TECHNICAL FIELD
[001] The present disclosure relates to field of electronics engineering to be used as a
communication tool for disabled person. More particularly, the present disclosure relates to an apparatus to enable disabled person to transmit messages.
BACKGROUND
[002] There have been times when a person is so much disabled that he has to be
confined in a wheel chair. Such person is observed for struggling for performing day to day activities. Although there are many inventions developed that tend to comfort such person like automatic wheel chair but most of such are operated with the help of the hands. The situation becomes worse when such a disabled person has his hands also not working properly. The controlling of wheel chair with the help of gestures is still possible due to numerous innovations being carried out in the field. The problem being solved by these innovations are only confined to locomotion of the disabled. What if such a person wants to transmit his audio message such as his call for help, to a person standing at a little distance? The disabled person has to operate the wheel chair and make a move in order to convey his/her message. He has to move from his place and reach the other person to communicate his voice. This might take some time to convey his message. Moreover, sometimes it is not even possible physically by a disabled person to reach to that person, such as if he is standing above some stairs or is too far.
[003] In order to provide a some more technological solution to provide comfort to
the disabled-person, automated wheel chairs are also invented which are operated either by a
remote control by the disabled person itself or by a remote person operating the remote
control and standing at a certain distance. If the disabled person is to operate the remote
control only but the disabled person who has disability in his hands also, he is unable to use
the remote control. So, audio/voice message is very difficult to transmit.
[004] Disabled person usually has to call or use a wheel chair to convey his message
to a person standing at a certain distance. Communication by shout requires lots of physical energy to be utilized. Moreover, disabled person might not be able to call loudly as per his/her situation. On the other hand, if disabled person has to convey his/her message to a distant person using wheelchair, disabled person has to move the wheels to provide a rotation to the wheels. It also involves a requirement of lots of physical effort to be done by disabled

person. Automated chairs are also an option to be operated by disabled but if disabled are not even able to use his/her hand to operate the controller such as joystick/remote controller to control the automated chair, he/she might not be able to convey his/her message to a distant person.
[005] Even if disabled can operate automated wheelchair, there may be a case that
the disabled person might not have hands or hands are permanently disabled to operate the same. If a disabled can barely move is hand, he/she might not be able to convey his/her message to a person standing at a certain distance.
[006] Efforts have been made in the past to overcome problem associated with
controlling vehicles. For example, United States Patent Number US 20160214713 Al discloses and unmanned aerial vehicle having multiple propellers over the body of UAV is equipped with LED, multiple speakers, laser light, strobe light, video screen, video camera, voice recording and storage capability. The said UVA has a computer control module for wireless communication with a remote-control device. The prior art discloses a simple UAV having various features wherein the UAV is controlled by a remote control. In case the person is disabled and unable to use the remote control, the disclosed prior art cannot be used. Whereas, in the present invention, an electronic wearable control band is to be worn by a disabled person at appropriate place wherein the wearable electronic band is configured with various distance based signals generated with respect to ground by a disabled person after wearing which acts as a trigger to activate appropriate signal captured by a hovering device at defined distance range and performs appropriate task accordingly to convey his/her message to a person situated at a distance.
[007] WIPO Patent Application Number WO 2017172185 Al discloses an electronic
wearable wrist band having pressure sensors to be worn by a person and configured to provide a signal to a verity of apparatus such as vehicle or drone to perform specific task. The pressure sensors upon being pressed by the muscle of the wearer generates an electrical signal that is processed and captured by a receiving unit embedded over drone or vehicle. The communication between electronic wearable device and the receptor unit is through various means of communication systems such a Li-Fi. The prior art includes a pressure sensor which when pressed by a wearer generates an electronic signal that initiates the working of the vehicle or drone. If a person is unable to initialize the pressure sensor by his/her muscle because of the deformities of his/her hand, controlling signals will not be generated. Whereas, in the present invention, pressure sensors are not used but the IR based LED configured to

detect verity of distance-based signal between electronic wearable band and ground and
accordingly provide to a distant hovering device to activate appropriate task to be performed.
[008] There is, therefore, a need in the art to provide an apparatus which can
promote the disabled person to convey his/her message to a distant person without much physical effort.

