`0035. Preferred embodiments of the present invention are
`described in detail with reference to the accompanying draw
`ings. The same reference numbers are used throughout the
`drawings to refer to the same or like parts. Detailed descrip
`tions of constructions or processes known in the art may be
`omitted to avoid obscuring the subject matter of the present
`invention.
`0036 Although the invention is described in detail with
`reference to specific embodiments thereof, it is to be under
`stood that variations that are functionally equivalent are
`within the scope of this invention. Various modifications of
`the invention in addition to those shown and described herein
`will become apparent to those skilled in the art from the
`following description and accompanying drawings. Such
`modifications are intended to fall within the scope of the
`appended claims.
`0037. In the following, a mobile phone enabled by haptic

`vibration code in its header or body field. A mobile phone
`according to an embodiment of the present invention alarms a
`reception of a text message by extracting a vibration code
`contained in a header or body field of the received text mes
`sage and generates a vibration having a pattern and level
`indicated by the vibration code. Also, the mobile phone
`according to an embodiment of the present invention extracts
`a vibration code contained in a body field of a received text
`message and generates a vibration having a pattern and level
`indicated by the vibration code.
`0039. Although the haptic generation method and system
`are described in association with a mobile phone in the fol
`lowing, the present invention is not limited to the mobile

`0040. For example, the haptic generation method and sys
`tem can be applied to various kinds of mobile terminals such
`as a cellular phone, a portable digital broadcast receiver, a
`Personal Digital Assistant (PDA), a Smartphone, Interna
`tional Mobile Telecommunication 2000 (IMT-2000) terminal
`including Wideband Code Division Multiple Access
`(WCDMA) terminal and CDMA 2000 terminal, a mobile
`Internet Protocol (IP) phone, a Portable Multimedia Player
`(PMP), an MP3 player, a portable computer including laptop
`and palmtop computers, and their functional equivalents.
`0041
`FIG. 1 is a schematic diagram illustrating a mobile
`communication system including mobile phones equipped
`with a haptic generation system according to an embodiment
`of the present invention.
`0042. Referring to FIG. 1, the mobile communication sys
`tem includes a communication network 300 and a pair of
`mobile phones 100 and 500 communicating with each other
`
`Exhibit 1035 - Page 12 of 21

`

`

`US 2008/O153554 A1

`
`via the communication network 300. The first mobile phone
`100 is a sending mobile phone, which transmits a vibration
`code, and the second mobile phone 500 is a receiving mobile
`phone, which receives the vibration code.
`0043. The sending mobile phone 100 and the receiving
`mobile phone 500 can communicate with each other in voice
`and data communication sessions through the communica
`tion network 300. The sending mobile phone 100 and the
`receiving mobile phone 500 are named as such for simplify
`ing the explanation of the present invention. However, their
`structures and functions are identical with each other and
`their roles can be switched.
`0044. In the following, the sending mobile phone 100
`generates a vibration code and transmits the vibration code to
`the receiving mobile phone 500. The receiving mobile phone
`500 receives the vibration code and generates vibration indi
`cated by the vibration code.
`0045. The sending mobile phone 100 monitors to detect a
`haptic function activation command input by its user and
`activates the haptic function in a current operation mode (for
`example, a communication mode, multimedia mode, and
`standby mode) in response to the haptic function activation
`command. Once the haptic function is activated, the sending
`mobile phone 100 detects a vibration event (for example, in
`signal input by a touch event or a key event for vibration) and
`generates a vibration code corresponding to the vibration
`event.
`0046. If a vibration event is detected, the sending mobile
`phone 100 checks a vibration pattern assigned for the vibra
`tion code and outputs a vibration according to the vibration
`pattern. The sending mobile phone 100 also converts the
`vibration code into a control signal of a specific message
`format and transmits the control signal to at least one receiv
`ing mobile phone 500.
`0047. The sending mobile phone 100 can transmit the
`vibration code by means of a text message. For example, the
`sending mobile phone 100 inserts the vibration code into a
`header or other field of a text message to be transmitted to the
`receiving mobile phone 500. The vibration code can be
`inserted into a content of the text message.
`0048. The vibration information including vibration
`event, vibration code, and vibration pattern are explained in
`detail with reference to table 1. The sending mobile phone
`100 can be configured to vibrate or not by an option preset in
`a haptic function setting screen. The haptic function setting
`procedure is described in detail with reference to FIG. 2.
`0049. The communication network 300 receives a control
`message containing the vibration code from the sending
`mobile phone 100 and forwards the control message to at least
`one receiving mobile phone 500 located within its service
`area with reference to destination information of the control
`message. The message delivery procedure is described in
`detail with reference to FIG. 2.
`0050. When the control message is a text message, the
`communication network 300 transmits the text message to at
`least one receiving mobile phone 500 indicated by destination
`information contained within the text message. The text mes
`sage contains the vibration information in the header or other
`specific field in a specific code format. The vibration infor
`mation is added for transmitting a tactile expression.
`0051. The communication network 300 may composed of
`at least one Base Station (BS), a Base Station Controller
`(BSC), a Mobile Switching Center (MSC), a Home Location
`
`Register (HLR), and an information server such as a Short
`Message Service Center (SMSC).
`0.052 With such structure, the communication network
`300 supports the wireless communication between the mobile
`phones 100 and 500. For example, the communication net
`work 300 supports a communication channel between the
`sending mobile phone 200 and the receiving mobile phone
`500 and processes the voice and data exchanged between the
`two mobile phones 100 and 500. The communication net
`work 300 also provides support for establishing multimedia
`communication channels (e.g., traffic channels) between the
`two mobile phones 100 and 500 such that the multimedia
`packets including text message and still and motion pictures
`can be exchanged through the multimedia communication
`channel. More particularly, the communication network 300
`supports the CMS such that the mobile phones 100 and 500
`can exchange the text messages and still and motion pictures
`through separate channels during a voice communication
`session.
`0053. The communication channel can be established in
`accordance with the communication technology adapted to
`the communication network. The communication network is
`composed of at least one of CDMA, Frequency Division
`Multiple Access (FDMA), Time Division Multiple Access
`(TDMA), WCDMA, Universal Mobile Telecommunication
`System (UMTS), Orthogonal Frequency Division Multiple
`Access (OFDMA), Wireless Broadband Internet (WiBro)
`systems.
`(0054) The receiving mobile phone 500 receives the control
`message containing the vibration code forwarded by the com
`munication network 300 and extracts the vibration code from
`the control message if its tactile feedback function is acti
`vated. After extracting the vibration code, the receiving
`mobile phone 500 retrieves a vibration pattern matched to the
`vibration code from a mapping table and outputs a vibration
`according to the vibration pattern.
`0055 When receiving a text message via the communica
`tion network 300, the receiving mobile phone 500 determines
`whether a vibration code is contained in the header or another
`specific field of the text message. If a vibration code is
`detected, the receiving mobile phone 500 checks the vibration
`pattern/level indicated by the vibration code and then outputs
`a vibration according to the vibration pattern/level for alarm
`ing the reception of the text message.
`0056. If a text message open command is detected, the
`receiving mobile phone 500 displays the text message. The
`receiving mobile phone checks whether a character String is
`registered with a vibration pattern and outputs, if a character
`string registered with a vibration pattern is detected, a vibra
`tion according to the vibration pattern.
`0057. As described above, the haptic generation method
`and system of the present invention allows tactile communi
`cation in addition to the conventional visual and auditory
`communication, thereby delivering tactile feelings as well as
`visual and auditory expressions, resulting in enriching com
`munication.
`0.058 Although the mobile communication system
`depicted in FIG. 1 shows a communication network bridging
`two mobile phones, the present invention is not limited to
`Such configuration. For example, the haptic generation
`method and system of the present invention can be applied to
`a mobile communication system composed of a plurality
`fixed and mobile terminals such that the mobile communica

