`ABSTRACT
`Methods and apparatuses for operating a portable device
`based on an accelerometer are described. According to one
`embodiment of the invention, an accelerometer attached to
`a portable device detects a movementof the portable device.
`In response, a machine executable code is executed within
`the portable device to perform one or more predetermined
`user configurable operations. Other methods and appara-
`tuses are also described.

`
`FIELD OF THE INVENTION
`
`[0003] The present invention relates generally to a por-
`table device. More particularly,
`this invention relates to
`operating a portable device using an accelerometer of the
`portable device.
`
`BACKGROUND OF THE INVENTION
`
`[0004] Accelerometers are devices widely used for appli-
`cationsas diverse as vibration monitoring, appliance control,
`joysticks, industrial process control, space launches,satellite
`control, and manyothers. For example, an accelerometer has
`been used in a vehicle as sensor to detect a variety of
`operating conditions while the vehicle is moving.
`
`[0005] As computers have been getting more popular, an
`accelerometer has been used in a computer to sense a sudden
`move, such as a free fall, of a computer. A typical application
`of an accelerometer in a computeris to protect a read/write
`head of a hard drive. However, there has been a lack of
`applications that an accelerometer is used in conjunction
`with software executable within a computer.
`
`SUMMARYOF THE INVENTION
`
`[0006] Methods and apparatuses for operating a portable
`device based on an accelerometer are described. According
`to one embodiment of the invention, an accelerometer
`attached to a portable device detects a movement of the
`portable device. In response, a machine executable code is
`executed to perform a predetermined user configurable
`operation.
`
`[0007] According to one embodimentof the invention, an
`accelerometer of a portable device may constantly or peri-
`odically monitor the movementof the portable device. As a
`result, an orientation of the portable device prior to the
`movementand after the movement maybe determined based
`on the movement data provided by the accelerometer
`attached to the portable device.
`
`[0008] According to another embodimentofthe invention,
`an accelerometer may be used to detect a movementof a
`portable device as a way to trigger whether a page of
`document or image may be displayed.
`
`[0009] According to another embodimentofthe invention,
`an accelerometer may be used in a navigation application.
`For example, a portable device having an accelerometer
`
`attached therein may be used as a navigation tool to navigate
`arelatively large object or documentthat normally cannot be
`displayed entirely at once within a display of the portable
`device.
`
`{0010] According to another embodimentof the invention,
`an accelerometer may be used in a gaming application,
`where the accelerometer may be used to detect a scene
`change during a video game running within a portable
`device.
`
`{0011] According to another embodimentofthe invention,
`an accelerometer may be used to detect a movementof a
`portable device and an orientation of the portable device
`may be determined based on the movementdata provided by
`the accelerometer. Thereafter, one or more interfaces of the
`portable device may beactivated or deactivated based on the
`determined orientation after the movement.
`
`{0012] According to another embodimentof the invention,
`an accelerometer may be used to detect and determine
`activities of a user (e.g., joggling) with a portable device
`having the accelerometer attached therein.
`
`[0013] According to another embodimentof the invention,
`an accelerometer may be used to determine whether a
`portable device is moving (e.g., carried by a user) and the
`portable device should be put in a proper operating state
`(e.g., a sleep or hibernated mode).
`
`[0014] According to another embodimentofthe invention,
`an accelerometer may be used to detect whether a portable
`device is moved according to certain directions, in order to
`determine whether a passwordis entered correctly.
`
`{0015] According to another embodimentof the invention,
`an accelerometer may be used to detect and record a
`sequence of movements of a portable device, where the
`recorded movementdata may be usedto recreate the moving
`history subsequently (e.g., off line).

`
`DETAILED DESCRIPTION
`
`[0042] Methods and apparatuses for operating a portable
`device based on an accelerometer are described. According
`to certain embodiments, an accelerometer has been used
`within a portable device, such as, for example, a laptop
`computer, a tablet PC, a personal digital assistant (PDA), a
`cellular phone,and a digital multimedia player, etc. Once the
`accelerometer detects a movementof the portable device, a
`moving direction, also referred to as a moving vector or an
`acceleration vector, is determined based on the movement
`data provided by the accelerometer. The moving direction
`and/or the movement data may be provided to a software
`component (e.g., application software) executed within the
`portable device. In response to the detection of the move-
`ment of the portable device,
`the corresponding software
`component performs one or more predetermined user con-
`figurable actions, such as, for example, advancing a page of
`document, etc., based on the moving direction and/or move-
`ment data provided by the accelerometer.
`
`Someportions of the detailed descriptions which
`[0044]
`follow are presented in terms of algorithms and symbolic
`representations of operations on data bits within a computer
`memory. These algorithmic descriptions and representations
`are the means used by those skilled in the data processing
`arts to most effectively convey the substance of their work
`to others skilled in the art. An algorithm is here, and
`generally, conceivedto be a self-consistent sequenceof steps
`leading to a desired result. The steps are those requiring
`physical manipulations of physical quantities. Usually,
`though not necessarily,
`these quantities take the form of
`electrical or magnetic signals capable of being stored, trans-
`ferred, combined, compared, and otherwise manipulated. It
`has proven convenient at times, principally for reasons of
`common usage,
`to refer to these signals as bits, values,
`elements, symbols, characters, terms, numbers,or the like.
`
`It should be borne in mind, however, that all of
`[0045]
`these and similar terms are to be associated with the appro-
`priate physical quantities and are merely convenient labels
`applied to these quantities. Unless specifically stated other-
`wise as apparent from the following discussion, it is appre-
`ciated that throughout the description, discussions utilizing
`terms such as “processing” or “computing” or “calculating”