[0040] FIG. 1 illustrates an exemplary representation of a hover device/vehicle in
accordance with an embodiment of the present disclosure.
[0041] In an embodiment, a hover device/vehicle 100 can include a decoding unit, a
microphone 104, a speaker 106, a second IR LED 108 in direct communication with
decoding unit about the distance between hovering device 100 and wearable electronic
controller 202 and a signal reception unit 102 with antennas as well as small-sized convex
mirrors placed on to the hover device for increasing the magnitude of the received LIFI
signal.
[0042] In an embodiment, in order to control a hovering device 100, FIG. 1 shows a
flexible wearable electronic controller 202 to be worn over the suitable body part of disabled
person. The said wearable electronic controller 202 has a FIBERO unit which is a motion
sensing module. As soon as wearable electronic controller 202 is worn over the body of
disabled person, the motion sensor senses the motion and transmits a command using
communication unit 212 to the hovering device 100 to initiates hovering process of the
hovering device 100.
[0043] FIG. 2A illustrates an exemplary representation of the flexible controller worn
by a user in accordance with an embodiment of the present disclosure.
[0044] In an embodiment, A flexible wearable electronic controller 202 having a
motion sensing module, a button 208, pluralities of IR LED 206 and a communication unit
212 containing antenna and other supported electronics for LIFI signal transmission.
[0045] FIG. 2B illustrates an exemplary representation of the flexible controller
diagram in accordance with an embodiment of the present disclosure.
[0046] Plurality of IR LED 206 at the surface of wearable electronic controller 202
emit IR radiations towards ground. During the working of the wearable electronic controller
202, the IR radiation could strike the ground and returns back to its fixed position i.e. the
bottom of wearable electronic controller 202. The measurement of vertical distance of the IR
LED 206 from the ground is easily calculated using formula as
[0047] D = c * t/2
8

[0048] where d is the distance to be find, c is the velocity of light and t is the time
taken by the light to rebound back to its original position.
[0049] In an embodiment, for various distance ‘d’ can be referred as D1 in the FIG.
2B from the ground, the wearable electronic Controller 202 is configured and comprises the
appropriate task to be perform by the hovering device 100 such as forward and backward
movement.
[0050] Another distance ‘d’ referred as D2 in the FIG. 2B from the chest of the
wearer, the wearable electronic controller 202 is configured comprises the appropriate task to
be perform by the hovering device 100 such as left and right movement.
[0051] As defined in the console of the wearable electronic controller 202, the
distance between the hovering device 100 and the ground 210 is always maintained at 1
meter. For the same, IR LED 206 is placed at the bottom side of the hovering device 100
which keeps reverting to the decoding unit of the hovering device 100 about the distance
between hovering device 100 and the ground 210.
[0052] The wearable electronic controller 202 is initially at the vertical position with
respect to ground 210. The wearable electronic Controller 202 is pre-fed with the distance
range for D1 which may vary vertically upwards and downwards upon wearing wearable
electronic Controller 202 keeping the distance D2 at a constant range of 0.10- 0.14 meters.
The chosen D2 range lies in the fact that the normal distance between hand 212 and chest lies
in this range only.
[0053] The defined D1 range can be in between 0.6-0.8 meters. During this range, no
forward or backward movement command is provided to the hovering device 100. If the D1
value goes beyond the defined range, appropriate signal is generated within wearable
electronic controller 202 and provided to the hovering device 100.
[0054] The defined D2 range can be in between 0.10- 0.14 meters. During this range,
no left or right turning command is provided to the hovering device 100. If the D2 value goes
beyond the defined range, appropriate signal such as left or right is generated within wearable
electronic controller 202 and provided to the hovering device 100.
Configuration of Hovering Device 100:
[0055] The signal reception unit 102 over hovering device 100 captures the signal
transmitted by the communication unit 212 of the wearable electronic controller 202 and
amplifies the LIFI signal. In order to amplify the LIFI signal, a small-sized convex mirror is
parallelly placed within the signal reception unit 102. The received LIFI signals are reflected
9

