## Background
TECHNOLOGICAL FIELD
An example embodiment of the present invention relates generally to user interface technology and, more particularly, relates to methods, apparatuses, and computer program products for providing broadband audio signals associated with navigation instructions.
BACKGROUND
The modern communications era has brought about a tremendous expansion of wireline and wireless networks. Wireless and mobile networking technologies have addressed related consumer demands, while providing more flexibility and immediacy of information transfer. Concurrent with the expansion of networking technologies, an expansion in computing power has resulted in development of affordable computing devices capable of taking advantage of services made possible by modern networking technologies. This expansion in computing power has led to a reduction in the size of computing devices and given rise to a new generation of mobile devices that are capable of performing functionality that only a few years ago required processing power that could be provided only by the most advanced desktop computers. Consequently, mobile computing devices having a small form factor have become ubiquitous and are used to access network applications and services by consumers of all socioeconomic backgrounds.
With increased functionality, mobile computing devices can be used to perform a variety of functions. For example, some mobile computing devices may be configured to function as a navigation system that provides geographical and/or travel information for a user, such as providing directions to the user.
BRIEF SUMMARY
Unfortunately, however, a navigation function often provides audio or visual navigation instructions that can be distracting to a user. For example, it may be dangerous for a user to glance at a navigation screen to receive a visual navigation instruction when the user is attempting to drive while navigating a route. Likewise, the user may be distracted from what they are listening to (e.g., traffic, alerts, music, etc.) when an audio navigation instruction is broadcast.
As such, example embodiments of the present invention seek to provide navigation instructions with limited distraction to the user. In some embodiments, a user may receive an indication of a navigation instruction in a way that allows the user to understand the navigation instruction without being distracted from their current task. Along these lines, some embodiments of the present invention relate to methods, apparatuses, and computer program products for providing broadband audio signals associated with navigation instructions.
In one example embodiment, a method includes determining a broadband audio signal associated with at least one navigation instruction. The method further includes causing the broadband audio signal to be provided to the user. In some embodiments, the broadband audio signal comprises a representation of an audio signal with components in all frequencies capable of being at least one of perceived or broadcast by a speaker. In some embodiments, the method may include determining the broadband audio signal by determining the broadband audio signal from a plurality of broadband audio signal candidates.
In some embodiments, the method may include determining the broadband audio signal associated with the navigation instruction by, in an instance in which the navigation instruction comprises a continue on the current path instruction, determining a white noise signal. In some embodiments, the method may include determining the broadband audio signal associated with the navigation instruction by, in an instance in which the navigation instruction comprises a turn instruction, determining one of a pink noise signal or a blue noise signal.
In some embodiments, the method may include determining the broadband audio signal associated with the navigation instruction by, in an instance in which the navigation instruction comprises a turn in a predefined direction instruction, determining a pink noise signal. Additionally, in some embodiments, the method may include determining the broadband audio signal associated with the navigation instruction by, in an instance in which the navigation instruction comprises a turn in a second predefined direction instruction, determining a blue noise signal.
In some embodiments, the method may include causing the broadband audio signal to be provided to the user by causing the broadband audio signal to be provided based at least in part on a distance between the user and a location associated with the navigation instruction. Additionally, in some embodiments, the method may include causing the broadband audio signal to be provided to the user by causing the broadband audio signal to be provided at a volume level proportional to the distance between the user and the location associated with the navigation instruction.
In some embodiments, the method may include determining a second broadband audio signal associated with at least one second navigation instruction. Additionally, the method may include causing a transition from the broadband audio signal being provided to the user to the second broadband audio signal being provided to the user. Additionally, in some embodiments, the method may include causing the transition by causing the transition from the broadband audio signal being provided to the user to the second broadband audio signal being provided to the user at a transition rate proportional to a distance between the user and a location associated with the second navigation instruction.
In some embodiments, the method may include determining a second broadband audio signal associated with the navigation instruction. Additionally, the method may further include causing a transition from the broadband audio signal being provided to the user to the second broadband audio signal being provided to the user.
In some embodiments, the at least one navigation instruction may be associated with a first broadband audio signal and a second broadband audio signal.
In some embodiments, the method may further include causing at least one audio navigation instruction associated with the navigation instruction to be provided to the user concurrent with causing the broadband audio signal to be provided to the user.
