INTRODUCTION According to incomplete statistics of CED term who are teaching sign language in Ho Chi Minh City University of Education [1] , 6.9 million deaf and dumb people in Vietnam have difficulty in communicating with normal people Therefore, they are almost isolated from general activities such as are study, physical and mental development The language that is used for deaf and dumb people as know as Sign Language As similar as spoken languages Sign Language emerge and evolve naturally within hearing-impaired communities Within each country or region wherever hearing-impaired communities exist sign languages develop independently from the spoken language of the region Each sign language has its own grammar and rules with a common property that they are all visually perceived Sign language recognition (SLR) [3] is a multidisciplinary research area involving pattern recognition, computer vision, natural language processing and linguistics It is a multifaceted problem not only because of the complexity of the visual analysis of hand gestures but also due to the highly multimodal nature of sign languages Although sign languages are well-structured languages with a phonology, morphology, syntax and grammar, they are different from spoken languages: The structure of a spoken language makes use of words sequentially, whereas a sign language makes use of several body movements in parallel The linguistic characteristics of sign language are different from those of spoken languages due to the existence of several components affecting the context, such as the use of facial expressions and head movements in addition to the hand movements VIETNAM SIGN LANGUAGE (VSL) 1.1 The concept of sign language A sign language (also signed language or simply signing) is a language which instead of acoustically conveyed sound patterns uses manual communication and body language to convey meaning This can involve simultaneously combining hand shapes orientation and movement of the hands, arms or body and facial expressions to fluidly express a speaker's thoughts They share many similarities with spoken languages (sometimes called "oral languages" which depend primarily on sound) which is why linguists consider both to be natural languages, but there are also some significant differences between signed and spoken languages [2] In fact, we are using it in our life What will happen if you close your eyes and just talk only? Certainly, that conversation will be very boring In communication we convey many things via gestures 1.2 Characteristics  Region differences For example: To describe the pink, in Hanoi they rub their hands in their cheek but in Saigon they put their hands on their lips  Reductive Sign Language focuses on how to express easily and simply to understand For example: Spoken language: “ Anh Có Khỏe Không ?” Vietnam Sign Language: “ Khỏe Không ?” That is a difficulty in recognition and translation We don’t know who speaker is talking about  Vocabulary VSL vocabulary is very small In a community used a common sign language, there are about 500 words [5] and most of them are verbs The following is alphabet used in Vietnam and countries where use Latin alphabet: Figure 1.The manual Alphabet  Grammar As we mention above, VSL has no fixed grammatical structure The following is frequent structures:  Positive  Subject + Verb + Predicate (+)  Negative  Subject + Verb+ Negative Word (-)  Question  Subject + Verb + Question Word (?) TEAM CONTRIBUTION: With the purpose of dividing the work appropriately and helping every member of the group understand all the aspects of the thesis, we created a chance for every member to participate in almost all parts of the thesis The specific contributions of the members are listed as below: Lê Hà Bảo Ngọc: studied theories related to the thesis and write code for MCU Dương Thanh Mỹ: studied and design schematic, make and test main circuit Võ Thành Văn: studied theories about the GSM, writing code for ModuleSim908 Timeline: As the registration, on on May, June and July, we studied theories and try to make Quadrotor But after all, we found that this project doesn’t have practical applications and Quadrotor’s components are too expensive with us So we decided to change project and started with Body Temperature and Heart-rate Monitoring System on August 3/8: Start the thesis 20/8: Finish schematic 1/9: Make and test circuit Writing code 25/9: Finish circuit, write thesis and prepare for presentation August September Research Coding Report 351 INTRODUCTION With the quick development of science, the applications of electronics technical to medicine is more popular In health, body temperature and heart rate are important features should be monitored But, in Vietnamese, the overload in hospital