through parallel mirrors. LIFI signal is further scattered by the zero-point oscillations of the quantized fields, the light of frequency omega traveling normally to two parallel mirrors experiences the vacuum between them as a dispersive medium with refractive index (omega). Also, the hovering device contain a second IR LED 108 which is in direct communication with decoding unit. The decoding unit provides a command to generate an IR light using second IR LED 108, transmits towards wearable electronic controller 202 and continuous revert to the decoding unit about the distance between wearable electronic controller 202 and the hovering device 100. As per the distance between wearable electronic controller 202 and the hovering device 100, the decoding unit thus either turn on or turn of the microphone 104 followed by an audio message saving operation.
[0056] Upon amplification of the LIFI signal it is transferred to a decoding unit for
the appropriate task to be performed by the hovering device 100.
[0057] It is also defined in the decoding unit about the hovering process of the
hovering device 100 to be performed when the wearable electronic controller 202 detects a small motion of the hand 212 upon wearing. The decoding unit thus provides a command signal to the hovering device 100 to remain in the air. This command is executed as long as the distance between hovering device 100 and wearable electronic controller 202 is within bearable range of LIFI communication.
Instruction module:
[0058] In an embodiment, the apparatus 100 can include an instruction module in the
console of flexible wearable electronic controller 202 configured to generate LIFI signal
based on the distance data of the ground with respect to the wearable electronic controller
202.
[0059] The instructions module comprises mainly:
[0060] The distance data D1 and its possible variation within the range;
[0061] The distance data D2 and its possible variation within the range;
[0062] The forward movement signal to be generated as per the value of the D1 and
D2;
[0063] The backward movement signal to be generated as per the value of the D1 and
D2;
[0064] The left movement signal to be generated as per the value of the D1 and D2;
[0065] The right movement signal to be generated as per the value of the D1 and D2;
[0066] The voice recording process to be initiated as per the value of the D1 and D2;
10

[0067] The voice delivery process to be initiated upon pressing the button 208.
Method of using the invention:
[0068] Various cases will arrive when controlling the hovering device 100 by
wearable electronic controller 202 which are defined as below:
Case 1: - Generation of Forward Movement Signal (When D1<0.6):
[0069] This will indicate that wearable electronic controller 202 is near to the ground.
A Forward movement command as defined in the wearable electronic controller 202 is
generated and provided to the hovering device 100 using communication unit 212 to transfer
the LIFI signal to move forward. Signal reception unit 102 over hovering device 100 captures
the signal provided by wearable electronic controller 202, performs amplification and
provides to the decoding unit. As defined in the decoding unit about forward movement task
to be performed which is equivalent to the appropriate signal generation when the height of
the wearable electronic controller 202 is below defined range, the decoding unit hence
provides a command signal to the hovering device 100 to move in forward direction. The
forward movement command is executed as long as D1 is below the defined range (i.e. 0.6
meters). Also, forward movement is executed as long as the distance between hovering
device 100 and wearable electronic controller 202 is within bearable range of LIFI
communication.
Case 2: - Generation of Backward Movement Signal (When D1>0.8)
[0070] This will indicate that wearable electronic controller 202 is not near to the
ground. A backward movement command as defined in the wearable electronic controller 202 is generated and provided to the hovering device 100 using communication unit 212 to transfer the LIFI signal to move backward. Signal reception unit 102 over hovering device 100 captures the signal provided by wearable electronic controller 202, performs amplification and provides to the decoding unit. As defined in the decoding unit about backward movement task to be performed which is equivalent to the appropriate signal generation when the height of the wearable electronic controller 202 is above defined range, the decoding unit hence provides a command signal to the hovering device 100 to move in backward direction. The backward movement command is executed as long as D1 is above the defined range (i.e. 0.8 meters). Also, backward movement is executed as long as the
11

distance between hovering device 100 and wearable electronic controller 202 is within bearable range of LIFI communication.
Case 3: - Generation of Left Movement Signal (When D2<0.10)
[0071] This will indicate that wearable electronic controller 202 is now close to the
body chest. A Left movement command as defined in the console of wearable electronic
controller 202 is generated and provided to the hovering device 100 using communication
unit 212 to transfer the LIFI signal to move left. Signal reception unit 102 over hovering
device 100 captures the signal provided by wearable electronic controller 202, performs
amplification and provides to the decoding unit. As defined in the decoding unit about Left
movement task to be performed which is equivalent to the appropriate signal generation when
the position of the wearable electronic controller 202 is below defined range with respect to
the body chest, the decoding unit hence provides a command signal to the hovering device
100 to move in Left direction. The Left movement command is executed as long as D2 is
below the defined range (i.e. 0.10 meters). Also, Left movement is executed as long as the
distance between hovering device 100 and wearable electronic controller 202 is within
bearable range of LIFI communication.
Case 4: - Generation of Right Movement Signal (When D2>0.14):
[0072] This will indicate that wearable electronic controller 202 is now away from the
body chest. A Right movement command as defined in the wearable electronic controller 202
is generated and provided to the hovering device 100 using communication unit 212 to
transfer the LIFI signal to move Right. Signal reception unit 102 over hovering device 100
captures the signal provided by wearable electronic controller 202, performs amplification
and provides to the decoding unit. As defined in the decoding unit about Right movement
task to be performed which is equivalent to the appropriate signal generation when the
position of the wearable electronic controller 202 is above defined range with respect to the
body chest, the decoding unit hence provides a command signal to the hovering device 100 to
move in Right direction. The Right movement command is executed as long as D2 is above
the defined range (i.e. 0.14 meters). Also, Right movement is executed as long as the distance
between hovering device 100 and wearable electronic controller 202 is within bearable range
of LIFI communication.
12