In some embodiments, the method may further include causing at least one audio navigation instruction associated with the navigation instruction to be provided to the user. Additionally, the method may further include causing the broadband audio signal to cease to be provided to the user concurrent with causing the at least one audio navigation instruction to be provided to the user.
In some embodiments, the method may further include causing at least one visual navigation instruction associated with the navigation instruction to be provided to the user concurrent with causing the broadband audio signal to be provided to the user.
In another example embodiment, an apparatus comprises at least one processor and at least one memory storing computer program code with the at least one memory and stored computer program code being configured, with the at least one processor, to cause the apparatus to determine a broadband audio signal associated with at least one navigation instruction. The at least one memory and stored computer program code are configured, with the at least one processor, to further cause the apparatus to cause the broadband audio signal to be provided to the user.

Additionally or alternatively, the memory 112 may be configured to store program instructions for execution by the processor 110. The memory 112 may store information in the form of static and/or dynamic information. The stored information may include, for example, images, content, media content, user data, application data, and/or the like. This stored information may be stored and/or used by the UI control circuitry 122 during the course of performing its functionalities.
The communication interface 114 may be embodied as any device or means embodied in circuitry, hardware, a computer program product comprising computer readable program instructions stored on a computer readable medium (e.g., the memory 112) and executed by a processing device (e.g., the processor 110), or a combination thereof that is configured to receive and/or transmit data from/to another computing device. In some example embodiments, the communication interface 114 is at least partially embodied as or otherwise controlled by the processor 110. In this regard, the communication interface 114 may be in communication with the processor 110, such as via a bus. The communication interface 114 may include, for example, an antenna, a transmitter, a receiver, a transceiver and/or supporting hardware or software for enabling communications with one or more remote computing devices. In embodiments wherein the apparatus 102 is embodied as a mobile terminal 10, the communication interface 114 may be embodied as or comprise the transmitter 14 and receiver 16 (shown in FIG. 2).

The user interface 116 may be in communication with the processor 110 to receive an indication of a user input and/or to provide an audible, visual, mechanical, or other output to a user. As such, the user interface 116 may include, for example, a keyboard, a mouse, a joystick, a display, a touchscreen display, a microphone, a speaker, and/or other input/output mechanisms. In some embodiments, a display may refer to display on a screen, on a wall, on glasses (e.g., near-eye-display), in the air, etc. In embodiments wherein the apparatus 102 is embodied as a mobile terminal 10, the user interface 116 may be embodied as or comprise the display 28 and keypad 30 (shown in FIG. 2). The user interface 116 may be in communication with the memory 112, communication interface 114, and/or UI control circuitry 122, such as via a bus.
The UI control circuitry 122 may be embodied as various means, such as circuitry, hardware, a computer program product comprising computer readable program instructions stored on a computer readable medium (e.g., the memory 112) and executed by a processing device (e.g., the processor 110), or some combination thereof and, in some embodiments, is embodied as or otherwise controlled by the processor 110. In some example embodiments wherein the UI control circuitry 122 is embodied separately from the processor 110, the UI control circuitry 122 may be in communication with the processor 110. The UI control circuitry 122 may further be in communication with one or more of the memory 112, communication interface 114, or user interface 116, such as via a bus.
The UI control circuitry 122 may be configured to receive user input from a user interface 116, such as a touch display (e.g., touchscreen). The user input or signal may carry positional information indicative of the user input. In this regard, the position may comprise a position of the user input in a two-dimensional space, which may be relative to the surface of the touch display user interface. For example, the position may comprise a coordinate position relative to a two-dimensional coordinate system (e.g., an X and Y axis), such that the position may be determined. Accordingly, the UI control circuitry 122 may determine a position of the user input such as for determining a portion of the display to which the user input correlates.
The touch display may also be configured to enable the detection of a hovering gesture input. A hovering gesture input may comprise a gesture input to the touch display without making physical contact with a surface of the touch display, such as a gesture made in a space some distance above/in front of the surface of the touch display. As an example, the touch display may comprise a capacitive touch display, which may be configured to enable detection of capacitance of a finger or other input object by which a gesture may be made without physically contacting a display surface. As another example, the touch display may be configured to enable detection of a hovering gesture input through use of acoustic wave touch sensor technology, electromagnetic touch sensing technology, near field imaging technology, optical sensing technology, infrared proximity sensing technology, some combination thereof, or the like.
