## Background
This application claims the benefit of Korean Patent Application No. 10-2005-0064299, filed on Jul. 15, 2005, which is hereby incorporated by reference as if fully set forth herein.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mobile terminal, and more particularly to a mobile terminal equipped with an event notification function.
2. Discussion of the Related Art
Conventional mobile terminals are typically designed to notify a user when a predetermined event has occurred, such as when the user has missed an incoming call, or has received a message. Typically, the conventional mobile terminals will notify a user of the event by outputting a sound or vibrating.
When a user of a conventional mobile terminal receives an incoming call from a base station, but does not respond within a predetermined period of time, the conventional mobile terminal determines that the user has missed an incoming call, and typically displays certain information relating to the missed call on a display of the mobile terminal (such as, for example, caller information, number of missed calls, and/or missed call content information).
When a conventional mobile terminal receives an incoming message, it typically outputs a sound or vibrates, and displays a received message indicator on the display of the mobile terminal. If the user does not check the received message, typically the conventional mobile terminal will periodically output a sound or vibrate, or display the received message indicator on the display of the mobile terminal.
However, a user of a conventional mobile terminal will be unaware that he or she has missed a call if they do not view the mobile terminal's display. Thus, if they miss an important call, they may not realize it for a long period of time.
Thus, to be aware of any missed calls, a user of a conventional mobile terminal must periodically check the display of the mobile terminal, which is an inconvenience. Further, if a user is visually impaired, they will be unable to recognize that they have missed a call.
Although a conventional mobile terminal may periodically output a sound or vibrate to indicate that it has received a message, this is not helpful if the mobile terminal outputs the sound or vibrates when the user is not in the vicinity of the mobile terminal.
SUMMARY OF THE INVENTION
In view of the foregoing, the present invention, through one or more of its various aspects, embodiments, and/or specific features or sub-components, is thus intended to bring out one or more of the advantages as specifically noted below.
An object of the present invention is to provide a mobile terminal with the capability of detecting the presence of a user, and notifying the user of the occurrence of an event when the user is present.
To achieve at least this object, there is provided a mobile terminal having an event notification function, which includes a user presence sensor that detects the presence of a user of the mobile terminal, a controller that detects the occurrence of a predetermined event, switches the user presence sensor on when it detects the occurrence of the predetermined event, and generates a control signal to notify a user of the occurrence of the predetermined event when the user presence sensor detects the presence of the user, and an output unit that receives the control signal and notifies the user of the occurrence of the predetermined event.
The user presence sensor may include a motion detector. The motion detector may be a three-axis acceleration sensor. The controller may generate the control signal when a detected motion variation value is equal to or greater than a predetermined reference value.
The predetermined event may be one of a missed call event and a message reception event. The controller may stop notification by the output unit to the user upon receiving a predetermined interrupt signal. The interrupt signal may be generated when the user manipulates an input unit or when the user opens a cover of the mobile terminal.
The output unit may output a predetermined sound and/or a vibration to notify the user of the occurrence of the predetermined event. The output unit may switch on a light emitting diode (LED) contained in the mobile terminal, or cause the LED to blink to notify the user of the occurrence of the predetermined event.
The user presence sensor may include a temperature sensor that detects a body temperature of a user. The temperature sensor may be a contact type temperature sensor or a non contact-type temperature sensor. The temperature sensor may sense a body temperature of the user when it comes into contact with the user, or it may sense a body temperature of the user when it comes within a certain distance of the user.
There is also provided a method for notifying a user of a mobile terminal of the occurrence of an event which includes detecting the occurrence of a predetermined event, detecting the presence of the user of the mobile terminal after the occurrence of the predetermined event has been detected, and notifying the user of the occurrence of the predetermined event when the presence of the user has been detected.
Detecting the presence of the user may include detecting a motion of the mobile terminal. The motion of the mobile terminal may be detected by a three-axis acceleration sensor contained in the mobile terminal. Detecting the presence of the user may include determining whether a motion variation value of the mobile terminal is equal to or greater than a predetermined reference value.
