A SMART PRAYER RUG AND A METHOD OF OPERATING THE SAME

TECHNICAL FIELD

Embodiments of the present invention relate to a prayer rug, and more

particularly, to a smart prayer rug and a method of operating the same, which

notifies plurality of users, primarily elderly, inexperienced children who just started

learning to pray and those having cognitive and memory weaknesses, who might

forget how many raka’ah have been performed at the time of solah (prayer). The

smart prayer rug notifies the number of raka’ah performed while preserving the

concentration and perfection of the solah.

BACKGROUND ART

Performing solah (prayer) five times a day is the second pillar of Islam,

compulsory to all Muslims. Every routine in a solah should be implemented so that

the solah is performed perfectly and with regard to Islamic principles. However,

while performing solah, there is probability to forget how many cycles called

raka’ah have been completed, since each of the five solah has different raka’ah.

The difficulty of remembering the raka’ah sequences could be found mainly in

inexperienced children who are not acquainted with the method of praying, the

elderly and those having cognitive and memory weakness, such as mild (early –

stage) Alzheimer, dementia and mild amnesia. Moreover, since the person must

repeat the raka’ah a plurality of times, and sometimes recites long verse surahs

from the Quran during first two raka’ah, it becomes a shortcoming for the person

to remember which raka’ah is being performed. Under these circumstances, once

forgotten, the person must go back and perform additional raka’ah to ensure that

at least exact number of raka’ah has been performed in a solah. This situation

5

may affect the concentration while performing the solah. Thus, a user friendly

device is needed whereby Muslims become proficient at the daily raka’ah

sequences in prayer, as well as the concentration in solah.

There have been number of solutions provided for efficiently and

precisely performing the solah and few of them are discussed below:

US20110294100A1 describes an elongate prayer mat having a first end

and a second end. The prayer mat comprises a first tactile sensor disposed

proximate to the first end, a second tactile sensor disposed proximate to the

second end, a third tactile sensor disposed proximate to the second tactile sensor

and between the second tactile sensor and the first one, a fourth tactile sensor

disposed to the right of the third tactile sensor, proximate to the second tactile

sensor and between the second tactile sensor and the first tactile sensor. Also, a

microprocessor for receiving electrical signals from the tactile sensors and for

displaying the progress of prayer steps on a display device.

US8647122B2 discloses an interactive prayer system which includes a

pad that is adapted to be repeatedly stepped upon by a user, a communication

means for communicating touch event data and proximity event data to a

computer and a computer program executing on the computer, which displays the

scripture to the user during prayer, and a notification means embedded in the pad

for notifying the user.

WO2009144689A1 describes a digital tally counter finger ring which can

be put on a hand finger or placed on the ground closed to the user’s head at the

5

time of use, having a count or set button as a switch to do counting operation

which is useful for religious activities such as counting for data collections or

inventories in the day and night time. It also has an IRP (Infrared Proximity)

sensor or close range detection sensor comprising an IR Transmitter and an IR

Transmitter and an IR Receiver which is useful for counting number of

prostrations in Muslim daily prayers or other similar activities, and has an On or

Off button.

The aforesaid documents and other similar solutions may strive to

provide solutions for performing efficient solah, however, they still have a number

of limitations and shortcomings such as, but not limited to, the technologies to

count and display the number of raka’ah while performing solah is impracticable

and may be distracting to a user since focus will be possibly diverted from the

solah being performed to the particular placement of the user’s forehead on the

prayer rug. It is also inconvenient to use, since the existing device worked only if

the position of the user’s forehead is precisely placed on the switch in order to

update the number of raka’ah performed. In addition, it may affect the

concentration while performing solah, since the number of raka’ah performed is

displayed all the time throughout the prayer.

Accordingly, there remains a need in the prior art to have an improved

technology, which overcomes the aforesaid problem and shortcomings. In

particular, there remains a need in the art for a smart prayer rug, which assist a

user to perform solah precisely and without any distraction. Further, the smart

prayer rug is easy to use and does not require any specific skills to operate.

(102) are placed on the foot region (108), the knee region (110) and the head

region (112).


switch (106) is having the plurality of LED indicators (114). The plurality of LED

indicators (114) used to count the number of sudjood, in order to configure the

complete number of raka’ah performed by the user (101).

At step 206, the plurality of sensors (102) are triggered by the user (101)

by placing his or her foot on the foot region (108). In other words, the moment the

user (101) places his or her foot on the foot region (108) of the smart prayer rug

(100), the plurality of sensors (102) at the foot region (108) are activated.