`
`tion network delivers the vibration code received forma send
`ing mobile terminal to multiple receiving mobile terminals
`simultaneously.
`0059 Also, the sending mobile phone 100 can be config
`ured to request a call to a phone number of the receiving
`mobile phone 500 with a vibration code (for example,
`XXX011-123-4567 or 011-123-4567). In such case, the com
`munication network 300 transmits a call request message
`having the vibration code to the receiving mobile phone 500.
`Accordingly, the receiving mobile phone 500 extracts the
`vibration code from the call request message and outputs a
`vibration according to the vibration pattern/level indicated by
`the vibration code for alarming an incoming call. By mapping
`the vibration code to different vibration patterns/levels, the
`sending user can deliver emotional expression to the recipi
`ent
`0060. The mobile phone can be provided with a vibration
`code generation part, vibration output part, and vibration
`information storage part. A mobile phone equipped with a
`haptic feedback system according to an embodiment of the
`present invention is described hereinafter.

`0067. The RF unit 210 is responsible for an RF commu
`nication of the mobile phone 200. For example, the RF unit
`210 establishes a communication channel with the commu
`nication network for data and Voice communications with
`another mobile phone. The RF unit 210 includes an RF trans
`mitter for up-converting and amplifying a transmission signal
`and an RF receiver for low-noise amplifying and down-con
`Verting the received signal.
`0068. The data processing unit 220 is responsible for pro
`cessing the Voice data received from the audio processing unit
`230, alphanumeric data input by the input unit 240, and data
`(for example, vibration code, control message, and text mes
`sage) received and to be transmitted through the RF unit 210.
`The data processing unit 220 includes a transmitter for per
`forming encoding and modulation on the signal to be trans
`mitted through RF unit 210 and a receiver for performing
`demodulation and decoding on the signal received through
`the RF unit 210. The data processing unit 220 may include a
`
`modem and a codec. The codec is provided with a data codec
`for processing packet data and an audio codec for processing
`audio signal including Voice.
`0069. The audio processing unit 230 processes audio sig
`nal received from the data processing unit 220 so as to be
`output as an audible sound wave through a speaker (SPK) and
`processes the Sound wave input through a microphone (MIC)
`So as to be output audio signal to the data processing unit 220.
`(0070. The input unit 240 is provided with a plurality of
`alphanumeric keys for inputting number and text information
`and various function keys for generating control command
`for executing corresponding functions. The input unit 240 can
`be provided with at least one of touchpad, touchscreen, and a
`keypad. The input unit 240 can further includes navigation
`keys, Volume keys, and various hotkeys. In this embodiment,
`the input unit 240 is configured such that the haptic function
`can be set through key manipulation on the keypad, touchpad,
`or touchscreen. In a case that the haptic function is activated,
`the vibration event for generation vibration code can be input
`using the function keys provided on the keypad, touchpad, or
`touchscreen.
`0071. The memory unit 250 stores application programs
`for executing functions of the mobile phone (particularly, the
`application programs for controlling the haptic function) and
`user data (for example, photo, motion picture, and text mes
`sage) generated by the user or received from outside. The
`memory unit 250 also stores the parameters associated with
`the haptic function. The memory unit 250 can be provided
`with at least one buffer for temporarily storing the user data
`generated while the application programs are operating.