make it hard for the doctor to continuously update these features Our purpose is to implement a Body Temperature and Heart rate Monitoring system using TI MCUs Beside the system at place, it also have module to communicate through GSM to warn doctor if there are something wrong We choose this project because of its interesting and technical nature as well as highly applicability 352 THEORETICAL BASIC Infrared and Heartrate: Infrared (IR) light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometres (nm) to mm This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz Most of the thermal radiation emitted by objects near room temperature is infrared Infrared light is emitted or absorbed by molecules when they change their rotationalvibrational movements Infrared energy elicits vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry Infrared spectroscopy examines absorption and transmission of photons in the infrared energy range Heart rate refers to the speed of the heartbeat, specifically the number of heartbeats per unit of time The heart rate is typically expressed as beat per minutes (bpm) The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excrete carbondioxide The normal human heart rate ranges from 60–100 bpm When the heart rate is not regular in a regular pattern, this is referred to as an arrhythmya These abnormalities of heart rate sometimes, but not always, indicate disease 353 GMS Module: SIM908 module is a complete Quad-Band GSM/GPRS module which combines GPS technology for satellite navigation The compact design which integrated GPRS and GPS in a SMT package will significantly save both time and costs for customers to develop GPS enabled applications 354 HARDWARE DESIGN: SENSORS ( temperature, infrared) MCU Module GSM DISPLAY ( modulesim908) lcd 16X2 Hardware of this device can be divided into parts: Central Processing Sensors Display at place Modulesim908 Central Processing: The main task of this unit is read values from the sensors The analog signals at receiver sensor will be converted into digital signals by the ADC module (Analog to Digital Converter) After that, sensors’s values will be display on LCD 16X2 If the values is over threshold, MCU will process it and send an SMS to their own doctor So, we choose MSP430G2553 as the main processing control unit for our device 355 MSP430G2553 with these advancetages: • Low Supply-Voltage Range: 1.8 V to 3.6 V • Ultra-Low Power Consumption • Ultra-Fast Wake-Up From Standby Mode in Less Than µs • Basic Clock Module Configurations – Internal Frequencies up to 16 MHz With Four Calibrated Frequency (LF) Oscillator – 32-kHz Crystal – External Digital Clock Source • Two 16-Bit Timer_A With Three Capture/Compare Registers • Up to 24 Touch-Sense-Enabled I/O Pins • On-Chip Comparator for Analog Signal Compare Function or Slope Analog-to-Digital (A/D) Conversion • 10-Bit 200-ksps Analog-to-Digital (A/D) Converter With Internal Reference, Sample-andHold, and Autoscan 356 Sensors: 2.1 Temperature sensor: LM35 Our project will be reading data from the body temperature One data we want to read is external temperature I need a temperature sensor with a big range as at 30km up you can be at 40ºC So first I tried using the LM35, an analog temperature sensor, with a nice range from -55 to 150ºC and a linear output of 10mV per 1ºC So to read the temperature from the LM35, I need to read the value from one ADC channel and use a simple calculation to get the temperature, as the sensor outputs 10mV per ºC, you just need to multiply the ADC output value for the VCC (5V) and for 100, and then divide it for 1024 (10-bit ADC resolution) 2.2 Infrared sensor to calculate Heartrate: Heart rate measurement indicates the soundness of the human cardiovascular system This project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood It consists of an infrared LED that transmits an IR signal through the fingertip of the subject, a part of which is reflected by the blood cells The reflected signal is detected by a photo diode sensor The changing blood volume with heartbeat results in a train of pulses at the output of the photo diode, the magnitude of which is too small to be detected directly by a microcontroller Therefore, a two-stage high gain, active low pass filter is designed using two Operational Amplifiers (OpAmps) to filter and amplify the signal to appropriate voltage level so that the pulses can be counted by a microcontroller 357 Modulesim 908: If there are any problems, modulesim908 will send a SMS to the doctor And when doctor or victim’s family want to know victim’s information, they can send a SMS and get it 358 SOFTWARE DESIGN: MAIN: BEGIN Set Basic Clock Timer Interrupt (Continuous Mode) Port1 Interrupt (P1.1) Have doctor’s F required message?
