1. Field of the Invention
The present invention relates to a mobile terminal that can detect a user's movement. More particularly, the present invention relates to an apparatus and a method for controlling a volume of a mobile terminal to variably control an output volume suitable for activity depending on a user's movement.
2. Description of the Related Art
Today, various types of portable terminals such as cellular phones provide various functions to meet well-being trends in addition to traditional multimedia functions, which include music reproduction, moving image reproduction, Digital Multimedia Broadcasting (DMB) viewing, etc. More particularly, as an interest in health of people grew, various mobile terminals having a health-related function are competitively brought to the market. For example, there is a terminal mounted on a human body for measuring a user's exercise amount and in turn displaying an exercise effect.
Therefore, occasionally, a user may exercise while listening to music output from a mobile terminal via an earphone connected to the mobile terminal. Of course, the user may talk with a counterpart using the earphone during an exercise. However, when the user transitions to more intense exercise, music that has been reproduced at a previously set volume may not be heard. For example, when a user walks slowly and then suddenly runs, the user cannot properly listen to the music at a previously set volume due to elevated noise level associated with the running. Therefore, the user has an inconvenience of having to stop the exercise for a momentarily and resume, or try adjust the volume during the run.
The present invention provides an apparatus and a method for controlling a volume of a mobile terminal that overcome the inconvenience stated above, by automatically controlling a volume output during an exercise.
An exemplary aspect of the present invention is to provide an apparatus and a method for controlling a volume of a mobile terminal which automatically control an output volume level with consideration of a user's motion activity.
In accordance with an aspect of the present invention, an apparatus for controlling a volume in a mobile terminal includes a motion detector for outputting motion information from a user's movement, and a controller for determining the user's activity from the motion information output from the motion detector, and determining an appropriate output volume responsive to the activity.
In accordance with another aspect of the present invention, a method for controlling a volume in a mobile terminal includes obtaining motion information from a user's movement, determining the user's activity from the obtained motion information, and determining an output volume level proportional or appropriate to the determined activity.
Other exemplary aspects, advantages and salient features of the invention will become apparent to a person of ordinary skill in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses exemplary embodiments of the invention in more detail.
The above features and advantages of certain exemplary embodiments of the present invention will be more apparent to a person of ordinary skill in the art from the following detailed description taken in conjunction with the accompanying drawings, in which:
Throughout the drawings, like reference numerals will be understood to refer to like parts, components and structures.
The following description, with reference to the accompanying drawings, is provided to assist a person of ordinary skill in the art with a comprehensive understanding of exemplary embodiments of the invention. The description includes various specific details to assist in that understanding but these details are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the exemplary embodiments described herein can be made without departing from the spirit of the invention and the scope of the appended claims. Also, descriptions of well-known functions and constructions may be omitted for clarity and simplicity so as not to obscure appreciation of the present invention by a person of ordinary skill with such well-known functions and constructions.
The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purposes only and not for the purpose of limiting the invention as defined by the appended claims.
It is to be understood that the singular forms “a”, “an”, and “the” include plural references unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” typically includes reference to one or more of such surfaces.
By the term “substantially” typically means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those skilled in the art, and may occur in amounts that do not preclude the effect the characteristic was intended to provide.
Preferred exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. Exemplary embodiments of the present invention provide an earphone device outputting sound in accordance with audio signals received from terminals. In particular, the present invention provides an apparatus and method for an earphone device that controls a terminal communicating with the earphone device according to the use or non-use of the earphone device.
Exemplary embodiments of the present invention provide a mobile terminal that can detect a user's motion, and more particularly, a technique for variably controlling an output volume suitable for a specific activity of a user's motion. The activity denotes motion strength (activity). That is, according to an exemplary embodiment of the present invention, a volume can be selectively controlled in proportion to a motion's strength. Generally, when a numerical value of a user's movement velocity, heartbeat, etc. is increased, it may be determined that the user's activity has been elevated.
Referring now to
In addition, the mobile terminal 10 may receive the motion information from at least one external unit mounted on the user's body portion. Referring to
As shown, the mobile terminal 10 may receive the motion information from at least one external unit mounted on the user's body portion and/or from a detecting unit of the mobile terminal 10. Here, the GPS satellites may be classified into external units not mounted on the user's body portion. At this point, the mobile terminal 10 may obtain the motion information by communicating with the external unit via a wired line or wirelessly.
After receiving the motion information from the detecting unit and/or the external unit, the mobile terminal 10 considers all received information to determine the user's activity. That is, the mobile terminal 10 may determine the level of a user's activity by comparing stored reference values of a database. After that, the mobile terminal 10 controls a volume to an output volume corresponding to the determined size of the user's activity. An appropriate sound level is selectively controlled to correspond with the level of detected activity via an earphone in communication with the mobile terminal 10. In addition, the newly adjusted sound level may also be reproduced via a wireless ear set that can perform wireless communication, such as Bluetooth. For example, when a current heartbeat and movement velocity becomes higher than before, the mobile terminal 10 in turn increases an output volume by a predetermined amount. The activity may be subdivided into various steps depending on motion information such as the heartbeat, movement velocity, etc., and these subdivided activities may match with motion states such as ‘walk’, ‘run’, ‘jump’, etc. As a faster movement is detected, the level of sound output can be increased depending on these motion states.
Referring now to
In operation, the controller 111 controls an overall operation of the mobile terminal 10, and determines a user's motion state to control an output volume.
The input unit 112 performs a relevant function on the controller 111, and more particularly, outputs an input signal for performing a volume control.
The display unit 113 displays an operation of a relevant function under control of the controller 111.
The storage unit 114 stores parameters for controlling the mobile terminal 10 and various information under control of the controller 111. More particularly, the storage unit 114 stores suitable volume values designated in advance according to degree of a user' activity. After determining the user's activity, the controller 111 controls an output volume corresponding to the activity with reference to the volume values stored in advance in the storage unit 113. However, since suitable volume values depending on a user's activity may differ for each user, it can be updatable by a user. In this case, the controller 111 may control an interface for updating a suitable volume value corresponding to a relevant activity.
As described with reference to
The voice processor 116 receives a signal of a relevant output volume under control of the controller 111 and outputs the same to a relevant speaker.
The motion detector 117 detects motion information required for the controller 111 to determine a user's activity. As described above, the motion detector 117 may include a detecting unit such as an acceleration sensor for detecting a movement velocity, a GPS receiver, etc. In addition, the motion detector 117 may receive the motion information from an external unit mounted on the user's body portion, and provide the received motion information to the controller 111. The external unit may be a unit for measuring heartbeat, a unit for measuring a movement velocity that is known to those skilled in this art, etc.
Referring now to
The controller 111 determines the user's activity by applying the received motion information to a relevant algorithm in step 302. As described above, the activity may be subdivided into a plurality of steps.
The controller 111 determines an output volume by determining a volume value corresponding to the determined activity based on a database of the storage unit 113 in step 303.
Having thus described a preferred embodiment of adjusting the output volume of a mobile terminal during various stages of a user's activity, it should be apparent to those skilled in the art that the teachings of the present invention resolve inconvenience of being interrupted during an activity or exercise.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
