`ABSTRACT
`
`A digital watch is provided having a viewing display for
`displaying images and including an orientation sensing
`module for sensing angular movementof the watch relative
`to at least one axis of rotation and a control module for
`
`rotating the image displayed on the viewing display to
`maintain the presentation of an image in a substantially
`constant upright orientation when directed (angled) toward
`a primary or secondary viewing person(s). As the useralters
`the orientation of the watch face, the tilt sensor(s) detects the
`change in device orientation. These changes in orientation
`are used to reorient
`the image being displayed on the
`viewing display of the watch.

`
`WATCH ADAPTED TO ROTATE A DISPLAYED
`IMAGESO AS TO APPEARIN A SUBSTANTIALLY
`CONSTANT UPRIGHT ORIENTATION
`
`BACKGROUND OF THE INVENTION
`
`[0001]
`
`1. Field of the Invention
`
`[0002] The present invention relates to a watch adapted to
`rotate the image displayed on the viewing display of the
`watch to maintain the presentation of an image in a sub-
`stantially constant upright orientation when directed
`(angled) toward a primary or secondary viewing person(s).
`
`[0003]
`
`2. Background
`
`[0004] Electronic watches made to include a viewing
`display are becoming increasingly common. Watches are
`now being designed to incorporate the functionality of music
`(MP3) players, digital cameras, photo players, televisions,
`wireless text messaging devices, cellular phones, timers,
`video game devices, PDA’s, GPStracking devices, etc. ...
`Watches such as the Abacus Wrist Net “infowatch” from
`FOSSIL and the N3 spot-watch from SUUNTO exemplify
`the impending push for watches designed for increased
`convenience. This added functionality places greater pres-
`sure on the information displaying methods employed by a
`watch. The current methods used to visually present infor-
`mation to an immediate wearer of a wrist watch or the
`
`in the
`primary user of a pocket watch are insufficient
`redirection of visual media to a secondary viewing per-
`son(s).
`
`[0005] Wrist watches are easily read by their immediate
`wearers. However, it is difficult for a secondary viewing
`person(s) to read from an upside down image presented on
`the viewing display of a wrist watch that is naturally tilted
`toward the secondary viewing person(s). Currently,
`the
`immediate wearer of a wrist watch must unnaturally twist
`their arm around to present the displayed image to a sec-
`ondary viewing person(s) in the upright orientation. The
`requisite physical action of awkwardly rotating a watch 180
`degrees to present an upright image to a secondary viewing
`person(s) located across from the primary viewing person(s)
`is to be remedied by the present invention.
`
`[0006] Pocket watches (and digital stop watches) made to
`include a viewing display are currently designed with a
`single “right side up” orientation. With the current design the
`user must reposition the physical device in order to view the
`displayed image in the upright orientation. The present
`invention would allow for a more userfriendly design as the
`image displayed on the viewing display would remain in the
`upright orientation despite the physical orientation of the
`pocket watch.
`
`[0007] The present invention is directed toward overcom-
`ing one or more of the problemsidentified above. The term
`watchis defined as a portable timepiece and is used through-
`out this application as such. A pocket watch is defined herein
`as a portable timepiece carried in a pocket. A wrist watch is
`defined herein as a portable timepiece worn on the wrist of
`a person (a wearable timepiece).
`
`SUMMARYOF THE INVENTION
`
`[0008] The present invention relates to a method, system,
`apparatus, and article of manufacture for rotating an image
`
`displayed on the viewing display of a watch to maintain an
`upright orientation when directed (angled) toward a primary
`or secondary viewing person(s). The present
`invention
`rotates the image displayed upon the viewing display of the
`watch based on the spatial orientation of the watch with
`respect to a normal gravitational field. A system in accor-
`dance with the principles of the present invention includes a
`watch comprising an information display capable of dis-
`playing a rotated image, an orientation sensing module for
`obtaining the physical orientation of the watch with respect
`to a normal gravitational field and a control module for
`rotating, calculating and driving the electronically displayed
`image. The imageis rotated based uponthe orientation of the
`viewing display of the watch to maintain the presentation of
`an upright image.