As noted above, the apparatus 102 (shown in FIG. 1) may be configured to perform operations. Indeed, in some embodiments, the apparatus 102 may be configured to function as a navigation system that provides geographical and/or travel information for a user, such as provide directions to the user. In some embodiments, the apparatus 102 may be configured to cause calculation of a route in a map. For example, the user may input a starting location and/or a destination. Then, based on available map data (e.g., from a server or local database), the apparatus 102 may be configured to calculate a route between the starting location and the destination.
In some embodiments, the apparatus 102 (shown in FIG. 1) may be configured to cause presentation of the map, such as on user interface 116. Moreover, in some embodiments, the apparatus 102 may be configured to cause presentation of the calculated route on the map. For example, with reference to FIG. 3, an apparatus 200 may present a portion of a map on a display 201. The apparatus 200 may also present a route 212 on the map. In the depicted embodiment, the route 212 extends from a starting location 214 to a destination 216.
In some embodiments, the apparatus 102, such as through the user interface 116, may be configured to provide navigation instructions to a user. Such navigation instructions may be related to the navigation function of the apparatus 102. Some example navigation instructions include turn left, stay on the current path, turn right, upcoming turn, etc.
Though example embodiments described herein illustrate display of a map and a corresponding route, some embodiments of the present invention do not necessarily need to present the map and/or the route. Indeed, some embodiments of the present invention may be utilized without presentation of navigation information at all.
Considering the usefulness of the above noted navigation features and the ability of users to carry mobile computing devices (e.g., apparatus 102 shown in FIG. 1), users may now rely on their mobile computing devices to get where they need to go. Often, the users may even attempt to utilize the navigation function while driving. In such situations, audio and/or visual navigation instructions may cause unwanted distractions. For example, it may be dangerous for a user to glance at a navigation screen to receive a visual navigation instruction. Indeed, a user may repeatedly look at the navigation screen to, inter alia, (i) ensure that the user has not deviated from the route; (ii) determine how far the user is from a location associated with an upcoming navigation instruction; and/or (iii) determine the direction of an upcoming navigation instruction.
Along these same lines, an audio navigation instruction may interfere with the ability of the user to listen to other sounds, such as traffic, sirens, music, conversation, etc. Likewise, such other sounds may interfere with the audio navigation instruction, thereby making it difficult for the user to receive the navigation instruction.
As such, example embodiments of the present invention seek to provide navigation instructions with limited distraction to the user. Indeed, in some embodiments, a user may receive a navigation instruction in a way that allows the user to understand the navigation instruction without being distracted from their current task, such as may occur if the user were to look at a visual navigation instruction or listen to an audio navigation instruction. In such a regard, the user may easily discern the navigation instruction while maintaining concentration on their current task. Along these lines, some embodiments of the present invention relate to methods, apparatuses, and computer program products for providing broadband audio signals associated with navigation instructions.
As used herein, the term “navigation instruction” may refer to navigation instructions that include commands (e.g., “turn left”, “continue along this path”, etc.). In contrast, a broadband audio signal associated with a navigation instruction may not include a command. Instead, the broadband audio signal, in some embodiments, may be associated with a command such that when a user hears the broadband audio signal, they will know the associated navigation instruction and, thereby, the navigation instruction will be conveyed to the user in a less distracting way.
In some embodiments, a broadband audio signal may be a representation of an audio signal with components in all frequencies capable of being broadcast by a speaker (e.g., a conventional speaker). Additionally or alternatively, in some embodiments, a broadband audio signal may be a representation of an audio signal with components in all frequencies capable of being perceived (e.g., by a human, such as the user). Said differently, the broadband audio signal may have characteristics that cause a user to hear an audio signal that appears to be broadcasting in all frequencies. In such a manner, the broadband audio signal, in some cases, may actually be only broadcast over a certain band of frequencies. Along these same lines, the broadband audio signal may be broadcast such that certain select frequencies are not covered. However, as noted above, the broadband audio signal may still be representative of a broadband audio signal to a user.
