Embodiment Construction

[0027] In general, the term "haptic" refers to the science of tactile feedback, ie, nonverbal communication involving touch. For example, when a user's mobile device receives an incoming call or text message, the device may vibrate. Typically, vibration is achieved by controlling an inertial actuator within the device to vibrate the entire device. Vibration is used to alert the user of an incoming communication or some other event. However, while such feedback is useful, there is another type of haptic technology that is also becoming popular. This technology is called "high-definition haptics."

[0028] High-definition haptics allow users to perceive a greater variety of spatially or temporally separated effects, which can then be used to enhance the granularity of the effects produced. For example, rather than controlling a single inertial actuator within a device to cause the entire device to vibrate as a whole, specifically selected portions of the device can be control...

Abstract

A mobile communication device (10) adjusts a level of friction between a surface of the device and one or more other objects (22a, 22b, 24) that may be in contact with the device (10), such as receipts, credit cards, keys, money, the user's hand or fingers, and the like. To adjust the friction, the device (10) first determines its current environmental context, such as whether it is inside the user's pocket (20) or lying on a table surface, for example. Then, based on that context, the device (10) varies a coefficient of friction to increase or decrease the friction between the surface of the device (10) and the surfaces of the other objects (22a, 22b, 24). Varying the friction allows a user to grip the device (10) easier and / or reduce the chance that the other objects (22a, 22b, 24) in contact with the device (10) are also inadvertently removed from the storage location with the device.

Description

technical field [0001] The present disclosure relates to a mobile communication device configured to vary the friction between its surface and the surface of another object in contact with the mobile communication device and methods thereof. Background technique [0002] Mobile communication devices, such as cellular telephones, are popular and ubiquitous. Their popularity among users is not only due to the variety of functions they offer, but also because of their size. In particular, such devices are sized to allow a user to grip them comfortably and place the device in a storage location such as a pocket, handbag or the like when not in use. This allows users of these devices to always keep their devices close at hand. [0003] However, manufacturers continue to reduce the size of their devices. As devices get smaller, their surfaces get smoother. Furthermore, some of the locations where a user may place a device, such as in a pocket or purse, are relatively small com...
