摘要:
The method, terminal and computer program product of the present invention are capable of adjusting the power consumption of short-range communication transceivers, such as RFID, IR transceivers or the like. Energy management of the transceiver is achieved by limiting activation of the transceiver to periods of user-interface illumination. The transceiver, therefore, uses less power because it is only activated by an intentional gesture by the user, i.e., a gesture that will initiate the illumination of a user-interface. In addition, the user of terminal is aware, via observation of the illumination, that the terminal is in an active transceiver reading state and, thus, the invention provides for a safe environment in which inadvertent reading of tags or data communication is lessened.
摘要:
The method, terminal and computer program product determine the acceleration of a mobile terminal associated with the short-range communication transceiver and adjusts the power consumption of the short-range communication transceiver based upon whether a predefined acceleration threshold has been exceeded. To adjust the power consumption, the frequency at which the transceiver is activated may be altered. Thus, the power consumption of the transceiver may be reduced when the acceleration threshold is exceeded and/or may be increased when the acceleration threshold is not exceeded. Due to the adjustment of power consumption by transceivers, power is conserved in the mobile terminals associated with transceivers, which permits the mobile terminals and the transceivers to operate longer without requiring charging or replacement of the power supply.

A computer-implemented method is described for displaying an on-screen keyboard on a touch-sensitive display of an electronic device is described. The method may detect contact of a finger in a contact area of the display and monitor movement of the contact area on display in response to movement of the finger across the display. The method may determine that the contact area is proximate a region of the display that includes a key of the on-screen keyboard, and provide a haptic effect to indicate that the finger is proximate the at least one key. The haptic effect may be provided via the display and be provided proximate to the detected contact area. In an example embodiment, an anchor on one or more keys of the on-screen keyboard is provides a further haptic effect to the finger when the finger is proximate to the anchor.

Embodiments of tactile stimulation apparatuses and components of such apparatuses are generally described herein. For example, in one embodiment, a tactile stimulation apparatus is provided. This tactile stimulation apparatus has a composite section comprising an insulation region and a semiconducting region that is proximate to the insulation region. This insulation region is touchable by a body member. Additionally included is a voltage source proximate to the semiconducting region. Here, the voltage source is configured to charge the semiconducting region to an electric potential, which produces an electrosensory sensation on the body member.

摘要:
An apparatus for producing an electrosensory sensation to a body member (120). The apparatus comprises one or more conducting electrodes (106), each of which is provided with an insulator (108). When the body member (120) is proximate to the conducting electrode, the insulator prevents flow of direct current from the conducting electrode to the body member. A capacitive coupling over the insulator (108) is formed between the conducting electrode (106) and the body member (120). The conducting electrodes are driven by an electrical input which comprises a low-frequency component (114) in a frequency range between 10 Hz and 500 Hz. The capacitive coupling and electrical input are dimensioned to produce an electrosensory sensation. The apparatus is capable of producing the electrosensory sensation independently of any mechanical vibration of the one or more conducting electrodes (106) or insulators (108).
摘要:
An apparatus for presenting a time-variant information element in a vehicle, which has a steering wheel (1602), comprises one or more remotely and individually controllable tactile pads (1620), which produce a tactile sensation in response to a respective pad output signal, which is produced by a controller (CTRL). The tactile pads are positioned or adapted to be positioned on the steering wheel (1602) or proximate to it, such that they can be touched by at least one hand (1610,1612) of the vehicle driver while driving the vehicle. The apparatus further comprises means for determining the time-variant information element to be presented and for applying the determined time-variant information element to the controller and means for encoding the determined time-variant information element by the controller into temporal variations of the one or more pad output signals.