Some example broadband audio signals include white noise, pink noise, blue noise, brown noise, among others. White noise is a signal with equal power in any band of a given bandwidth (power spectral density). For example, with a white noise audio signal, the range of frequencies between 40 Hz and 60 Hz contains the same amount of sound power as the range between 400 Hz and 420 Hz. The power density of pink noise, compared with white noise, decreases by 3 dB per octave. In contrast, blue noise, compared with white noise, increases by 3 dB per octave. As such, there is an easy audible distinction between white noise, pink noise, and blue noise. Indeed, a user can easily distinguish between a pink noise signal, a white noise signal, and a blue noise signal. Graphs depicting sound intensity (dB) to frequency (Hz) for white noise, pink noise, and blue noise are illustrated in FIGS. 4A, 4B, and 4C.
In some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine that at least one navigation instruction should be provided to a user. As noted above, the apparatus 102, may be configured to perform a navigation function. As such, the apparatus 102, may determine when a navigation instruction (e.g., turn left, continue along the current path, etc.) should be presented to the user. For example, with reference to FIG. 3, the user 210 may be travelling along a route 212, such as from a starting location 214 to an end location 216. In such a situation, the apparatus 200 may determine that the navigation instruction should be a “continue on the current path” instruction (e.g., continue to travel on the current street).
Though the above described example embodiment details a navigation instruction that includes the user staying on the current path, other navigation instructions are contemplated. Along these lines, other example navigation instructions include the following: turn left, turn right, stop, merge, destination in “X” miles, speed limit is “Y” mph, among others.
In some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine a broadband audio signal associated with the navigation instruction. In some embodiments, the broadband audio signal may be chosen from a plurality of broadband audio signal candidates. In some embodiments, the apparatus 102, may be configured to determine a broadband audio signal associated with the navigation instruction from among the list of broadband audio signal candidates that includes: a white noise signal, a pink noise signal, and a blue noise signal. As an example, with reference to FIG. 3, the apparatus 200 may determine that a white noise signal is associated with the navigation instruction comprising a continue on the current path instruction.
In some embodiments, the apparatus 102, such as through the user interface 116, may be configured to cause a broadband audio signal to be provided to the user. For example, in some embodiments, the apparatus 102 may include one or more speakers configured to broadcast the broadband audio signal to the user. With reference to FIG. 3, the apparatus 200 may include a speaker 208 and may broadcast the broadband audio signal from the speaker 208. For example, the apparatus 200 may broadcast a white noise signal 220 in response to determining that the white noise signal is associated with the navigation instruction of stay on the current path.
As noted herein, in some embodiments the apparatus 102, such as through the processor 110, may be configured to determine other navigation instructions. For example, in some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine that a navigation instruction may comprise an upcoming turn instruction. Additionally, the apparatus 102, such as through the processor 110, may be configured to determine that a broadband audio signal of either a pink noise signal or a blue noise signal is associated with the navigation instruction that the user should turn. For example, with reference to FIG. 4, the apparatus 200 may determine that the user 210 is approaching a left turn 326. As such, the apparatus 200 may determine that the navigation instruction should be a “turn” instruction (e.g., turn left ahead). Additionally, the apparatus 200 may determine that a one of a pink noise signal or a blue noise signal is associated with the navigation instruction comprising a turn instruction. For example, the apparatus 200 may determine that a pink noise signal is associated with a left turn instruction. Further, the apparatus 200 may broadcast the pink noise signal 230.
In some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine, in an instance in which the navigation instruction is a left turn instruction, that a broadband audio signal of a pink noise signal is associated with the navigation instruction. Additionally, in some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine, in an instance in which the navigation instruction is a right turn instruction, that a broadband audio signal of a blue noise signal is associated with the navigation instruction. In such an embodiment, the apparatus 102 may be configured to cause different broadband audio signals for different navigation instructions. Such an embodiment would allow a user to learn to associate the broadband audio signal with the appropriate navigation instruction, thereby allowing for easy determination of a navigation instruction by the user. For example, as shown with respect to FIG. 5, the apparatus 200 may determine a left turn instruction (such as at the left turn 236) and cause a broadband audio signal of a pink noise signal 230 to be provided to the user. Additionally, however, with reference to FIG. 6, after the user takes the left turn at 236, the location of the user 210 may approach a right turn 246. The apparatus 200 may determine a navigation instruction of a right turn instruction and, in response, cause a broadband audio signal of a blue noise signal 240 to be provided to the user. In such an embodiment, the user may travel along the route 212 with the broadband audio signals providing the necessary instructions.
