Definitions

  • the present invention is related generally to wireless communication devices and connectable external accessories and, more particularly, to a system and method of displaying visual cues on the display of a wireless communication device.
  • Modern wireless communication devices such as cellular telephones, produce a variety of audible signals.
  • a cellular telephone produces the voice of the caller at its earpiece.
  • the cellular telephone additionally produces audible signals to provide the user with feedback or with cellular telephone status information.
  • the cellular telephone produces a ringer sound to alert the user of an incoming cellular telephone call, or produces a key "beep" when a key is depressed.
  • the cellular telephone may also produce a message alert signal when voicemail is received.
  • the cellular telephone will have separate user programmable volume levels for each of the audible signals it produces.
  • Modern cellular telephones are also designed so that the user may connect external accessories to the cellular telephone, enabling the user to use the cellular telephone in a wider range of applications than if the cellular telephone were used by itself.
  • a headset accessory may be connected to some cellular telephones so that a microphone and earpiece are positioned in proximity of the user's mouth and ear, respectively, to permit hands-free operation of the cellular telephone.
  • Another example of a common external accessory connectable to a cellular telephone is a carkit accessory that allows the cellular telephone to be used while driving an automobile without the inconvenience of holding the cellular telephone.
  • the kit includes a microphone that can be attached to a convenient location within the automobile so the user does not have to hold the cellular telephone, and the kit is connected to the automobile's audio system so that the audible signals produced by the cellular telephone can be heard over the speakers of the audio system.
  • a cellular telephone has separate user programmable volume levels for the earpiece, ringer, key beeps, and message alert.
  • a set of separate volume levels is stored for each of the external accessories that may be connected to the cellular telephone, in addition to the volume levels for the cellular telephone itself.
  • the user can program one set of volume levels when a headset is connected to the cellular telephone, a second set of volume levels when a carkit is connected to the cellular telephone, and a third set of volume levels when the cellular telephone is being used without any external accessory.
  • the user does not need to reprogram the volume levels each time the cellular telephone is used with a different external accessory or without any accessory at all.
  • the present invention is embodied in a system and method directed to showing on a display of a wireless communication device a label indicating which volume level of the wireless communication device or a connected external accessory is being programmed.
  • the wireless communication device includes a processor, an output device, and a display.
  • the wireless communication device can be connected to an external accessory through a connector.
  • the processor receives identification data that indicates whether the wireless communication device is connected to an external accessory and further identifies the type of external device.
  • the processor generates selection data based on the identification data.
  • the display will show a label related to the user programmable volume level being programmed based on the selection data generated by the processor.
  • the wireless communication device further includes an output driver that receives the selection data from the processor and generates driving signals at the programmed volume levels in response to the selection data.
  • the resulting driving signals are used to drive the output device of the wireless communication device or the external accessory, depending on whether the wireless communication device is connected to an external accessory, as reflected by the selection data.
  • the wireless communication device also includes storage locations for storing the user programmable volume levels.
  • the particular storage location where the programmable volume levels are stored is selected based on the selection data generated by the processor.
  • FIG. 1 is a functional block diagram of an exemplary embodiment of the wireless communication system of the present intention.
  • FIG. 2 illustrates the connection of different external accessories to the system of FIG. 1.
  • FIG. 3A-3D illustrate data shown on a display of the system of FIG. 1 when coupled to various external accessories.
  • a typical cellular telephone may include multiple programmable volume levels with a separate storage location for each volume level.
  • the volume menu title appearing on the cellular telephone display when programming the different sets of volume levels remains the same, regardless of whether the volume level being programmed is for the accessory or for the cellular telephone itself. For example, if the cellular telephone is connected to a headset accessory and the user programs one or more volume levels, changes will be made to the set of volume levels related to the headset by virtue of the headset being connected to the cellular telephone. In spite of the fact that the headset volume settings are being programmed, the volume menu title appearing on the cellular telephone display is the same as the volume menu title displayed when programming the volume levels of the cellular telephone itself.
  • the user cannot be certain which set of volume levels is being programmed without first ascertaining if the external accessory is truly connected to the cellular telephone. If the cellular telephone is used in a car, the user must typically manually determine whether the carkit accessory is actually connected to the cellular telephone before adjusting the volume levels. Such manual operation creates a distraction for the driver that increases the potential of being involved in a traffic accident. In another situation, the user may not notice that the cellular telephone is disconnected from the external accessory and program new volume levels for the cellular telephone itself when intending to adjust the volume settings related to the external accessory. The user may not discover that the incorrect volume levels have been adjusted until later when the user may be put into an embarrassing situation if the cellular telephone rings or produces a message alert too loudly.
  • the present invention overcomes these problems by altering the displayed volume menu title based on the particular external accessory and whether or not the cellular telephone is connected to the external accessory.
  • the principles of the present invention are applicable to a variety of wireless communication devices including, but not limited to, cellular/PCS, radio telephone, conventional radio, and the like. Accordingly, the present invention is not limited by the specific form of wireless communication device.
  • menu titles other than volume menu titles may be altered in accordance with the principles of the present invention.

Abstract

L'invention concerne un dispositif de communication sans fil (100) comprenant un dispositif de sortie audio (122), un processeur (114) et un écran (126). Ce processeur reçoit des données d'identification indiquant si un dispositif de communication sans fil est (100) connecté à un accessoire externe ou déconnecté d'un accessoire externe (201) et identifie cet accessoire externe. Le processeur (114) génère des données de sélection en fonction des données d'identification. Lorsque les niveaux sonores de programmation utilisateur ou d'autres paramètres sont en cours de programmation, l'écran (126) affiche un titre de menu indiquant si les niveaux sonores du dispositif de communication sans fil (100) ou si un accessoire externe connecté (201) est en cours de programmation. Le titre particulier est choisi sur la base des données de sélection puis affiché sur l'écran du dispositif de communication sans fil. Les données de sélection générées par le processeur peuvent également servir à choisir un emplacement de stockage où les niveaux sonores programmables sont destinés à être stockés. Le niveau sonore auquel un circuit de commande de sortie va générer des signaux de commande destinés au dispositif de sortie approprié, c'est-à-dire, soit le dispositif de communication sans fil, soit un accessoire externe connecté, est déterminé par les niveaux sonores stockés dans l'emplacement de stockage choisi sur la base des données de sélection.