`DETAILED DESCRIPTION OF THE
`INVENTION
`
`FIG.1 illustrates a digital wrist watch constructed
`[0018]
`according to the preferred embodimentofthe present inven-
`tion, shown generally at 100. The digital wrist watch 100
`includes a housing 120 having a top, a bottom, a front and
`a back, and a left side and a right side. A strap 106 is
`included for the attachment of the device to the wrist of a
`
`user. A viewing display 101 for displaying images is
`mounted at the top. The viewing display 101 is designed to
`correctly display images rotated in increments of 180

`
`degrees, though a smaller incremental rotation is within the
`spirit and scope of the present
`invention. The viewing
`display 101 is a negative mode multiplexed 32-segment
`LCD. More advanced watches might
`include an OLED
`(organic light-emitting diode) display or a dot matrix LCD
`for visually communicating more information than just the
`“Time of Day”.
`
`The displayed image 201 is also presented in the upright
`orientation as is currently the case with all watches. FIG. 2B
`is a perspective view of the same digital wrist watch 203 as
`that pictured in FIG. 2A, 200 rotated about the axis 220 so
`as to be angled toward a secondary viewing person(s). The
`upside down Logo 205 is included here only to illustrate that
`the watch 203 is tilted toward a secondary viewing per-
`son(s), angled away from the primary viewing person. The
`displayed image 204 is also presented in the upright orien-
`tation as is NOT the case with watches currently on the
`market. The automatic rotation of the displayed image based
`on the physical orientation of the watch to present an upright
`image is noted.
`
`Theorientation of the digital watch 100 is provided
`[0019]
`using an accelerometer 107, such as the ADXL311 dual-axis
`accelerometer device from ANALOG DEVICES, of Nor-
`wood, Mass. Such a device is small in size and may be
`mounted within the housing 120 of the digital watch 100 on
`a plane parallel with the display face. One skilled in the
`[0022] FIG. 3 is a series of side views illustrating the
`relevant art will appreciate that other sensor/accelerometer
`degree to which the wrist watch of FIG. 1 must be rotated
`attachment orientations may be
`implemented without
`about the axis 103 to trigger a 180 degree image rotation.
`departing from the spirit and scope of the present invention.
`Arrowsare placed above the viewing display of the watch
`The accelerometer uses the force of gravity as an input
`vector to determine the orientation of the watch in space
`pictured in each frameofrotation to indicate the orientation
`whenused asatilt sensor to sense static acceleration (e.g.,

`in increments smaller than 180 degrees would do so in
`to display an image that is presented in the upright orien-
`tation to a secondary viewing person(s). The degree oftilt
`response to a rotation about the axis 102 in either thefirst
`105 or the second 109 directions as well as to a rotation
`about the axis 103 at which the image rotates 180 degrees is

