 204, respectively, at the same point in time or at different points in time, depending on the specific application. The sensor information may be sent to the orientation reporter 130 for further processing, as described below with reference to FIG. 3.

FIG. 3 is a process flow diagram showing a method 300 for detecting an orientation of a lid and a base of a computing device in accordance with embodiments. The computing device that implements the method 300 may be the computing device 200 discussed with respect to FIG. 2.The method begins at block 302, at which the orientation of the lid of the computing device is detected by the orientation reporter using a first orientation sensor. The orientation of the lid may include an orientation of the lid with respect to the environment of the computing device.

At block 304, an orientation of a base of the computing device is detected by the orientation reporter using a second orientation sensor. The orientation of the base may include an orientation of the base with respect to the environment of the computing device.

At block 306,the orientation reporter generates an orientation indicator based on the orientation of the lid and the orientation of the base. In some embodiments, the orientation indicator is a combined orientation indicator that simultaneously indicates both the orientation of the base and the orientation of the lid. In some embodiments, the orientation indicator indicates a specified orientation, which may be either the orientation of the base only or the orientation of the lid only. Reporting the orientation of the lid only or the base only enables the orientation reporter to provide backward compatibility for applications that may not be configured to properly interpret a combined orientation indicator. The computing device may include a user interface that enables a user to select the type of orientation indicator desired. In embodiments, the user interface is a switch, such as a user-level software switch or a hardware switch, that includes both a lid setting and a base setting. When the switch is on the lid setting, the orientation indicator reports the orientation of the lid. When the switch is on the base setting, the orientation indicator reports the orientation of the base.

At block 308, the orientation reporter sends the orientation indicator to an application executing on the computing device. In some embodiments, the application is an orientation-based application or a context-aware application. The application may utilize the orientation indicator to determine a number of conditions relating to the environment of the computing device. The application may then adapt its behavior, e.g., its output, accordingly. For example, if the application is an augmented reality application, the application may use the orientation of the lid, as specified by the orientation indicator, to determine the orientation of the camera, as well as the objects at which the camera is pointing. This may enable the application to provide the user with a dynamic and interactive augmented reality experience.

As another example, the application may determine the orientation of the computing device relative to a working surface based on the orientation of the base, as specified by the orientation indicator. This may enable the application to determine, for example, whether the base of the computing device is resting on a level surface or is being held by a user. The application may then make a number of determinations based on this information, such as whether the user is likely to stop using the computing device soon. The application may then adjust its output accordingly. For example, if the application determines that the user is likely to stop using the computing device and, thus, the application soon, the application may begin to display more popular or highly-rated information to the user in order to catch the user's attention and to delay the closing of the application.

In addition, the alignment sensor 416 may be used to determine an alignment of the lid 404 relative to the base 402. The orientation of the base 402 and the alignment of the lid 404 relative to the base 402 may then be used to determine the orientation of the lid 404. Further, in some embodiments, the orientation sensor 410 may be located within the lid 404 of the computing device 400, rather than the base 402. In such an embodiment, the orientation of the lid 404 and the alignment of the lid 404 relative to the base 402 may be used to determine the orientation of the base 402. The sensor information may be sent to the orientation reporter 130 for further processing, as described below with reference to FIG. 5.

At block 508, the orientation reporter generates an orientation indicator based, at least in part, on the orientation of the second member. In some embodiments, the orientation indicator may be generated based on the orientation of the second member and the orientation of the first member. The orientation indicator may be a combined orientation indicator, or may indicate an orientation of a selected one of the members, as discussed above with respect to FIG. 3.

At block 510, the orientation reporter sends the orientation indicator to an application executing on the computing device. In some embodiments, the application is an orientation-based application or a context-aware application.

It will be appreciated that any number of additional actions may be included within the method 500, depending on the specific application. For example, the method 500 may be used to detect and report the orientation of any number of additional components of the computing device, such as a mouse, numeric keypad, or keyboard, among others. Such additional components may be communicably coupled to the computing device via a wired or wireless connection. Further, the method 500 may be used to detect and report the orientation of specific objects within the environment of the computing device, e.g., a user's head, with respect to the computing device.

The method further includes generating an orientation indicator based, at least in part, on the orientation of the second member, and sending the orientation indicator to an application executing on the computing device.

The first member may be a base of the computing device, and the second member may be a lid of the computing device. Alternatively, the first member may be a lid of the computing device, and the second member may be a base of the computing device.

In addition, generating the orientation indicator based, at least in part, on the orientation of the second member may include generating the orientation indicator based on the orientation of the second member and the orientation of the first member.

EXAMPLE 4

At least one machine readable medium having instructions stored therein is described herein. In response to being executed on a computing device, the instructions cause the computing device to detect an orientation of a base of the computing device and an orientation of a lid of the computing device relative to an environment of the computing device. The instructions also cause the computing device to generate an orientation indicator based on the orientation of the base and the orientation of the lid and send the orientation indicator to an application executing on the computing device. The number of instructions may include an orientation application programming interface (API).

Detecting the orientation of the base and the orientation of the lid relative to the environment may include collecting orientation information from one or more orientation sensors disposed within the computing device. In addition, detecting the orientation of the base and the orientation of the lid relative to the environment may include calculating an orientation of the computing device relative to a working surface.

It is to be understood that specifics in the aforementioned examples may be used anywhere in one or more embodiments. For instance, all optional features of the computing device described above may also be implemented with respect to either of the methods or the computer-readable medium described herein. Furthermore, although flow diagrams and/or state diagrams may have been used herein to describe embodiments, the inventions are not limited to those diagrams or to corresponding descriptions herein. For example, flow need not move through each illustrated box or state or in exactly the same order as illustrated and described herein.

The inventions are not restricted to the particular details listed herein. Indeed, those skilled in the art having the benefit of this disclosure will appreciate that many other variations from the foregoing description and drawings may be made within the scope of the present inventions. Accordingly, it is the following claims including any amendments thereto that define the scope of the inventions. claims