At step 208, the number of raka’ah performed by the user (101) is

counted by the power switch (106). The Step 208 is elaborated in Figure 4 below:

At step 2082, as shown in Figure 4, a first indicator of the plurality of LED

indicators (114) is switched on as and when the user (101) triggers the plurality of

sensors (102) placed at the knee region (110) and the head region (112) for the

first time.

At step 2084, a second indicator of the plurality of LED indicators (114) is

switched on as and when the user (101) triggers the plurality of sensors (102)

placed at the knee region (110) and the head region (112) for the second time.

At step 2086, the plurality of LED indicators (114) record two times of

sudjood complete by the user (101). Further, at step 2088, the power switch

detect that plurality of sensors (102).

At step 20810, the first complete raka’ah is recorded. One complete

raka’ah is recorded once the plurality of sensors (102) placed at the knee region

(110) and the head region (112) are deactivated by the user (101). Preferably, the

plurality of sensors (102) placed at the knee region (110) and the head region

(112) are deactivated as and when the user (101) stands up to begin a next

raka’ah.

At step 20812, the number of raka’ah completed by the user (101) are

updated by the power switch (106).


switch (106) is configured to update the number of raka’ah performed by the user

(101) and after deactivation of the plurality of sensors (102) at the knee region

(110) and the head region (112). Also, the power switch (106) is configured to

provide information regarding the number of raka’ah performed by the user (101)

to the display device (104).

At step 210, as shown in Figure 3, the number of raka’ah performed by

the user (101) are displayed on the display device (104). The step 210 is

elaborated in Figure 5 below:

As step 2102, as shown in Figure 5, the plurality of sensors (102) are

triggered by the user (101). The user (101) triggers the plurality of sensors (102)

5

10

15

20

25

18

placed at the knee region (110) and the head region (112). Further, the triggered

plurality of sensors (102) switch on the first and the second indicator of the

plurality of LED indicators (114).

As step 2104, information regarding the number of raka’ah performed by

the user (101) is gathered from the power switch (106).

In other words, switching on the first and the second indicator of the

plurality of LED indicators (114) at step 2102, confirms the completion of two

sudjoods. Further, one complete raka’ah is recorded in the microcontroller (116) of

the power switch (106) after deactivation of the plurality of sensors (102) at the

knee region (110) and the head region (112). Then, the count of number of

raka’ah performed by the user (101) has been updated.

At step 2106, the number of raka’ah performed by the user (101) are

displayed on the display device (104) for a predetermined time. In accordance

with an embodiment of the present invention, the user (101) triggers the display

device (104) to display the number of raka’ah completed by him or her. Preferably,

the user (101) can trigger the display device (104) in the following two conditions:

i. In case the user (101) is standing in an upright position, he or she

should uplift his or her right foot a little in order to trigger the display

device (104) to display the number of raka’ah completed by him or her. In

this scenario, it is the plurality of sensors (102) provided on the foot

region (108) which provides information to the power switch (106).

5

10

15

20

25

19

ii. In case the user (101) rises to a sitting position with head bowed from

the first sudjood, he or she should uplift his or her right knee a little in

order to trigger the display device (104) to display the number of raka’ah

completed by him or her. In this scenario, it is the plurality of sensors

(102) provided on the knee region (110) which provides information to

the power switch (106).


predetermined time is in the range of, but not limited to, 2-15 seconds. The

display device (104) is the, but not limited to, 7-segment LED display. Further,

maximum number of raka’ah that are displayed on the, but not limited to, 7-

segment LED display is 4.

At step 212, as shown in Figure 3, the steps 206 to 210 are repeated if

more raka’ah have to be performed. Further, if no more raka’ah has to be

performed, the method of operating the smart prayer rug (100) comes to an end.

The above-mentioned smart prayer rug and the method of operating the

same overcome the problems and shortcomings of the existing technologies and

provide a number of advantages over them. The unique feature of the smart

prayer rug is focusing on the raka’ah notification to the user, who performs the

solah but forgets the number of raka’ah he or she already completed. Further, the

number of raka’ah will be displayed on the display device only when the user

intends to know, hence preserving the focus or khusyuk in solah and the number

of raka’ah has been completed. The proposed prayer rug can be used by the

users who experience cognitive and memory weakness diseases such as mild

5

10

15

20

25

20