`image to be continuously updated. One skilled in the rel-
`evant art will appreciate that the orientation of the digital
`watch 200 can be provided using one or more accelerom-
`eters, or tilt sensors, or tilt switches, or inclinometers, or
`gyroscopesthat are mounted onto or within the digital watch
`200 in various orientations. Some examples of sensors that
`may be used in such a system include an accelerometer
`ADXL320 device from ANALOG DEVICES, of Norwood,
`Mass., a tilt sensing SQ-SEN-001PS device with mechanical
`ball in tube construction from SignalQuest, of Lebanon,
`N.H., a single axis miniature electrolytic tilt sensor of the
`NSMSeries offered by Nanotron, Inc, of Tempe, Ariz., a
`miniature tilt switch D6B from OMRON Electronic, of
`USA,etc. ...
`
`[0023] FIG. 4A-D illustrate a digital wrist watch con-
`structed according to the preferred embodiment of the
`present invention as worn on the wrist of a user. FIG. 4A and
`FIG. 4B show the information being displayed on a seven
`segment LCD. FIG. 4C and FIG. 4D show the information
`being displayed on a segmented LCD designed to mimic that
`of a real analog timepiece. FIG. 4A showsthe right hand of
`the primary viewing person tilting the display face toward
`him or herself to view the image in an upright orientation.
`FIG.4B showsthe right hand of the same primary viewing
`person tilting the display face toward a secondary viewing
`person(s) to present an upright image to a secondary viewing
`person(s). The rotation of the image displayed on the display
`of the wrist watch is noted.
`
`[0020] Adigital watch such as that described herein as the
`preferred embodiment, comprising an orientation sensing
`module employing an accelerometer device for sensing tilt
`about the axes 103, may also be made to function as a
`pedometer or workoutlevel indicator by taking advantage of
`the inertial sensing capabilities of an orientation sensing
`module comprising an accelerometer. This is made possible
`since the accelerometer can sense tilt and also measure
`dynamic acceleration (e.g. vibration), thereby allowing the
`orientation sensing module to function dually as a tilt sensor
`and as an inertial sensing device.
`
`[0021] FIG. 2A is a perspective view of a digital wrist
`watch constructed in accordance with an illustrative embodi-
`
`mentof the present invention. The digital wrist watch 200 is
`shownas being angled toward a primary viewing person or
`the wearer of the wrist watch. Typically, a logo of the
`company producing the watch is printed on the watch itself.
`The Logo 202 is included here only to illustrate that the
`watch 200 is positioned in its natural upright orientation.
`
`[0024] FIG. 5A and FIG. 5B illustrate a digital pocket
`watch constructed according to another embodimentof the
`present invention. The image displayed on the watch face is
`rotated based uponthe orientation of the viewing display in
`two dimensions(pitch and roll) to present an image with an
`upright orientation despite angular reorientation of the hous-
`ing and image display. The image is rotated in increments
`smaller than 5 degrees to continuously present an upright
`image. FIG. 5A showsthe information being displayed on
`a circular segmented LCD designed to mimicthat of a real
`analog timepiece.
`
`FIG.6 is a block diagram illustrating the compo-
`[0025]
`nents resident within, or attached to, the housing 120 of the
`digital watch 100 shownin FIG. 1. With reference to FIG.
`6, it can be seen that the image rotation, orientation data
`processing, timing and information displaying operations
`are controlled by the control module 600 typical of a digital
`watch.In the illustrative embodiment of FIG.6, the control

`
`module 600 includes a power source 607 that includes one
`or more batteries (not shown) or a storage component such
`as a capacitor, a programmable microprocessor unit (MCU)
`603 characterized by a relatively low current consumption
`for extended operation, a watch oscillator 609 comprising a
`watch crystal with a frequency of 32.768 kHz, a memory
`module 604 for storage of program memory and randomly
`accessible variables, a display driver 605 for driving the
`viewing display, a viewing display 606, an audible indicator
`610 such as an externally driven piezo sounder for audibly
`communicating an event and a user control input 608 for
`setting user controlled parameters. The MCU 603 may be
`implemented by either an application specific integrated
`circuit (ASIC) or using a commercially available micropro-
`cessor unit programmed to process orientation information
`and to drive the user interface of the watch. It is the goal of
`the present invention to add orientation sensing, orientation
`data processing and image rotation operations to the func-
`tionality of a digital watch that processes data and drives an
`information display. The orientation sensing module 601
`comprises at least one tilt sensor for sensing angular move-
`ment of the housing relative to at least one axis of rotation
`and to generate an electrical signal representative of a
`change in the physical orientation of the display device.
`
`FIG.7 illustrates an operational flow for an image
`[0026]
`rotation and display processing system according to yet
`another embodimentof the present invention. The process-
`ing begins 700 and a set of readings are obtained in module
`701 in order to determine the orientation of the watch. The
`set of readings are taken for measuring the orientation of the
`watch in at least one dimension. These measurements are
`then processed within module 702 to determine the degree
`to which the watch is rotated about each of the monitored
`axes of rotation. The degree of tilt
`is then compared in
`module 703 with at least one preset numberto determine the
`number of increments that the image must be rotated to
`compensate and in which direction. A corrected bit pattern
`is then generated and loaded into the display driver to drive
`the viewing display with an updated image in module 704.
`
`[0027] While this invention has been illustrated and
`described in accordance with a preferred embodimentof the
`present
`invention,
`it
`is recognized that variations and
`changes may be madetherein. Thus, for example, while the
`illustrative embodiments shown and described herein have
`employed control modules comprised of circuitry typical of
`current digital watches, modification to such circuitry to
`monitor device orientation is implied by the very nature of
`the invention. As such,it suffices to say that the scope of the
`invention disclosed herein should not be limited by the
`specific embodiments illustrated, but rather by the claims
`appended hereto.
