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

The mobile communication device (10) adjusts the distance between the surface of the device and one or more other objects (22a, 22b, 24) that may come into contact with the device (10) (e.g., receipts, credit cards, keys, money, user's hand or fingers, etc.) friction level between them. To adjust friction, the device (10) first determines its current environmental context, eg whether it is in the user's pocket (20) or resting on a table surface. Then, based on this context, the device (10) changes the coefficient of friction to increase or decrease the friction between the surface of the device (10) and the surfaces of other objects (22a, 22b, 24). Changing the friction allows the user to grip the device (10) more easily and / or reduces the chance of other objects (22a, 22b, 24) in contact with the device (10) being inadvertently removed from the storage location along 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...
