FIELD OF THE INVENTION
Embodiments of the present invention generally relates to smart devices and assistive technology. More particularly the invention relates to a system and method to detect position of one or more objects and give its distance in real time in audio form.
BACKGROUND OF THE INVENTION
Smart devices refer to various surveying methods of providing useful information to a person of the surrounding environment, including but not limited to, temperature value, speed of an object (hand-held speedometer), laser scales etc.
There is a lack of such system which can measure the distance between two points and actively provide the measured distance data as an audio output. Such technology has many potential applications in measuring devices used in commercial products, defense, explorations etc. Anywhere the eye cannot see and detect the distance, the proposed system comes in handy to know in real time how far an object is, in terms of a real time audio feedback.
Assistive technology is a term for assistive, adaptive, and rehabilitative devices for humans, people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living independently, or even with assistance. Assistive technology reduces the need for formal health and support services, long-term care and the work of caregivers. Without assistive technology, people are often excluded, isolated, and locked into poverty, thereby increasing the impact of disease and disability on a person, their family, and society.
There are many low-tech visual aids that can help older adults with visual impairment, such as magnifying glasses, a long cane, glasses, optoelectronic reading systems (i.e., video magnifier), large-print books, audiobooks, a touch watch, a phone with enlarged buttons, books in Braille, and walking aids. There are various warning systems available which alerts visually impaired person before collision. However, such system lacks the ability to provide real time audio output and provide suggestions.
Therefore, there is a need for an improved a system and method to detect position of one or more objects and give its distance in real time in audio form, which does not suffer from the above-mentioned limitations. Such system and method should be far more efficient than prior art.
OBJECT OF THE INVENTION
An object of the present invention is to provide a system to detect position of one or more objects and give its distance in real time in audio form.
Another object of the present invention is to provide a method to detect position of one or more objects and give its distance in real time in audio form.
Yet another object of the present invention is to provide a system for converting and providing real time spoken (audio) output of the measured data into relevant units, e.g., speaking out distance from an nearby obstacle or solid body.

The one or more user device (106) already includes microprocessor (1024) for processing and communication capabilities via wired or wireless connections, so that the one or more user devices (106) may be provided with the one or more sensors (104).
In yet another embodiment, the system (100) could be implemented as a distributed system (100) where the one or more sensors (104) the processing module (102) and the user interface (106) may be at disposed at different locations from each other and/or the processing module (102) could be implemented in a server-side computing device or cloud computing environment. It will be appreciated by a skilled addressee that there is multiple arrangement in which the present invention can be implemented, without departing from the scope of the present invention.

In one embodiment of the present invention, the processing module (102) may include AI and deep learning-based trained models using the above data, to compare and assess and update the database based on the received data from the one or more sensors (104) or the internet in real-time.
Figure 2 illustrates a method (200) to detect position of one or more objects and give its distance in real time in audio form. As shown in figure 2, the method (200) begins at step 210 by providing a first signal representative of presence or absence of one or more objects at a distance away from one or more sensors (104) for detecting one or more objects. Figure 3A and figure 3B illustrate information flow and an exemplary implementation of system (100) and method (200) shown Figure 1 and Figure 2, in accordance with an embodiment of the present invention. As shown in figure 3A, the one or more sensors (104) are configured to provide a first signal representative of presence or absence of one or more objects at a distance away from the one or more sensors (104).
Further, as shown in figure 3A, at step 220, the processing module (102) in communication with the one or more sensors (104), configured to receive the first signal from the one or more sensors (104). For example, the one or more sensors (104) may be an ultra-sonic senor, a LIDAR, or a LASER based sensors (104) may emit a sound wave or light which may be reflected from one or more objects and creates a signal called the first signal. However, in absence of any object, i.e., in case, the sensors (104) do not receive a reflected signal within a specified time let’s say within 1 second to 60 second, it may be considered as absence of any objects in vicinity of the one or more sensors (104).