As noted above, some example embodiments provide for associating certain broadband audio signals with certain navigation instructions. For example, a white noise signal may be associated with a continue on the current path instruction, a pink noise signal may be associated with a left turn instruction, and a blue noise signal may be associated with a right turn instruction. In some cases, such an association may be intuitive. For example, with reference to FIG. 4B, the pink noise signal has a relatively high frequency at a relatively low intensity (e.g., it is high on the left side of the graph). Additionally, the blue noise signal has a relatively high frequency at a relatively high intensity (e.g., it is high on the right side of the graph). As such, this provides for an intuitive concept of associating a pink noise signal with a left turn and a blue noise signal with a right turn.
Further, as noted in some embodiments above, the apparatus 102 may be configured to transition between different broadband audio signals based on changes in the navigation instruction. In such a regard, in some embodiments, the broadband audio signal may change between, for example, white noise and pink noise. In such an embodiment, the transition the user recognizes between a continue on the current path instruction (e.g., white noise signal) and either a turn left (e.g., pink noise signal) or a turn right (e.g., blue noise signal) may be intuitive. Indeed, a transition to a pink noise signal or a blue noise signal would be perceived as a deviation from the white noise signal, which corresponds to a deviation in the current path.
In some embodiments, the broadband audio signal may be broadcast to the user in a way that conveys additional information, such as how close the user is to a location associated with the navigation instruction. For example, how close the user is to the upcoming left turn. Along these lines, in some embodiments, the apparatus 102, such as through the processor 110 and/or user interface 116, may be configured to cause the broadband audio signal to be provided to the user based at least in part on a distance between the user and a location associated with the navigation instruction. Additionally, in some embodiments, the apparatus 102, such as through the processor 110 and/or user interface 116, may be configured to cause the broadband audio signal to be provided to the user at a volume level proportional to the distance between the user and the location associated with the navigation instruction. For example, with reference to FIG. 5, the apparatus 200 may provide the pink noise signal 230 at a pre-determined volume level (e.g., a minor level), thereby indicating that a left turn is approaching. Then, with reference to FIG. 5A, as the location of the user 210 approaches the location 236 associated with the left turn, the volume level of the pink noise signal 230′ may increase, thereby indicating that the left turn is close.
In some embodiments, the at least one navigation instruction may be associated with more than one broadband audio signal (e.g., a first and second broadband audio signal). Along these lines, in some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine a second broadband audio signal associated with the navigation instruction. Further, in some embodiments, the apparatus 102, such as through the processor 110 and/or user interface 116, may be configured to cause a transition from the broadband audio signal being currently provided to the user and the second broadband audio signal. For example, with reference to FIG. 5, the apparatus 200 may be configured to cause a white noise signal to be provided to the user, and as the location of the user 210 approaches the upcoming left turn 236, the apparatus 200 may transition from providing the white noise signal to providing a pink noise signal. In some embodiments, the transition may be defined by a transition rate that is proportional to the distance between the location of the user 210 and a location associated with the navigation instruction (e.g., the location of the left turn 236). As such, as the location of the user 210 draws nearer to the left turn 236, the pink noise signal becomes more distinct and overpowering of the white noise signal. This may continue until the user needs to make the left turn, at which point, the pink noise signal may be the only broadband audio signal being provided to the user.
In another example, the apparatus 102 may be configured cause a first broadband audio signal (e.g., a pink noise signal) to be provided to the user as the user approaches the location associated with the navigation instruction (e.g., the intersection of the left turn). Then, once the user reaches the location, the apparatus 102 may be configured to cause a second broadband audio signal (e.g., a white noise signal) to be provided to the user. Further, should the user travel past the location of the navigation instruction (e.g., miss the left turn), the apparatus 102 may be configured to cause a third broadband audio signal (e.g., a blue noise). In such a regard, a Doppler Effect type broadband audio signal system may help the user easily recognize when they miss a turn. In some embodiments, the apparatus 102 may be configured to cause a transition between broadcasting of the broadband audio signal. Additionally, in some embodiments, the apparatus 102 may be configured to cause the transition to occur at a transition rate proportional to the distance between the location of the user and the location associated with the navigation instruction.
