`
`ABSTRACT
`
`A personal fitness monitoring device and a method for
`assessing the fitness of an individual as the individual
`exercises includes using a pedometer to determine and
`output data representing the locomotion of the individual. A
`heart rate monitor determines and outputs data representing
`the heart rate of the individual. A determination arrangement
`calculates the fitness of the individual as the individual
`exercises using personal data provided by the individual in
`combination with the data outputs of the pedometer and the
`heart rate without requiring a predetermined exercise
`regime. In one embodiment, the pedometer calculates a
`distance traveled by the individual using personal data
`provided by the individual. The personal fitness monitoring
`device may further include a user interface for communi(cid:173)
`cating with the user. The user interface uses a single user
`controlled selecting mechanism to select a desired one of
`various user selectable options. The single user controlled
`selecting mechanism is arranged such that the user selects
`the desired option by actuating the selecting mechanism
`during or immediately following the time during which the
`desired option is being presented by the user interface. The
`personal fitness monitoring device may also include a pre(cid:173)
`dicting arrangement for tracking and predicting the fitness of
`the individual.

`PORTABLE AEROBIC FITNESS MONITOR
`FOR WALKING AND RUNNING
`
`BACKGROUND OF THE INVENTION
`The present invention relates to personal fitness monitor(cid:173)
`ing devices. More specifically, the invention relates to a
`personal fitness monitoring device that may be worn by an
`individual while the individual is exercising. The fitness
`monitoring device monitors the aerobic fitness of the user as
`the user exercises and provides the user with information
`about the current exercise session, an assessment of the
`user's current fitness level, and a prediction of the user's
`future fitness.
`
`SUMMARY OF THE INVENTION
`A personal fitness monitoring device and a method for
`assessing the fitness of an individual as the individual
`exercises is herein disclosed. The fitness monitoring device
`includes a pedometer for determining and outputting data
`representing the locomotion of the individual. A heart rate
`monitor determines and outputs data representing the heart
`rate of the individual. A determination arrangement calcu(cid:173)
`lates the fitness of the individual as the individual exercises
`using personal data provided by the individual in combina(cid:173)
`tion with the data outputs of the pedometer and the heart rate
`monitor without requiring a predetermined exercise regime.
`In one embodiment, the pedometer of the personal fitness
`monitoring device includes an accelerometer for measuring
`and outputting data representing the vertical accelerations
`caused by each step of the individual as the individual is 30
`walking or running. A clock is used to segment the output of
`the accelerometer into a time series of data points repre(cid:173)
`senting the output of the accelerometer. A distance determi(cid:173)
`nation arrangement calculates a distance traveled by the
`individual using personal data provided by the individual in 35
`combination with the data outputs of the accelerometer and
`the clock.
`In another embodiment, the personal fitness monitoring
`device further includes a user interface for communicating
`with the user. The user interface includes menus having a
`plurality of various user selectable options available to the
`user for controlling the operation of the personal fitness
`monitoring device. The various user selectable options of the
`menus are successively presented to the user. A single user
`controlled selecting mechanism
`is used for selecting a 45
`desired one of the various user selectable options of the
`menus. The single user controlled selecting mechanism is
`arranged such that the user selects the desired option by
`actuating the selecting mechanism during or immediately
`following the time during which the desired option is being 50
`presented by the user interface.
`In one version of the above described embodiment, the
`arrangement
`for presenting
`the various user selectable
`options to the user is provided by an audio producing
`arrangement which presents the options to the user in the 55
`form of recorded or synthesized speech. This embodiment
`may further include an auxiliary audio fader arrangement.
`The audio fader arrangement has an auxiliary audio input
`connector for receiving an auxiliary audio input signal from
`an auxiliary audio device. A fader, which is controlled by the 60
`operation of the personal fitness monitoring device, connects
`the auxiliary audio input signal to an audio output device
`used by the user interface of the personal fitness monitoring
`device to present the user interface messages. The fader is
`configured to suppress the auxiliary audio input signal when 65
`the user interface of personal fitness monitoring device
`presents a message to the user.
`
`2
`In another embodiment, the personal fitness monitoring
`device further includes a predicting arrangement for tracking
`and predicting the fitness of the individual. The predicting
`arrangement includes a memory arrangement for storing the
`5 data representing the fitness of the individual each time the
`individual exercises using the personal fitness monitoring
`device. A fitness projecting arrangement calculates a pro(cid:173)
`jected fitness of the individual. The fitness projecting
`arrangement uses the stored data representing the fitness of
`10 the individual each time the individual exercises using the
`personal fitness monitoring device to calculate the projected
`fitness of the individual.
