Description
RELATED APPLICATION
[0001] This application is a continuation of U.S. patent
application Ser. No. 09/767,670 filed Jan. 22, 2001.
TECHNICAL FIELD
[0002] This invention relates to a computer input device, and
specifically to an integrated imaging device computer mouse.
BACKGROUND
[0003] A computer mouse is an input and pointing device that
emulates computer keyboard inputs to a computer and enables a user
to translate hand position and movement to control the position of
a cursor on a video display connected to the computer. A computer
mouse offers user convenience to position a cursor, select an input
control, or hi-light text when utilizing a computer application
and/or operating system displayed as a graphic interface on a
computer display. Such interfaces include "Windows", "Macintosh",
and "OS/2".
[0004] A mechanical mouse typically describes a mouse that
incorporates a rubber ball extending from the underside of the
mouse. As the mouse is moved, the rubber ball rotates over a work
surface such as a mouse pad. Inside the mouse, the rubber ball
contacts two rollers mounted perpendicular to each other. The
rollers are moved via the rubber ball when the rubber ball rotates
over the work surface. One roller responds to back and forth
movements of the mouse, which corresponds to vertical movements of
a cursor on a display. The other roller responds to sideways
movements of the mouse, which corresponds to side-to-side movements
of the cursor on the display.
[0005] A conventional mouse typically has one or more input buttons
or switches that can be depressed, or "clicked", to signal a
software application to select an input control or position the
cursor. The input to the application typically depends upon the
position of the cursor on the display. A mouse may also have a
scrolling wheel or roller device controllable by a user that
functions as an input to scroll a display up or down, and also to
operate as an input button when depressed.
[0006] The electrical signals generated within a mouse and
corresponding to a user's hand movements are sent via a cable from
the mouse to the computer. The signals are translated from the
movement of the rollers, via encoders in the mouse, and are
processed with software executing on a processor in the computer to
convert the number, combination, and frequency of signals into the
distance, direction, and speed necessary to move an on-screen
cursor. A mouse can also be wireless in which case the signals are
propagated from the mouse to the computer via infrared or
ultraviolet technologies.
[0007] An optical mouse typically describes a mouse that replaces
the rubber ball, rollers, mechanical encoders, and other mechanical
parts of a mechanical mouse with a digital optical sensor and a
digital signal processor. Rather than relying on the frictional
engagement of the rubber ball on a mouse pad, the optical sensor
senses patterns of light and dark or colors on a specifically
designed mouse pad or work surface. Alternatively, an optical mouse
can be made to operate over any surface that has a random pattern
of relatively light and dark areas.
[0008] As with a mechanical mouse, an optical mouse can be wired or
wire-less, and communicate with a computer via infrared and/or
ultraviolet technologies. An optical mouse can also have any number
of programmable inputs, such as buttons or switches, to effectuate
the input controls of a computer keyboard to a computer.
[0009] A computer mouse is a one-dimensional input and pointing
device having the limited function of emulating computer keyboard
inputs to a computer. Many single-function computer peripheral
devices offer user convenience in exchange for the expense of
purchasing several different devices, and in exchange for work
space. With the ever-increasing need for portable computing in a
limited space, such as on an airplane, in a car, or in a small
office, there is a need for multi-functional, portable and compact
computer peripheral devices.
SUMMARY
[0010] An integrated multi-function computer input device is
described herein.
[0011] In an implementation, an input device operates as both a
pointing device and a scanning device. The input device includes a
first user-selectable switch to activate a first scanning optical
system when scanning an image with the input device in a first
direction relative to a document page. The input device also
includes a second user-selectable switch to activate a second
scanning optical system when scanning the image with the input
device in a second direction that is different than the first
direction.

DETAILED DESCRIPTION
[0019] An integrated computer input device that functions both as a
pointing device and as a scanning device offers user convenience,
multi-function capabilities, and the benefit of saving work space
both in an office and when traveling. A computer mouse having an
integrated scanner makes scanning documents as easy as using a
mouse and reduces user costs with the combined functionality. In
the described embodiments, the computer input device is described
as an optical mouse having a scanner integrated with the mouse.
However, the invention is also applicable to other types of
computer input or pointing devices such as a mechanical mouse, a
trackball, a pen input device, and the like.
[0020] FIG. 1 shows a computing system 10 having a computing device
12 and an optical computer mouse 14 integrated with scanning
components. The computer 12 has a display 16 and a keyboard 18.
Electronic signals generated with the mouse 14 are sent via a cable
20 from the mouse 14 to the computer 12. Additionally, the mouse 14
can receive operational power from the computer 12 via the cable
20.