The predetermined event may include a missed call event or a message reception event. Notifying the user of the occurrence of the predetermined event may include outputting a predetermined sound and/or a vibration, or switching on a LED contained in the mobile terminal or causing the LED to blink.
The method may include stopping the notification to the user of the occurrence of the predetermined event upon receiving a predetermined interrupt signal. The interrupt signal may be generated when the user manipulates an input unit or when the user opens a cover of the mobile terminal.
Detecting the presence of the user may include detecting a body temperature of the user. The body temperature of the user may be detected when a contact type sensor of the mobile terminal is brought into contact with the user, or may be detected when a non-contact type sensor of the mobile terminal is brought within a certain distance of the user.
There is also provided a computer readable medium which stores a program for notifying a user of a mobile terminal of the occurrence of an event. The program includes event detection code that detects the occurrence of a predetermined event, presence detecting code that detects the presence of the user of the mobile terminal after the occurrence of the predetermined event has been detected, and user notification code that notifies the user of the occurrence of the predetermined event when the presence of the user has been detected. The program may also include notification stopping code that stops the notification to the user of the occurrence of the predetermined event when a predetermined interrupt signal is received.

FIG. 1 is a block diagram illustrating a mobile terminal having an event notification function according to one aspect of the present invention; and
FIG. 2 is a flow chart illustrating a method for notifying a user of a mobile terminal of the occurrence of an event according to one aspect of the present invention



DETAILED DESCRIPTION OF THE INVENTION
Described below is a mobile terminal having an event notification function, and a method for notifying a user of the mobile terminal of the occurrence of an event.
FIG. 1 is a block diagram illustrating a mobile terminal (such as, but not limited to, a cellular phone or PDA) having an event notification function. Referring to FIG. 1, the mobile terminal includes a radio frequency (RF) unit 110, an input unit 120, a user presence sensor 130, a memory 140, an output unit 150, and a display 160.
When a call is placed to the mobile terminal, the RF unit 110 receives a call-connection request signal via an antenna (ANT). The RF unit 110 also receives messages via the antenna (ANT), such as, but not limited to, text messages and messages indicating the receipt of new voice mail.
The input unit 120 functions as a user interface. Non-limiting examples of the input unit 120 include a keypad having number keys and/or function keys, a touch screen display, and a microphone for receiving commands spoken by a user. The input unit 120 sends input signals to a controller 170 to control operations of the mobile terminal.
The user presence sensor 130 detects the presence of a user, and may be implemented in a variety of forms. Non-limiting examples include a motion sensor, a temperature sensor (contact or non-contact type), a photosensor, an audio sensor, or a combination of sensors. For example, according to one embodiment, the sensor may take the form of a three-axis acceleration motion sensor which senses planar or spatial movement of the mobile terminal if it is picked up or moved by a user.
The sensor 130 is switched on and off by the controller 170, and provides detection signals to the controller 170.
The memory 140 stores not only programs for controlling operations of the mobile terminal, but also stores input/output (I/O) data generated when the mobile terminal is controlled.
The output unit 150 can provide output in any suitable manner, such as visual, audio or motion. As shown in FIG. 1, the output unit 150 includes a speaker 151, and may also include a vibration motor 152. The output unit 150 is switched on and off by the controller 170. The controller 170 controls the output unit 150 to output a predetermined sound and/or vibrate to notify a user of the occurrence of a predetermined event.
Non-limiting examples of predetermined events which may trigger the controller 170 to control the output unit 150 to notify a user include, but are not limited to, a missed incoming call, receipt of a text message, receipt of an indication that a user has received voice mail, receipt of stock, weather, traffic or news updates (which types of updates could, for example, be preset or pre-selected by a user), or receipt of any other types of messages.
The speaker 151 audibly outputs sounds such as, but not limited to, MIDI sound (e.g., ringtones, sound effects, etc.) and voice data stored in the memory 140. The vibration motor 152 vibrates in response to a control signal from the controller 170.