In some embodiments, the apparatus 102 may be configured to provide a transition between broadband audio signals for different navigation instructions. In such a manner, the user may become aware of a changing navigation instruction. Along these lines, in some embodiments, the apparatus 102, such as through the processor 110, may be configured to determine that a second broadband audio signal is associated with at least one second navigation instruction. Further, in some embodiments, the apparatus 102, such as through the processor 110 and/or user interface 116, may be configured to cause a transition from the broadband audio signal being currently provided to the user and the second broadband audio signal. For example, with reference to FIG. 3, the apparatus 200 may determine that the navigation instruction is a continue on the current path instruction and, thus, cause a white noise signal 220 to be provided to the user. However, with reference to FIG. 5, as the user (e.g., the location of the user 210) approaches an upcoming left turn 236, the apparatus 200 may determine that the navigation instruction is an upcoming turn instruction. Thus, the apparatus 200 may be configured to cause a transition from the white noise signal to a pink noise signal. In some embodiments, the transition may be defined by a transition rate that is proportional to the distance between the location of the user 210 and a location associated with the navigation instruction (e.g., the location of the left turn 236). As such, as the location of the user 210 draws nearer to the left turn 236, the pink noise signal becomes more distinct and overpowering of the white noise signal. This may continue until the user needs to make the left turn, at which point, the pink noise signal may be the only broadband audio signal being provided to the user.
In some embodiments, the apparatus 102, such as through the user interface 116, may be configured to cause audio navigation instructions associated with the navigation instruction to be provided to the user. For example, the apparatus 102 may be configured to provide an audio navigation instruction that instructs the user to perform an action, such as “Turn Left.”
In some embodiments, the apparatus 102, such as through the user interface 116, may be configured to cause at least one audio navigation instruction associated with the navigation instruction to be provided to the user concurrent with causing the broadband audio signal to be provided to the user. In such a regard, the broadband audio signal and the audio navigation instruction may be provided to the user at the same time. For example, with reference to FIG. 7, the apparatus 200 may determine, such as based on the location of the user 210, that the navigation instruction of a left turn should be provided to the user. As such, the apparatus 200 may cause a pink noise signal 230 (e.g., the associated broadband audio signal) to be provided to the user. Additionally, the apparatus 200 may cause an audio navigation instruction, such as a broadcast of the instruction “Turn Left” 255 to also be provided to the user. Since the broadband audio signal is not disruptive, the user can still understand the audio navigation instruction and be properly instructed.
In some embodiments, the apparatus 102 may be configured to cease broadcasting of the broadband audio signal while the audio navigation instructions are being broadcast. For example, in some embodiments, the apparatus 102, such as through the user interface 116, may be configured to cause at least one audio navigation instruction associated with the navigation instruction to be provided to the user. Additionally, the apparatus 102, such as through the user interface 116, may also be configured to cause the broadband audio signal to cease to be provided to the user concurrent with causing the at least one audio navigation instruction to be provided to the user. For example, in contrast to the embodiment shown in FIG. 7, as the location of the user 210 approaches the left turn 236, the apparatus 200 may cease broadcasting of the broadband audio signal 230 and beginning broadcasting of the audio navigation instruction 255. In such an example embodiment, the user may receive an indication of an upcoming navigation instruction (such as by hearing the broadband audio signal) and, then, when the navigation instruction is pertinent and/or imminent, the user may be able to easily hear the audio navigation instruction.
In some embodiments, the apparatus 102, such as through the user interface 116, may be configured to cause visual navigation instructions associated with the navigation instruction to be provided to the user. For example, the apparatus 102 may be configured to provide a visual navigation instruction that instructs the user to perform an action, such as “Turn Left.”
In some embodiments, the apparatus 102, such as through the user interface 116, may be configured to cause at least one visual navigation instruction associated with the navigation instruction to be provided to the user concurrent with causing the broadband audio signal to be provided to the user. In such a regard, the broadband audio signal and the visual navigation instruction may be provided to the user at the same time. For example, with reference to FIG. 8, the apparatus 200 may determine, such as based on the location of the user 210, that the navigation instruction of a left turn should be provided to the user. As such, the apparatus 200 may cause a pink noise signal 230 (e.g., the associated broadband audio signal) to be provided to the user. Additionally, the apparatus 200 may cause a visual navigation instruction, such as by causing presentation of the instruction “Turn Left” 265 to be provided to the user on the screen 201. In such an example embodiment, the user may receive an indication of an upcoming navigation instruction (such as by hearing the broadband audio signal), which may also inform the user that a visual navigation instruction is being displayed.