[0021] The mouse 14 has a housing 22 and programmable buttons, or
switches 24, 26 that are integrated with the housing 22. The
switches 24, 26 can be programmed to control a function of an
application executing on the computer 12, or programmed to control
a function of the mouse 14. For instance, switch 24 operates to
toggle between a first position in which the mouse 14 functions as
a pointing device and a second position in which the mouse 14
functions as a scanning device. The programmable switches 26 are
associated with either the functions of the pointing device or the
functions of the scanning device dependent upon the toggled
position of switch 24 and the selected mode of the input
device.
[0022] A cursor 28 is illustrated as being displayed on the
computer display 16. The switches 26 can be depressed, or
"clicked", to signal a software application to select an input
control or position the cursor 28 on the display 16. Additionally,
the direction of movement of the mouse 14 is translated to the
movement of the cursor 28 on the display 16 when the mouse 14 is
switched to function as a pointing device with switch 24. That is,
moving the mouse 14 to the left or right will move the cursor 28
left or right on the display, respectively. Similarly, moving the
mouse 14 forward and back will move the cursor 28 up and down on
the display.
[0023] The mouse 14 can be implemented with any number of switches
24, 26 and in any number of programmable configurations.
Additionally, the mouse 14 may also have a scrolling wheel or
roller device (not shown) that can also be configured as a
programmable input switch. A mouse having four buttons and a
scrolling wheel would provide a five function selectable
configuration, for example.
[0024] FIG. 2 shows a configuration of the bottom of the optical
computer mouse 14 integrated with scanning components. The mouse 14
has an optical sensor 30 that facilitates the mouse 14 functioning
as a pointing device. The mouse 14 also has scanning optical
systems 32, 34 positioned perpendicular to each other to facilitate
the mouse 14 functioning as a scanning device. The scanning optical
systems 32, 34 can be implemented in any number of configurations.
For example, if the mouse 14 is designed with only scanning optical
system 32, the mouse 14 can be utilized to scan an image by moving
the mouse 14 in a forward and/or back direction. If the mouse 14 is
designed with only scanning optical system 34, the mouse 14 can be
utilized to scan an image by moving the mouse 14 side-to-side over
the image.
[0025] As illustrated, both scanning optical systems 32, 34 can be
implemented together to scan an image in coordination with the
direction of movement of the mouse 14 as detected by the optical
sensor 30. For example, if the optical sensor 30 detects that the
mouse is moving sideways (or horizontally in relation to a
document), scanning optical system 34 is activated to capture the
image. Alternatively, if the optical sensor 30 detects that the
mouse is moving forward or back (or vertically in relation to a
document), scanning optical system 32 is activated to capture the
image. If the optical sensor 30 detects that the mouse is moving in
a diagonal direction in relation to a document, both scanning
optical systems 32, 34 can be activated to capture the image.
[0026] FIG. 3 shows a computing system 40 that illustrates an
example of a wireless optical computer mouse 42 communicatively
linked to the computer 12 via an infrared or ultraviolet
transmission signal 44 that is received at a detector/receiver 46
in the computer. The mouse 42 can also be communicatively linked to
the computer 12 via radio wave technology, such as Bluetooth, for
example. The mouse 42 has a function switch 48 that operates to
toggle between a first position in which the mouse 42 can be
utilized as a pointing device and a second position in which the
mouse 42 can be utilized as a scanning device.
[0027] FIG. 3 illustrates mouse 42 being utilized as a scanning
device as it scans an image 50 on a document page 52. Starting the
mouse 42 at position [X] in the lower right corner of document page
52, the mouse 42 is moved in a direction A, identified by arrow 54,
to a position [Y]. As described above, the optical sensor 30
detects that the mouse 42 is moving forward (or vertically in
relation to document page 52) and scanning optical system 32 is
activated to capture the image 50. The image 50 is displayed on the
computer display 16 as the scanned image 56 while the mouse 42 is
scanning document page 52. Alternatively, the image 50 can be
captured and stored in a memory component in the mouse 42 to be
downloaded to the computer 12 at a later time.
[0028] Multi-functional, user-engageable switches 58, 60 can be
programmed to be associated with a function of the scanning device
when the mouse 42 is switched to the scanning mode. An alternative
to the optical sensor 30 detecting that the mouse 42 is moving in
the direction A, and activating scanning optical system 32, a user
can depress switch 58 to activate the scanning optical system 32
when scanning in a forward or back direction.
[0029] Continuing to scan the image 50 on document page 52, the
mouse 42 moves from position [Y] in a direction B, identified by
arrow 62, to a position [Z]. The optical sensor 30 detects that the
mouse 42 is moving sideways (or horizontally in relation to
document page 52) and scanning optical system 34 is activated to
capture the image 50. Alternatively, a user can depress switch 60
to activate the scanning optical system 34 when scanning in a
sideways direction.
