FIG. 1 illustrates a hypothetical frequency analysis of ambient environmental noise in a particular environment.



DETAILED DESCRIPTION
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.
As noted hereinabove, in some environments, ambient noise can make it challenging to hear an auditory alert of an electronic device. Further, in some quieter environments, an auditory alert that might be appropriate for other environments might be inappropriate or grating.
In accordance with one or more preferred embodiments, a methodology is utilized to dynamically determine auditory characteristics, such as volume, sound types, and frequencies, that would be salient to a particular environment based on ambient noise for that environment. In one or more preferred implementations, this comprises determining what auditory characteristics would facilitate discerning, by a person, an auditory alert or other sound generated by the electronic device.
In one or more preferred implementations, this is accomplished by using a microphone to sample ambient noise for the environment, utilizing one or more algorithms such as a Fast Fourier Transform (FFT) in real time, and, based on the results, adapting a ring tone or other auditory alert or sound, e.g. by equalization, to make the ring tone or other auditory alert or sound stand out more with respect to the ambient noise in the environment.
For example, in a preferred implementation, a mobile device would adapt its ring tone to correspond to frequency ranges identified based on sampling of environment ambient noise to be optimal or most salient. In one or more preferred implementations, the ring tone would retain familiar aspects of the selected ring tone, so that a user would recognize the tune or sound, but equalization would change the ring tone to make the sound stand out more against the ambient sound in the environment.
In one or more preferred implementations, analysis and processing is performed entirely at a mobile electronic device, while in at least some other implementations, some or all processing may be performed remotely. In one or more preferred implementations, such processing is facilitated by communication of audio from the electronic device to one or more remote servers. In at least some other preferred implementations, audio is recorded at one or more microphones separate from an electronic device disposed in the same environment as the electronic device, and such audio is processed remotely by one or more computing devices, and results communicated to the electronic device. For example, the environment may be a hospital which has microphones placed throughout one or more areas specifically for the purpose of recording ambient noise for processing. Such processing may occur at a computing device directly connected to one or more such microphones, or at a remote computing device or server.
Implementations in which processing is offloaded from a mobile electronic device are believed to save battery life of such a mobile electronic device. Further, the constant analysis of ambient noise is generally believed to be relatively CPU intensive. Accordingly, in one or more preferred implementations, one or more remote devices make results of FFT or other analysis of environmental ambient noise available to a mobile electronic device on demand in real time, e.g. via WiFi, 3G, 4G, Bluetooth, or other connection.
In one or more preferred implementations, results of FFT or other analysis of environmental ambient noise is preferably made available to an electronic device operating system, such as a mobile device operating system, at any time, e.g. so that a ring tone can be adapted based on the frequency make-up of environmental ambient noise.
In one or more preferred implementations, a frequency spectrum, range, and/or profile of an auditory alert, ring tone, or other sound is adjusted or modified based on a frequency spectrum, range, and/or profile of, and/or frequency analysis of, ambient noise.
Although largely described herein with respect to mobile electronic devices, in one or more preferred implementations methodologies described herein are utilized with a desktop computer. It will be appreciated that methodologies described herein could be utilized with a laptop, tablet, cell phone, PDA, etc.
FIG. 1 illustrates a hypothetical frequency analysis of ambient environmental noise in a particular environment. As can be seen from this graph, there is relatively high power at frequencies around 400 Hz, 1000 Hz, and thin bands around 1500 and 1700 Hz.
Preferably, in this example, a mobile electronic device will adapt its ring tone such that it does not compete with the frequencies in the environment. Accordingly, in a preferred implementation, a ring tone would equalize its frequency spectrum to avoid 400, 1000, 1500, and 1700 Hz (and preferably multiples of these as well). It will be appreciated that this is a simplified example for illustration. The actual analysis of the environmental noise and resulting “suggested” bands by an algorithm would likely be more noisy and complex, and the effects more subtle.
In addition to frequency equalization adjustments, in one or more preferred implementations the attack and decay of a sound is adapted. A harder attack, for example, would make the sound more salient in louder environments, but would be more grating in quieter environments.
In one or more preferred implementations, sampling of ambient noise continuously occurs, or occurs at certain times, while in one or more other preferred implementations, sampling of ambient noise only occurs in response to a determination that a ring tone, auditory alert or other sound needs to be played, or in response to a determination that a ring tone, auditory alert, or other sound was not responded to by a user (e.g. a user did not answer the phone). In one or more preferred implementations, such sampling (and subsequent processing and adaptation) may only be triggered if there is a certain priority level attached to an event, communication, message, or phone call associated with the ring tone, auditory alert, or other sound.
One methodology in accordance with one or more preferred implementations for ensuring that a user will hear a ring tone is to increase the volume of a ring tone, e.g. by continually increasing the volume.
In one or more preferred implementations, volume adjustment is utilized to increase the volume of a ring tone in “loud” environments. Further, in one or more preferred implementations, volume adjustment is utilized to decrease the volume of a ring tone in “quiet” environments. Further, in one or more preferred implementations, a ring tone might be varied, e.g. a different sound or ring tone utilized, based on a “volume level” of the ambient environment.
In one or more preferred implementations, volume adjustment is utilized in combination with other adaptation of a ringtone or other auditory alert or sound. In one or more preferred implementations, an electronic device attempts to find “open” frequency bands in environmental noise, and utilize those such that the amount of volume increase would be as little as necessary.
In one or more preferred implementations, if a determination is made that a user may not be able to successfully hear a ring tone of an electronic device, and an attached severity level of an incoming call (assuming that a severity level or type of severity was available) was high, then automatic action is taken to determine another route to get in touch with a user associated with the electronic device. In one or more preferred implementations, this may include contacting a colleague in a geographically proximate location to inform the colleague that the user needs to be made aware of something.
Based on the foregoing description, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to one or more preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purpose of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications or equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.