The display 160 is configured to display various information. For example, when a user misses one or more incoming calls, the display 160 may display information relating to the missed call(s), such as information identifying the caller, and the number of calls the user has missed. The display 160 may also display messages, or listings of messages, received by the mobile terminal.
The controller 170 controls overall operations of the mobile terminal, and performs an event notification function, as described hereinafter in detail.
The controller 170 is programmed to detect when predetermined events have occurred. For example, the controller 170 determines when a user of the mobile terminal misses incoming call(s), and in response thereto, controls the display 160 to display information relating to the missed call(s), such as information identifying the caller, and the number of calls the user has missed. The controller 170 also controls the display 160 to display messages, or listings of messages, received by the mobile terminal.
When the controller determines that a predetermined event has occurred, the controller switches the user presence sensor 130 on. When the user presence sensor 130 detects the presence of a user, the sensor 130 signals the user presence to the controller 170, and the controller 170 notifies the user of the occurrence of the predetermined event. In one embodiment, the controller 170 notifies the user by sending a control signal to the output unit 150 to output a predetermined sound and/or vibrate. In other embodiments, the controller 170 notifies the user of the predetermined event via other methods (such as, for example, sending a control signal to periodically display text or images on the display 160, or cause a light emitting diode (LED) to blink on and off).
In an embodiment in which the user presence sensor 130 is implemented by a motion detector, the motion detector or controller 170 may determine that a user is present by comparing a detected motion variation value with a predetermined reference value, and determine that the user is present when the detected motion variation value is equal to or greater than the predetermined reference value.
In an embodiment in which the user presence sensor 130 is implemented by a temperature sensor, either of a contact-type or non-contact type, the temperature sensor or controller 170 may determine that a user is present when the sensor detects a body temperature value which is equal to or greater than a predetermined temperature value, which may be stored in the memory 140. For example, the predetermined temperature may be 36.5° C., which is the approximate body temperature of a human being.
Alternatively the temperature detected by the temperature sensor may be compared to a range of predetermined temperature values, such as 36.5° C.±A° C., where the value of A may be set by a user.
If the temperature sensor is a contact type sensor, it detects a temperature when it is brought into contact with the user. If the temperature sensor is a non-contact type sensor, it detects a temperature when it is brought within a certain distance of the user.
When the controller 170 receives a predetermined interrupt signal, the controller 170 controls the mobile terminal to stop the event notification processes (for example, controls the output unit 150 to cease outputting the predetermined sound or vibrating, controls the display to cease displaying the text or images, or controls the LED to cease blinking).
The interrupt signal can be generated, for example, when the user manipulates the input unit 120 (such as by pressing a key). If the mobile terminal includes a cover which flips or slides open (such as a “flip phone”) the interrupt signal may alternatively or additionally be generated when the mobile terminal senses that the user has flipped or slid the cover open.
FIG. 2 is a flow chart illustrating a method for notifying a user of a mobile terminal of the occurrence of an event. Referring to FIG. 2, the controller 170 of the mobile terminal detects for the occurrence of a predetermined event at step 201.
If the controller 170 determines that an event has occurred at step S202 (for example, if the user has missed a call or has received a message), it switches the user presence sensor 130 on at step S203.
The controller 170 detects for the presence of the user via the user presence sensor 130 at step S204.
When the user presence sensor 130 detects the presence of the user at step S205, the controller 170 controls the mobile terminal to notify the user at step S206 (such as by controlling the output unit 150 to output a sound or vibrate, controlling the display 160 to display text or images, or causing an LED to blink).
When the controller 170 receives an interrupt signal (such as when a user manipulates the input unit 120, or flips or slides open a cover on the mobile terminal), the controller 170 stops the event notification processes of the mobile terminal.
The mobile terminal and method described above detects the occurrence of a predetermined event, and then notifies the user of the occurrence of the predetermined event when it detects that the user is in the presence of the mobile terminal. Further, although the predetermined events as described above are generally externally generated, such as missed calls or received messages, the predetermined event could be internally generated, such as an operating condition of the mobile terminal (such as, for example, a low battery condition or out of service area condition).
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions.