[0030] FIG. 4 illustrates a wireless optical computer mouse 42
being utilized as a virtual scanning device and scanning an image
on an electronic page 64 displayed on computer display 16.
Programmable switch 66 toggles between a document scan mode and a
virtual scan mode when switch 48 is toggled such that the mouse 42
can be utilized as a scanning device.
[0031] In the document scan mode, the mouse 42 can scan an image 50
on a document page 52 as shown in FIG. 3. In the virtual scan mode,
the mouse 42 can scan an image 68, 70 on an electronic page 64.
Electronic page 64 is shown as an Internet Web-site home page for
the Hewlett-Packard Company. However, the electronic page 64 can be
any electronic display that includes text, pictures, hyperlinks,
graphics, tables, frames, and the like that can be virtually
scanned.
[0032] Moving the mouse 42 in a direction C, identified by arrow
72, the image area 68 is captured with the scanning device. Arrow
74 depicted in image area 68 shows the correlation between moving
the mouse 42 in direction C and the resulting scanned image area
68. When moving the mouse 42 in a direction D, identified by arrow
76, the image area 70 is captured with the scanning device. Arrow
78 depicted in image area 70 shows the correlation between moving
the mouse 42 in direction D and the resulting scanned image area
78. The scanned images 68, 70 can be captured and stored in a
memory component in the computer 12, or stored in a memory
component in the mouse 42 to be downloaded at a later time.
[0033] FIG. 5 illustrates the components of an input device 100
having a pointing device 102 and a scanning device 104 integrated
together. In the illustrated embodiment, the pointing device 102 is
an optical mouse having an optical sensor 106 and a digital signal
processor 108. For a mechanical mouse, the pointing device would
have a rotatable ball, rollers, mechanical encoders, and the other
mechanical parts necessary to implement the pointing device as a
mechanical mouse.
[0034] The input device 100 has a power source 110 that can be
derived from a battery source, from a computer over a mouse cable
connecting the input device and the computer, or from any number of
other configurable power sources. For a wireless input device, or
for an input device having a detachable cable, the input device 100
can have an infrared transmitter 112, an ultraviolet transmitter
114, or both. The input device also has a memory component 116 to
store images captured with the scanning device 104.
[0035] The scanning device 104 can be implemented as an optical
scanner that produces machine-readable image data signals that are
representative of a scanned image, such as a photograph or a page
of printed text. The image data signals produced by the scanning
device 104 can be used to reproduce the scanned image on a display
device, such as a computer display or a printer.
[0036] The scanning device 104 has an image illumination component
118 to illuminate an image to be scanned. The illumination
component 118 can be any suitable light source such as a
fluorescent or incandescent lamp, or an array of LEDs (light
emitting diodes) to illuminate the image to be scanned. The
scanning device also has optical systems 120, a photosensitive
detector 122, and an analog-to-digital (A/D) converter 124. The
optical systems 120 include reflective components to direct an
image to be scanned onto a lens assembly.
[0037] The photosensitive detector 122 can be implemented with a
charged coupled device (CCD) designed to detect subtle changes of
light detected when scanning an image and to register the amount of
light as a voltage level that corresponds to a color. The A/D
converter 124 process the voltages generated by the CCD and the
resulting digital signals can then be processed for display and/or
stored in memory 116.
[0038] FIG. 6 illustrates a method to operate an input device that
functions as both a pointing device and a scanning device. As a
pointing device, the input device operates as a computer mouse and
an indicator or cursor position input can be generated with the
mouse at block 200. The cursor position input is translated to move
and/or display a cursor on a computer display at block 202. At
block 204, the functionality of the input device can be switched to
that of a scanning device. When switching the input device to
operate as a scanning device, scanning software can be activated in
a computer that is communicatively linked to the input device at
block 206.
[0039] At block 208, an image can be scanned when the input device
is operating as a scanning device. As described above, the input
device can scan an image in a document scan mode or in a virtual
scan mode when operating as a scanning device. The scanned image
can be displayed on a computer display (block 210) while scanning
the image (e.g., in the document scan mode). Alternatively, the
scanned image can be stored in memory (block 212) to be displayed
at a later time in the form of an electronically displayed image on
a computer display, or as a printed image (block 214) (e.g., in the
document scan mode or in the virtual scan mode).
[0040] Although the invention has been described in language
specific to structural features and/or methodological steps, it is
to be understood that the invention defined in the appended claims
is not necessarily limited to the specific features or steps
described. Rather, the specific features and steps are disclosed as
exemplary implementations of the claimed invention.