`In another aspect of the invention, a pedometer and a
`method for calculating the distance traveled by an individual
`15 as the individual walks or runs is herein disclosed. The
`pedometer includes an accelerometer for measuring and
`outputting data representing the vertical accelerations of
`each step of an individual as the individual is walking or
`running. A clock is used to segment the output of the
`20 accelerometer into a time series of data points representing
`the output of the accelerometer. The pedometer also includes
`a determination arrangement for calculating a distance trav(cid:173)
`eled by the individual. The determination arrangement uses
`personal data provided by the individual in combination
`25 with the data outputs of the accelerometer and the clock to
`calculate the distance traveled.
`In another aspect of the invention, a user interface for use
`in a personal fitness monitoring device and a user interface
`method are herein disclosed. The user interface includes
`menus having a plurality of various user selectable options
`available to the user for controlling the operation of the
`personal fitness monitoring device. An audio producing
`arrangement is used to present the various user selectable
`options of the menus to the user in the form of recorded or
`synthesized speech. A single user controlled selecting
`mechanism is used to select a desired one of the various user
`selectable options of the menus. The single user controlled
`selecting mechanism is arranged such that the user selects
`the desired option by actuating the selecting mechanism
`40 during or immediately following the time during which the
`desired option is being presented in the form of recorded or
`synthesized speech.
`In another aspect of the invention, an auxiliary audio fader
`arrangement and method for use in a personal fitness moni(cid:173)
`toring device which includes an audio user interface for
`presenting user interface audio messages to a user in order
`to interface with the user is herein disclosed. An auxiliary
`audio input connector receives an auxiliary audio input
`signal from an auxiliary audio device. A fader, which is
`controlled by the operation of the personal fitness monitor(cid:173)
`ing device, connects the auxiliary audio input signal to an
`audio output device used by the audio user interface of the
`personal fitness monitoring device to present the user inter(cid:173)
`face audio messages. The fader is configured to suppress the
`auxiliary audio input signal when the audio user interface of
`personal fitness monitoring device presents an audio mes-
`sage to the user.
`And finally, in another aspect of the invention, a personal
`fitness monitoring device and method for tracking and
`predicting the fitness of an individual is herein disclosed.
`The fitness device includes an exertion determining arrange-
`ment for determining and outputting data representing the
`exertion of the individual as the individual is exercising. A

`DETAILED DESCRIPTION
`FIG. 1 shows an embodiment of a fitness monitor 001,
`designed in accordance with the invention. When worn on
`the human body while exercising on multiple occasions over
`the course of many days, fitness monitor 001 provides the
`user, as its primary output, an audio output 003. Audio
`output 003 may take the form of synthesized or digitized
`voice messages detailing the user's current exercise session,
`an assessment of the user's current level of fitness, and a
`prediction of the user's future fitness.
`Fitness monitor 001 takes as primary input certain user's
`personal data 005, an indication of the user's bodily move(cid:173)
`ment 007, an indication of the user's heart rate 009, any user
`selecting actions 011, and an auxiliary audio input 013, all
`15 of which will be described hereinafter. Fitness monitor 001
`has as constituent components a pedometer 015, a fitness
`assessment arrangement 017, a fitness prediction arrange(cid:173)
`ment 019, a user interface 021, and an audio output switch
`023, all of which will also be discussed hereinafter.
`Taking as inputs bodily movement 007 and personal data
`005, pedometer 015 produces a locomotion parameters
`signal 016 representing the users walking or running loco(cid:173)
`motion. Signal 016 indicates locomotion parameters asso(cid:173)
`ciated with each step that the user takes during an exercise
`include
`the gait,
`25 session. The locomotion parameters
`duration, speed, and distance of each step, and optionally,
`grade and terrain characteristics.
`The output signal 016 of pedometer 015 is taken as input
`to fitness assessment arrangement 017 which also takes as
`30 input heart rate indication 009 and personal data 005. The
`fitness assessment arrangement 017 then computes an esti(cid:173)
`mate of the user's current fitness, a measure of the aerobic
`capacity of the user. This output may be expressed in one of
`several common units of measure, including ml oxygen per
`35 minute and kilogram body weight, known as V0 2 , metabolic
`equivalents, known as METs, or any commonly used mea(cid:173)
`sure of indication of fitness, including qualitative measures
`such as "good" or "poor."
`The output of fitness assessment arrangement 017 is input
`40 to fitness prediction arrangement 019, which also takes as
`input personal data 005. The fitness prediction arrangement
`019 produces as output a signal that represents the rate of
`change and future trajectory of the user's aerobic fitness.
