## Background
FIELD OF THE INVENTION
The present invention relates generally to the field of portable electronic devices and, more particularly, to the field of a portable electronic device having visual indicators that are visible from some, but not all, external views.
BACKGROUND OF THE INVENTION
A portable electronic device is capable of interacting with a user and transportable due to its diminutive size and portable power supply. An example of a portable electronic device is a wireless communication device, which provides long-range communication of voice or data over a communication network of specialized base stations to other communication devices remote from the wireless communication device. Portable electronic devices come in a variety of form factors, such as brick, bar, flip/clamshell, slider or rotator/swivel form factors, and each form factor can have a touchscreen or QWERTY keypad. Regardless of the form factor, the device generally includes some type of indicator to convey information to a user or otherwise facilitate the user's use and enjoyment of the device.
Indicators are often used by portable electronic devices as labels to let a user know about certain features or functions the device. For example, one type of indicator is a letter or number label that is provided on a keypad or keyboard. By viewing the indicator, the user may know which number or letter of the alphabet corresponds to the key labeled by the indicator.
Indicators are commonly placed at an outer surface of a portable electronic device so that is in clear view and highly visible. As such, the indicators are always visible and available to the user. On the other hand, many users are capable of remembering the feature or function labeled by an indicator after operating its associated device for an initial time period. Thus, the indicators are primarily useful when a user first learns to use the device and secondarily useful when the user desires a refresher of the labeled feature or function.
Some portable electronic devices attempt to maintain a desirable aesthetic appearance that may otherwise be diminished due to the highly visible indicator. The appearance may be maintained by limiting the times when the indicator is visible. Such devices, however, require active components that have a cost associated with them and the indicator is still highly visible at certain times. Other devices may maintain their desired appearance by creating a removable indicator, but such devices do not provide any type of refresher of the labeled feature or function to the user after the indictor is removed.

It is to be understood that FIG. 2 is provided for illustrative purposes only and for illustrating components of a portable electronic device in accordance with the present invention, and is not intended to be a complete schematic diagram of the various components required for a portable electronic device. Therefore, a portable electronic device may include various other components not shown in FIG. 2, or may include a combination of two or more components or a division of a particular component into two or more separate components, and still be within the scope of the present invention.
Referring to FIG. 3, an embodiment in accordance with the present invention, which is similar to the embodiment illustrated by FIG. 1. In addition to the differing embodiments, the views of the embodiments are also different. FIG. 1 shows an embodiment from a perspective view that shows the front, left and bottom surfaces of the embodiment, whereas FIG. 3 shows a different embodiment (more particularly, a housing 300 of the embodiment) from a different perspective view that shows a front surface 301, a right side surface 303 and a top surface 305 of the embodiment.
As illustrated in FIG. 3, the housing 300 of the portable electronic device includes a groove 307 along the right side surface 303 which is substantially parallel to the top and bottom surfaces 301, 309 and extends the entire length of the right side surface. The groove 301 continues around a top right edge of the housing 300 to the top surface 305 of the housing 300, thus creating a cutout 311. The cutout 311 is actually the portion of the groove 301 that is provided at the top surface 305, including the tapered portion 313 located just before the remaining seam 315 between the upper and lower parts of the device 300. Although the embodiment shown in FIG. 3 illustrates the groove along one side, i.e., the right side surface 303, of the housing 300, it is to be understood that the groove may be provided on the other side, i.e., the left side surface 317, of the device instead, or in addition to, the right side surface.
The groove 307 of the side surface 303 includes a shelf or angled surface 321 that is angled relative to the remainder of the side surface. Also, one or more indicators 323, 325, 327 are located at the angled surface 321 of the side surface 303. The indicators 323, 325, 327 convey information to a user or otherwise facilitate the user's use and enjoyment of the device 100. In addition, the indicators 323, 325, 327 are positioned on the angled surface 321 of the groove 307 to minimize any negative impact on the aesthetic appearance of the device 100. The indicators 323, 325, 327 are tucked away with the angled surface while remaining visible so that they may be viewed when desired. For example, as illustrated in FIG. 3, the indicators 323, 325, 327 and their associated side surface 303 of this embodiment are angled so that they are not directed directly forward toward the front of the device nor directly sideways toward a lateral side of the device. Instead, the indicators 323, 325, 327 and their associated side surface 303 of this embodiment are angled somewhere therebetween. From a front view 329 directly in front of the front surface 301 by a user, the user's view of the indicators 323, 325, 327 is obscured in whole, or in part, by the structure above the indicators. From a side view 331 directly toward the side of the side surface 303 by the user, the user's view of the indicator 323, 325, 327 is askew or distorted due to the angle of the side surface relative to that side view. On the other hand, from a front angled view 333 directly perpendicular to the angled surface 321 or range of angular deviation about the front angled view, the user's view is clear and unobstructed.
