The introduction paragraph of the Guide buddy proposal (including 5 parts: Problem, Evidence/Prevalence of the problem, Target Group Affected, Why the issue deserve attention, Project Purpose): "Visual impairment (VI) refers to different degrees of sight loss which cannot be corrected by glasses, surgery, or other medical methods (American Optometric Association, 2010) and therefore our target group relies on assistive devices (The problem).

VI is increasingly prevalent in Hong Kong with around 199.600 people with visual impairment, accounting for 2.7% of the total population (Census and Statistics Department, 2021)(Evidence/prevalence of the problem). Vision loss is strongly associated with advancing age, with a majority of the VI population being over the age of 60. It is predicted that the figure will continue to rise considering the ageing population in the city (Group Affected).

Numerous studies have established a strong correlation between vision impairment and depression (Demmin & Silverstein, 2020), and our personal volunteering experience has shown us the reality of how the loss of sight is a highly distressing, overwhelming and life-altering event. Supporting this demographic is vital for ensuring the wellbeing of the visually impaired population, (Why this deserves attention) and so our vision is to empower the visually impaired through Guide Buddy, an advanced robotic guide dog with animal-like appearance and humanistic design. Our prototype design aims to enhance the accessibility of visually impaired people through GPS, ariel photography, map data and a real-time database, and to support their mental health by offering personalised settings and realistic companionship (The vision/purpose)."
The points of my project waveguard :"OBJECTIVES
Users will be able to

monitor the motions and different vital signs of them/ their elderly family who live alone remotely through the real-time millimeter wave (mmWave) based system and artificial intelligence (AI) algorithms
gain timely medical support by notifying the medical personnel/their family through the wireless communication speaker system
PROBLEMS/NEEDS/OPPORTUNITIES
Aging Population: Demographics shift towards more elderly individuals, over 1 million of the population are aged 65 or above in Hong Kong.
Safety Concerns: The Unintentional Injury Survey 2018 conducted by the Department of Health (DH) showed that fall was the most common type of unintentional injury, accounting for 39.4% of all injury episodes that occurred over a 12-month period. Falls and accidents pose serious risks to the solitary elderly as they may not be discovered very soon, necessitating early detection and intervention.
Healthcare Challenges: About 70% of the elderly in Hong Kong are suffering from chronic diseases, most commonly diabetes and hypertension. Timely health condition monitoring and treatment are needed, especially for the solitary elderly.
EXISTING SOLUTIONS
Vision-based detection systems, e.g. video cameras, depth cameras, and thermal cameras: Have privacy issues and low detection accuracy in low light, clothing cover environments.
Non-vision-based sensors, e.g. acoustic-based systems, vibration-based systems, infrared-based systems and radar-based systems: Limited by the effect caused by environmental noise.
Wearable devices, e.g., smartwatches and IMU devices: Inconvenient and unacceptable because the elderly may forget to wear the device.
KEY FEATURES AND FUNCTIONS
A mmWave-based monitoring system that can detect different motions of the elderly, e.g. walking, standing, falling, sitting down, picking, etc., and different vital signs, e.g. respiration and heart rate, by leveraging mmWave sensing and machine learning technology.
Combined with a wireless communication-based system and speaker that directly contacts and communicates with the medical personnel and the elderly’s family when detecting accident or emergency situations.
This system can protect the privacy of the user since the mmWave will not capture any image or video; the detection accuracy is invariant to light conditions, clothing cover environments, temperature changes and environmental noise, and it is convenient because the user do not have to wear any device.
A program (software application) for the hospital and elderly’s family to monitor the elderly’s health situation consistently in real time.

Using the structure of Guide Buddy's project proposal's introduction (including and highlighting the 5 parts: Problem, Evidence/Prevalence of the problem, Target Group Affected, Why the issue deserve attention, Project Purpose) and my points(it is not necessary to use all of my points), write an introduction paragraph of Waveguard for about 200 words.