`This output is reported on demand to the user through
`45 suitable means according to the particular embodiment of
`the invention, for example as a text display or as pre(cid:173)
`recorded or synthesized speech. However, the format of the
`output is not a requirement of the invention and it may vary
`considerably.
`The fitness monitor 001 also includes a user interaction
`arrangement, user interface 021. User interface 021 provides
`a means for the user to communicate with fitness monitor
`001 by coordinating the timing of a selecting action 011 with
`the temporal period during which a choice is presented. User
`interface 021 provides as an output certain audio messages
`024.
`Finally, fitness monitor 001 includes audio output switch
`023 which takes as input both audio messages 024 of fitness
`monitor 001 and auxiliary audio 013 the user may wish to
`hear. The purpose of the audio output switch 023 is to permit
`users to attend to their desired auxiliary programming yet to
`also permit this programming to be interrupted or faded out
`in order that users can hear important messages initiated by
`fitness monitor 001. For example, users will be able to listen
`65 to a portable tape recorder or radio and to fitness monitor
`001 through the same set of earphones as will be described
`hereinafter.

`While fitness monitor 001 is described as being composed
`of pedometer 015, fitness assessment arrangement 017,
`fitness prediction arrangement 019, user interface 021, audio
`output switch 023, and inputs representing bodily movement
`007, personal data 005, heart rate indication 009, selecting
`actions 011, and auxiliary audio 013, the presence of all of
`these components is not essential to this invention, and the
`existence of certain additional components would be con(cid:173)
`sistent with the invention. For example, a non-audio version
`of fitness monitor 001 could be constructed without the
`requirement of audio output switch 023.
`A version of fitness monitor 001 comprised of any of its
`components alone would be a useful device, for example,
`pedometer 015 alone, or fitness prediction arrangement 019
`alone. Or several constituents could be present, while others 15
`are absent, for example, pedometer 015, fitness assessment
`arrangement 017, and fitness prediction arrangement 019
`would provide a useful fitness monitoring device employing
`some means of user interaction other than user interface 021
`as described herein. Similarly, pedometer 015 is not a
`requirement of the invention because other methods of
`detecting and reporting distance traveled, speed of traveling,
`or expended energy in general might be employed, such as
`global positioning systems or Doppler sound ranging tech(cid:173)
`niques. In a like manner, fitness prediction arrangement 019 25
`is not a requirement of the invention because the fitness
`monitoring function can be fully realized by computing and
`reporting the user's current fitness without regard to or need
`to predict the future trends in fitness.
`In summary, the constituent components of this invention 30
`can be assembled into numerous configurations by including
`some components and leaving others out. All such useful
`combinations would be consistent with the invention. On the
`other hand, the invention may be augmented with additional
`components without changing the nature of this invention. 35
`For example, the invention could include in its function(cid:173)
`ing access to sources of auditory programming, such as
`recorded audio, broadcasts, or digital text that could be
`translated to voice for presentation to the user. That is, the
`invention could include a component designed to provide 40
`the user with pager messages, email messages, and Internet
`information bulletins. Audio messages could also be used
`for encouragement, advice, and inspiration. A remote clin(cid:173)
`ic's computer could send fitness goals and a suggested
`exercise regimen to the fitness monitor 001, which could in 45
`turn report back on compliance with the regimen and fitness
`changes for review by clinic personnel.
`As another example of additional components, the fitness
`monitor 001, when combined with a personal digital assis(cid:173)
`tant scheduling program, could arrange times for the user to 50
`exercise. A home scale could supply body weight, which is
`needed by the fitness monitor 001 for many of its calcula(cid:173)
`tions. A kitchen appliance used for recipes, diet and menu
`planning could give an estimate of dietary fat, which the
`fitness monitor 001 could use in recommending
`fitness 55
`goals, and explaining fitness progress. The fitness monitor
`001 in turn could supply fitness and body weight to the
`dietary computer, which could use them to make dietary
`recommendations.
`While several examples have been cited of additional 60
`components to which the invention might be connected,
`these examples are only indicative of the range of inputs to
`and outputs from the invention described herein. Custom(cid:173)
`ized inputs for these components could be readily provided
`and/or user interface 021 could be designed to accommodate 65
`all of these components
`through one or more auxiliary
`inputs.
`
`6
`The principal advantage of the invention consistent with
`the embodiment as fitness monitor 001 is that previous
`approaches have provided no equivalent function of calcu(cid:173)
`lating fitness while the user is engaged in normal exercise
`5 activity and without the requirement that the user follow a
`specific testing protocol conducted in a specific location in
`order to determine fitness. A further advantage is that, due to
`the ease
