## Background
TECHNICAL FIELD OF THE INVENTION
This invention relates generally to mobile computing devices, and more particularly to a method of informing a user about received calls or messages through haptic signals.
BACKGROUND OF THE INVENTION
Cell phones, particularly smart phones, are becoming more ubiquitous and versatile. As demand grew, cell phones design also grew to support more functionality including telephone calls, emails, text messages, web browsing, Instant Messaging, social networking, and scheduling. When any of these functions receives a communication (for example, a call or an email), the cell phone notifies the user through a visual or audio signal. The user may then check the cell phone's display to view information about the received communication (for example, the source or urgency of the communication).
However, it may not always be convenient for the user to check his phone when the communication is received. For example, the user may be in a meeting, where it is hard to watch a display or to listen to a voice feature. Furthermore, the user may have to navigate through several windows and menus before ever seeing the information about the received communication.
SUMMARY OF THE INVENTION
According to one embodiment, a mobile communication device is provided that includes a receiver, a ringer, and a signal generator. The receiver may be configured to receive a swipe indicating a user query for the source of a received call or message. The ringer may be configured to produce an audible signal when the computing device receives a call or message. The mobile communication device may be operable to silence the ringer. The signal generator may be configured to generate a vibration with a first intensity corresponding to a first classification of the source of the call or message and with a second intensity corresponding to a second classification of the source of the received call or message.
According to another embodiment, a method for informing a user through haptic signals may begin by receiving, at a mobile computing device, a user query for information regarding a received call or message. The user query may include some physical act performed on the mobile computing device. The method further includes generating, by the mobile computing device, a haptic signal to indicate a response to the user query for the information regarding the call or message.
According to yet another embodiment, a computing device is provided that includes a receiver and a signal generator. The receiver may be configured to receive a user query for information regarding a received call or message. The user query may include a physical act performed on the computing device. The signal generator may be configured to generate a haptic signal indicating a response to the user query for the information regarding the call or message.
Technical advantages of certain embodiments of the present disclosure include providing a user a way to check for information about received calls or messages without disturbing others. Specifically, only the user may perceive the haptic signal generated in response to his query for information. Other technical advantages will be readily apparent to one skilled in the art from the following figures, descriptions, and claims. Moreover, while specific advantages have been enumerated above, various embodiments may include all, some or none of the enumerated advantages.

In particular embodiments, display 110 may be a touchscreen configured to receive user input through tactile touch. As an example, and not by way of limitation, a user may select an item displayed on display 110 by touching display 110 relative to the location of the displayed item. As another example, and not by way of limitation, the user may scroll up or down by swiping up or down on display 110. In some embodiments, display 110 may be configured to generate a haptic signal to the user. As an example and not by way of limitation, display 110 may be configured, according to well-known techniques, to present a texture to a user. For example, display 110 may be configured to feel rough and grainy like sandpaper when the user touches display 110. Although this disclosure describes display 110 performing various functions, this disclosure contemplates display 110 performing any suitable functions.
Computing device 100 may include a trackball 120. In particular embodiments, trackball 120 may be configured to navigate selections on display 110. In some embodiments, a user of computing device 100 may use trackball 120 to make selections displayed on display 110. Computing device 100 may further include a plurality of buttons 130. In particular embodiments, buttons 130 may be pressed by a user of computing device 100 to perform various functions. As an example, and not by way of limitation, buttons 130 may be pressed to power on and power off computing device 100. As another example, and not by way of limitation, buttons 130 may be pressed to initiate or to end telephone calls. In particular embodiments, buttons 130 may be located on the side of computing device 100. Computing device 100 may further include a keyboard 140 configured to enter user input. In particular embodiments, keyboard 140 may include a plurality of buttons 130. In some embodiments, buttons 130 on keyboard 140 may include alphanumeric characters.
Computing device 100 may be configured to receive calls or messages 150. In particular embodiments, calls or messages 150 may be sent to computing device 100 wirelessly. In some embodiments, call or message 150 may be a telephone call, an email message, a text message, an SMS message, or any other suitable call or message received at computing device 100. In some embodiments, computing device 100 may be configured to generate a visible or audible signal to indicate a call or message 150 is received. As an example and not by way of limitation, computing device 100 may include a ringer that produces a ringing noise or a light that flashes when a call or message 150 is received.