Message recording Process:
[0073] The microphone 104 over hovering device remains ‘ON’ to accept the voice
and record the same until the distance between wearable electronic controller 202 and
hovering device 100 is within 4 meters. When the hovering device 100 is within 4 meters
from the wearable electronic controller 202, disabled person can speak which is
simultaneously recorded to the hovering device 100. For this, a second IR LED 108 is placed
over hovering device 100 which keeps reverting to the decoding unit about the distance
between hovering device 100 and wearable electronic controller 202. As soon as this
threshold distance is crossed by hovering device 100, the decoding unit provides a command
to turn off the microphone 104 and initiates message saving process so that no further voice
can be recorded. This provides a way of automatic recording and saving of the message to the
hovering device 100.
Message Delivery Process:
[0074] As soon as message is saved in the hovering device 100, disabled person can
provide a command using wearable electronic controller 202. A Forward movement
command as defined in the wearable electronic controller 202 is again generated and
provided to the hovering device 100 via communication unit 212 to move forward. Signal
reception unit 102 over hovering device 100 captures the signal transmitted by wearable
electronic controller 202, amplifies and transfers to the decoding unit. As defined in the
decoding unit about forward movement task to be performed which is equivalent to the
appropriate signal generation when the height of the wearable electronic controller 202 is
below defined range, the decoding unit hence provides a command signal to the hovering
device 100 to keep moving in forward direction. The forward movement command is
executed as long as D1 is below the defined range (i.e. 0.6 meters). Also, forward movement
is executed as long as the distance between hovering device 100 and wearable electronic
controller 202 is within bearable range of LIFI communication. If the person whom the
message is to be delivered is situated at a certain coordinate which involves left or right
direction movement of the hovering device 100, keeping the wearable electronic controller
202 below or above the defined range of D1 and D2 can navigate the hovering device 100 to
reach the concerned person. As soon as the hovering device reaches to the person concerned,
the disabled person can push the button 208 available over wearable electronic controller 202.
[0075] A message delivery command as defined in the console of wearable electronic
controller 202 is generated and provided to the hovering device 100 using communication
13

unit 212 to transmit the LIFI signal deliver the message. Signal reception unit 102 over hovering device 100 captures the signal provided by wearable electronic controller 202, amplifies and transfers to the decoding unit. As defined in the decoding unit about message delivery task to be performed when a push button 208 is pressed at wearable electronic controller 202, the decoding unit hence provides a command signal to the speaker 106 to deliver the saved message to the person. Message delivery command is executed as long as the distance between hovering device 100 and wearable electronic controller 202 is within bearable range of LIFI communication.
[0076] In an embodiment, the wearable electronic controller 202 is configured to be
worn on various sized hand/leg. Various hand or leg measurements for D1 and D2 can be
collected from various people and can be carefully placed in the console of wearable
electronic controller 202 such that any person in need can wear and operate the same.
[0077] In an embodiment, the control unit can include one or more processors or
controllers. Examples of controllers include, but are not limited to PIC® 16F877A
microcontroller, AVR® ATmega8 & ATmega16, Renesas® microcontroller and the like.
Examples of processor can include, but are not limited to, an Intel® Itanium® or Itanium 2
processor(s), or AMD® Opteron® or Athlon MP® processor(s), Motorola® lines of
processors, FortiSOC™ system on a chip processors or other future processors.
[0078] Those skilled in the relevant art will appreciate the design of system to control
the hovering device by a disabled person for conveying his/her message. A further modification can be done such as a setup for faster signal processing can be used in the hovering device 100 as well as improving the signal transmission of LIFI based communication.
[0079] Although the proposed system has been elaborated as above to include all the
main parts, it is completely possible that actual implementations may include only a part of the proposed modules/engines or a combination of those or a division of those in various combinations across multiple devices that can be operatively coupled with each other, including in the cloud. Further the modules/engines can be configured in any sequence to achieve objectives elaborated. Also, it can be appreciated that proposed system can be configured in a computing device or across a plurality of computing devices operatively connected with each other, wherein the computing devices can be any of a computer, a laptop, a smart phone, an Internet enabled mobile device and the like. All such modifications and embodiments are completely within the scope of the present disclosure.