For some embodiment, the indicators 323, 325, 327 may communicate functions associated with one or more side buttons or actuators 335, 337 to a user. For example, as illustrated in FIG. 3, an actuator 335 of the first housing may be located in proximity to an associated indicator 323, in which the indicator indicates a function associated with the actuator. The device 100 may include more than one actuator/indicator pair, such as actuator 337 of the first housing which is located in proximity to indicator 327.
For other embodiments, the indicators 323, 325, 327 may dynamically provide status or other information to the user regardless of whether they are within proximity to an actuator 335, 337. For further embodiments, the device 100 may includes a circuit, such as processor 203, and a light source, such as output component 207, coupled to the circuit, in which the light source is capable of illuminating an associated indicator. The circuit may be capable of controlling whether the indicator may be illuminated by the light source. Examples of indicators 323, 325, 327 include, but are not limited to messaging indicators, voicemail indicators, and peripheral indicators.
FIG. 4 is a bottom, planar view of an embodiment in accordance with the present invention. As shown in FIG. 4, the device 100 includes a first housing 401 having an upper surface 403, and a second housing 405 having a lower surface 407 slidably coupled to the upper surface of the first housing. The second housing 405 is capable of sliding to a closed position relative to the first housing 401, as shown in FIG. 4, in which upper and lower surfaces 403, 407 are substantially adjacent and concealed. The second housing 405 is also capable of sliding to an open position relative to the first housing 401 in which only a portion of the upper and lower surfaces 403, 407 are adjacent and concealed and the remainders of the upper and lower surfaces are offset and exposed.
The embodiment includes a groove 413 having one or more indicators located at an angled surface of the groove. The user may have a front angled view 415 directly perpendicular to the angled surface or range of angular deviation 417 about the front angled view. The angle of view would be greater than a direct side view horizontal to the front surface of the device and less than a direct front view perpendicular to the front surface.
FIG. 5 is an enlarged view of a portion 423 of the embodiment of FIG. 4. As shown, the groove 413 includes a first angled surface 501, a second angled surface 503 and a meeting point 505 where the first and second angled surfaces meet. The first angled surface 501 angles downward from the meeting point 505 relative to a horizontal axis 507, in which the horizontal axis is substantially parallel to the front surface of the portable electronic device. The second angled surface 503 angles upward from the meeting point 505 relative to the horizontal axis 507. For clarity and perspective, FIG. 5 also provides a vertical axis 509 that is perpendicular to the horizontal axis 507 and the front surface. The angled surface 501 is angled relative to the horizontal axis 507.
The side surface of the device is coupled to the front surface and, in addition to the first and second angled surfaces 501, 503 of the groove 413, further includes a forward surface 511 between the second angled surface and the front surface and a back surface 513 between the first angled surface and the bottom surface. On the other hand, it is to be understood that the angles and configurations of the embodiment shown in FIG. 5 is intended by example, and the present invention is not restricted by these particular angles and configurations. Generally, there are three partitions to the side surface of the device, namely an angled surface partition 515, a forward side partition or portion 517 and a back side partition 519. The angled surface partition 515 is located between the forward and back side partitions 517, 519. The forward side partition 517 is located between the angled surface 501 and the front surface of the device. The back side partition 519 is located between the angled surface 501 and the back surface of the device. The angled surface 501 is not adjacent to the front surface but, instead, is offset from the front surface since the forward side partition 517 is located therebetween. Since the forward side partition 517 includes a protruding portion 519 located above at least a portion of the indicator relative to the vertical axis 509, the indicator of the angled surface 501 is at least partially obscured by the protrusion when indicator is viewed from the front of the device.
While the preferred embodiments of the invention have been illustrated and described, it is to be understood that the invention is not so limited. Numerous modifications, changes, variations, substitutions and equivalents will occur to those s killed in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