Next, as shown in figure 3A, at step 230, the processing module (102) may determine a distance of the one or more objects from the one or more sensors (104) based on the received first signal, in case of presence of the one or more objects. As stated above, when the reflected signal is occurred within predetermined time period, it suggests that one or more object may be present in front of the one or more sensors (104). Based on the reflected signal, the processing module (102) may determine the distance of the one or more objects from the one or more sensors (104) based on the received first signal.
Next, at step 240, as shown in figure 3B, the processing module (102) is further configured to generate a second signal periodically, indicative of real time distance of the one or more objects from the one or more sensors (104). The processing module (102) may use the communication module (1026) to generate and transmit the second signal periodically. Further, as shown in figure 3B, at step 250, the processing module (102) may be configured to generate a third signal in case of the absence of the one or more objects, indicative of absence of the one or more objects. Later, at step 260, as shown in figure 3B, the processing module (102) is further configured to generate a fourth signal indicative of an alert where the determined distance is less than or equal to a predetermined distance.
Furthermore, as illustrated in figure 3B, at step 270, the user interface (106) in communication with the processing module (102), configured to receive the second signal, the third signal and the fourth signal. The user interface (106) may receive the second signal, the third signal and the fourth signal using the communication module (1026). Next, at step 280, as shown in figure 3B, the user interface (106) may provide a real time audio output indicative of the real time distance of the one or more objects from the one or more sensors (104) based on the second signal. For example, an object is at a distance of 15 feet, and the user is moving towards the object, the user interface (106) after receiving the second signal may determine the user a real time distance of the object. In the present case, the distance may be decreasing since the user is moving towards the object and the user interface (106) after some time may determine the distance as 10 feet and later 8 feet and so on.
Further, at step 290, as shown in figure 3B, the user interface (106) may be configured to provide a real time audio output indicative of the absence of the one or more objects, based on the third signal. At this step, the processing module (102) may provide the third signal and based on this signal, the user interface (106) may provide an audio or vibration alert indicating absence of the one or more objects. For example, in this case, the signals from the one or more sensors (104) may not reflect and read within a predetermined time period.
Further, as shown in figure 3B, at step 300, the user interface (106) receives fourth signal and provide a real time audio output indicative of the location of the one or more objects at being at the location equal to or less than the predetermined distance, based on the fourth signal. For example, in case, the one or more objects are dangerously close to the user, the user interface (106) may rapidly give alert and real time distance in order for the user to avoid collision.
In an additional or alternative embodiment, the user interface (106) is configured to provide a warning signal suggestive of probable collision with the detected one or more objects at the location equal to or less than the predetermined distance. For example, the one or more objects are at a distance of 1 or 2 feet which is less than the predetermined distance of 3 feet to 5 feet, the processing module (102) may provide warning signal to the user interface (106). The user interface (106) may use audio output and/or vibrational output to alter the user about incoming one or more objects to avoid collision.
In an additional or alternative embodiment, the one or more sensors (104) are further configured to provide a fifth signal indicative of an empty space near the one or more sensors (104). For example, in case of busy road or crowded area, the one or more sensors (104) may detect an empty space and provide the fifth signal about empty space in crowded area or busy road. On reception of the fifth signal, the processing module (102) may generate a signal of safety to the user to guide the user to the empty space. The audio output and vibration output may provide direction to the empty space to the user to avoid the heavy crowd and the busy road.
In an alternative or additional embodiment, the processing module (102) is configured to receive the second signal, the third signal and the fourth signal and provide a suggestive signal to the user interface (106), indicative of an empty space and/or a suggested path to dodge the detected one or more objects. For example, on reception of the suggestive signal, the processing module (102) may determine a path for the user to guide the user through a non-colliding and safe path to travel. The processing module (102) may provide the suggestive signal to the user interface (106) to provide an audio output and/or vibrational output to the user to guide the user through the crowded places and busy roads.
Further, figure 4 illustrates an exemplary implication, in accordance with an embodiment of the present invention. As shown in figure 4, the one or more sensors (104) may be disposed on a wearable to be worn by the user. The one or more sensors (104) may gather the first signal and send it to the processing module (102) inbuilt in the wearable. The processing module (102) may function the same way as disclosed above and prove the second signal, the third signal, the fourth signal, the suggestive signal, the warning signal, and the fifth signal for the user. The wearable may be provide with audio and or vibrational output (402) to process the signals from the processing module (102) and provide audio/vibrational output as disclosed above.
