Abstract - Semi-paralysis is a condition characterized by muscle weakness and diminished motor function, where individuals retain some sensation and partial control over the affected muscles. The objective of this project is to developadevice thatisboth user-friendlyandcost-effective. For patients with semi-paralysis who struggle to express their needs, we have developed a system that facilitates communication through gestures. This innovative solution enables patients to effectively convey their messages to caregivers or designated individuals, enhancing their ability to interact and receive timely assistance. The system primarily operates using Internet of Things (IoT) technology.

1.INTRODUCTION
Partial paralysis, also known as paresis, is a condition marked by muscle weakness and impaired movement, where individuals retain a certain degree of control over the affected muscles. Unlike complete paralysis, which results in total loss of muscle function, paresis allows for partial movement and strength, though the extent of control varies by individual. This condition can significantly impact daily activities and mobility, depending on the severity and location of the muscle weakness.
Causes of semi-paralysis include nerve damage, trauma, stroke, illness, and various neurological diseases. The severity of paralysis depends on the extent of muscle function loss and can result in a range of symptoms, such as:
● Muscleweakness
● Impairedmovement
● Lossofsensation
● Numbness
Patients affected by semi-paralysis often require assistance from caregivers to perform routine tasks. Paralysiscanpresentinseveralforms,including:
● Hemiparesis(weaknessononesideofthebody)
● Monoplegia(affectingasinglelimb)
● Diplegia(bothsidesofthebody,usuallylegs)
● Paraplegia,Quadriparesis,and
● FacialWeakness
Our project focuses specifically on Hemiparesis, Monoplegia,andFacialWeakness.
According to a survey conducted by the Christopher and Dana Reeve Foundation, 1 in every 50 individuals is affected by some form of paralysis. In response to this growingconcern,wehavedevelopedParaRing,awearable ringequippedtodetectmotion.Whenspecificgesturesor movements are detected, the ring transmits the corresponding data to a mobile application.

3. Working Principle
The ParaRing works by continuously tracking finger movements using a 3-axis accelerometer (ADXL345) placed within a wearable ring. It interprets motion along theXandYaxestorecognizespecificgesturesmadebythe patientandcommunicatesthoseasalertsusingIoT.
The system monitors the ring’s orientation and detects movementthresholdsthatcorrespondtobasicneeds:
● A leftward flick (positive X-axis movement) is interpretedasarequestforwater
● A rightward flick (negative X-axis movement) signalsthepatientishungry
● An upward hand movement (positive Y-axis value)isinterpretedasanemergencyhelprequest
Onceagestureisdetected,theringsendsanalertsignalto a Firebase Realtime Database. Each type of gesture is loggedintoaseparatecategory:
● Waterrequest→storedasxlcount
● Hungerrequest→storedasxrcount
● Emergency→storedasycount
These values are instantly updated in the Firebase databaseandcanbeaccessedviaamobileapplicationbya caregiver. This ensures real-time response and improves thequalityofassistanceprovidedtothepatient.
After a caregiverattendsto thepatient,thesystemallows the alert to be reset remotely via the mobile app. To do this,theappsends a special value(the number 92)to the alerttagfieldinFirebase.
Whentheringreceivesthissignal,itautomatically:
● Resetsthealerttagbackto0
● Clears all previous gesture values (water, hunger, emergency)
● Preparesthesystemtodetectnewalerts
Thisensures:
● Thesystemavoidsrepeatingthesamealert
● Caregiversreceiveonlynew,relevantinformation
● The device remains ready for continuous use without manualreset

8. Future Scope
The ParaRing system is designed to empower individuals withpartialparalysisbyallowingthemtorequesthelpfor essential needs such as food, water, and mobility
assistance.Byimprovingpatientindependence,it reduces the burden on caregivers and enhances the overall caregivingexperience.
The device is cost-effective, lightweight, and portable, making it suitable for real-world deployment. As future engineers, it is our responsibility to develop and advance suchtechnologiesto better support andimprove the lives ofindividualslivingwithpartialparalysis.
