According to argument 1, the Stick Body has a GPS sensor and three ultrasonic sensors embedded in it. 4. 4. A GPS sensor sends the blind man's current location to the guardian's phone via a short message in real time, according to claims 1 and 2. 5. To detect obstacles, three ultrasonic sensors are used from the front, left, and right directions, according to claims 1 and 2. 6. According to argument 2, the pen is alerted to the existence of obstacles by a buzzer. 7. Voice guidance can be obtained from a voice sensor, according to claim 2. 8. According to claim 2, the Respiratory sensor is used to detect the blind respiratory rate. , Description:BRIEF DESCRIPTION OF THE INVENTION
A smart pen and a smart walking stick are included in this invention. The blind can communicate with a walking stick through a buzzer attached to a smart pen. Blind people may carry a smart pen in their pocket to receive warning messages about obstacles in their path or whether their stick is missing. Sensors on the walking stick gather information about position and obstacles in the blind's left, right, and front.
Ultrasonic sensor
An ultrasonic sensor is a type of sensor that uses sound waves to detect an object. It works on the same principle as radar or sonar, which produces and absorbs high-frequency sound waves. Sensors measure the distance of an object by measuring the time it takes for the echo signal to be received after transmitting the signals and receiving the echo signals back. On the stick, three ultrasonic sensors are used from the front, left, and right directions. After that, obstacles are detected by measuring the time it takes for an ultrasonic wave to return from and direction after being reflected by an obstacle. The clear path is the direction from which the wave returns in the shortest amount of time. This component receives data from sensors and uses it to aid in intelligent decision-making by using AI algorithm.
Respiratory Sensors
Respiratory rate is a critical metric in a variety of health, home care, work, and sports applications. Pen embedded with respiration sensor which is used near to chest of blind people . One of the key vital signs, along with blood pressure, pulse, and temperature, is respiratory rate, which is the number of breaths someone takes per minute. At this rate of breathing, carbon dioxide leaves the lungs at the same rate as it enters. Breathing rates of less than 12 or more than 20 may indicate a problem with normal breathing. Respiration status can aid in the detection of apnea symptoms and provide early notice, diagnosis, and treatment.
Voice Sensor
A computer or program's ability to accept and interpret dictation or understand and carry out spoken commands is known as voice or speaker recognition. With the advent of AI and intelligent assistants, voice recognition has gained popularity and use. Voice recognition systems enable blind to interact with technology simply by speaking to it, enabling hands-free requests, reminders and other simple tasks. is a module that senses sound waves and converts them to electrical signals based on their strength.
It functions in the same way as our ears do, with a diaphragm that transforms vibrations into signals. A sound sensor, on the other hand, is made up of an in-built capacitive microphone, a peak detector, and a sound-sensitive amplifier (LM386, LM393, etc.). It is possible for the sensor to operate with these components:
• Sound waves travel through the molecules of air.
• The diaphragm in the microphone vibrates as a result of such sound waves, causing capacitance to shift.
• The shift in capacitance is then amplified and digitalized for sound strength processing.
GPS sensor
GPS sensors are antenna-equipped receivers that use a satellite-based navigation system that relies on a network of 24 satellites orbiting the earth to provide location, velocity, and timing data. It receives signals from satellites orbiting in the Global Positioning System (GPS) and uses them to measure location and velocity. For precise timing measurements, the GPS16X-HVS also provides an extremely accurate one-pulse-per-second (PPS) recording. It captures the location of blind on every second and the same can send to guardian mobile as a text message.
Buzzer
The buzzer is a small but effective part for adding sound to this innovation. It has a small and lightweight 2-pin structure that makes it easy to use on a pen. It will alert blind people about obstacles and misplaced sticks. By using the buzzer's beep tone, the blind may become conscious of these.