Further, figure 5 shows a flow chart illustrating an exemplary implementation, in accordance with an embodiment of the present invention. The system (100) may be stand-alone, easy to use wearable product, or disposed on vehicles. The user can switch it ON and go about their regular commutes, meanwhile, it keeps scanning the nearby environment of the user and helps them navigate by notifying the user about any obstacle coming in the vicinity of 10-15 feet, with a real time spoken guidance of the path. The system (100) is highly robust and active may have a refresh rate of range 10 milliseconds to 500 milliseconds and hence giving an immediate response. Various usage cases elaborating the output depending on the obstacle distance -
1. Normal walking (Clear) – When no obstacle is in the vicinity of the user up to 10 feet, the system (100) may respond: clear for 10 feet-15 feet.
2. Something in between (3-10 feet) –
When any obstacle is encountered in the path of the user, the system (100) detects it, calculates the distance from the user and speaks the distance out through the speaker and or vibrational output, the response is obstacle at X feet (between 3 feet to 10 feet).
Now, if the obstacle is not moving with respect to the user, i.e., effective distance is constant, then the device stays silent for certain iterations (5-10 seconds, depending on the distance) and loops back again to give another notification.
3. Something very close (>3 feet)
In case of something being closer than 2-3 feet to the user, the user receives an alert signal from the system (100) through the speaker along with the vibration alert from the direction of the obstacle. (The vibrational output vibrates from back or front if the obstacle is in back or front respectively).
Other Potential applications of the concept such as car parking sensor assembly with distance sensors (104) mounted on front and back of the car and a speaker inside, giving real time spoken feedback notifying the driver about the distance remaining between the car and wall/obstacle. Further the system (100) may be implemented as a hand-held sensor and speaker assembly, like a torch to measure any distance. Furthermore, the system (100) may be used in exploration jacket or can be used by firefighters in smoky conditions and by cave explorers operating in the dark, also, by defense personnel. Basically, anywhere the eyes can’t be used to detect the distance, the concept of the system (100) comes in handy to know in real time how far is anybody in terms of a real time audio feedback.
In this manner the present invention may provide various advantages. The present invention provides cost effective and precise approach to provide safety to the user without visual abilities. The system can give sense in a complete dark place. Further, the system can increase situational awareness of any person by making him/her aware in advance based on artificial sensors. With better situational awareness, the system can help a person to make better decisions about their location.

determining (230) a distance of the one or more objects from the one or more sensors (104) based on the received first signal, in case of presence of the one or more objects;
generating (240) a second signal periodically, indicative of real time distance of the one or more objects from the one or more sensors (104);
generating (250) a third signal in case of the absence of the one or more objects, indicative of absence of the one or more objects;
generating (260) a fourth signal indicative of an alert where the determined distance is less than or equal to a predetermined distance;
receiving (270) the second signal, the third signal and the fourth signal;
providing (280) a real time audio output periodically indicative of the real time distance of the one or more objects from the one or more sensors (104) based on the second signal;
providing (290) a real time audio output indicative of the absence of the one or more objects, based on the third signal; and
providing (300) a real time audio output indicative of the location of the one or more objects at being at the location equal to or less than the predetermined distance, based on the fourth signal.
8. The method (200) as claimed in claim 7, comprising step of providing a warning signal suggestive of a change in the distance between the one or more objects and the one or more sensors (104) and probable collision with the detected one or more objects at the location equal to or less than the predetermined distance.
9. The method (200) as claimed in claim 7, comprising step of providing fifth signal indicative of an empty space near one or more sensors (104).
10. The method (200) as claimed in claim 7, comprising step of:
receiving the second signal, third signal, and the fourth signal; and
providing a suggestive signal, indicative of an empty space nearby and/or suggested path to dodge the detected one or more objects.
