I am writing a project proposal for seed funding for an engineering project.The project proposal should include the part Project Summary, Introduction, Goal and Objectives, Current Situation, Product Overview, Technical Description, Impact, Project Team, Schedule, Budget, Conclusion and References. Specifically, I am writing the Technical Description part. My project named "Waveguard", and my project outline is :
"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.

Product Overview
Our project team has meticulously designed the prototype to closely resemble its real-life counterpart, while incorporating key features that make it an advanced robotic companion.
Unobtrusive Physical Presence
To strike a balance between being unobtrusive and providing a reassuring physical presence, the design and dimensions of the prototype are comparable to the Labrador breed, allowing Guide Buddy to move comfortably in various environments while not being obtrusive.
•	Height: Approximately 24 inches (61 cm) at the shoulder.
•	Length: Approximately 36 inches (91 cm) from the nose to the base of the tail.
•	Width: Approximately 12 inches (30 cm) across the body.
The specific size and dimension can be adjusted based on ergonomic considerations and user feedback during the Conceptualisation and Design stage.
Realistic Exterior Design
To achieve a lifelike texture, the exterior of the prototype features a combination of synthetic materials, specialised coatings, and synthetic fur. Thermoelectric and Peltier devices [15] will be used to maintain a warm temperature just like a real dog. We will also leverage the soft robotic shell design introduced by Dr. Osawa in her 2021 paper [16]. With warm body temperature, a soft robotic shell and a synthetic fur, our prototype will offer realistic companionship for the visually impaired.


Sturdy and Lightweight Construction
To achieve a desired balance of sturdiness, lightweight construction, and portability, high-quality polymers and composite materials will be utilised in the construction. Two main materials will be tested during the prototype design stage:
1.	Carbon Fibiber-Reinforced Polymer (CFRP): CFRP offers exceptional mechanical properties, including high tensile strength and stiffness, while remaining significantly lighter than traditional materials like steel or aluminum [17].
2.	Glass Fiber-Reinforced Polymer (GFRP): GFRP offers good strength, stiffness, and impact resistance while maintaining a lightweight profile. GFRP is commonly used in various industries, including aerospace and automotive, due to its favorable mechanical properties [18].
 
Seamless Communication and Interaction
To facilitate communication and interaction, the protoype is equipped with a range of sensors, cameras, and speakers discreetly integrated into its eyes and onto its ears respectively. These components allow the prototype to perceive its environment, recognise user commands, and provide audio feedback or responses when necessary. Speakers and audio devices are seamlessly connected via Bluetooth, providing wireless audio communication. Users have the option to use the speakers or connect earphones.
Accessible and User-friendly Features
To ensure easy set up and setting adjustment, the device will incorporate the following accessibility features and user-friendly interfaces:
1.	Text-to-Speech and Audio Prompts: To provide audible instructions and prompts to the visually impaired during the setup and adjustment process, text-to-speech capabilities will be integrated. Guide Buddy will provide clear and structured auditory feedback to inform users about the progress, completion and any errors or issues encountered. This feedback will be designed to be easily distinguishable and understandable through speech patterns, tones, or sound cues.
2.	Voice Commands: To enable users to give verbal instructions to set up the device and make personalized adjustments without relying on visual feedback, voice recognition functionality will be incorporated.
3.	Tactile Markings and Buttons: To facilitate users to locate and interact with the necessary controls, Guide Buddy will be designed with tactile markings and embossed symbols for easy identification by touch.
4.	Companion Device: To allow visually impaired users to control and adjust personalised settings using a screen reader or other accessibility features available on their smartphones or compatible devices, Guide Buddy will have a companion mobile application with an accessible user interface.
 
Technical Description
Accurate Outdoor Navigation
With GPS, robotic guide dogs can track their location, measure the distance between destinations and find out the shortest path (Terrier & Schutz, 2005). Map data is also essential for accurate GPS Navigation and can be collected by aerial photography (Marzolff & Poesen, 2009). Aerial photography could provide higher resolution, and so with good-quality map data and GPS, robotic guide dogs can provide accurate outdoor navigation. A real-time database will be built in to provide real-time information to users such as traffic density, and road blocks.
Siri-integrated Communication
The project team will focus on (1) expanding answer database, and (2) incorporating AI voice generation. We will collaborate with Hong Kong Blind Union to develop a response database that addresses the most common problems, inquires and scenarios. In addition to an expanded answer database, the innovative approach of AI voice generation enables more natural and engaging interactions.
Personalised Settings
Using Artificial Intelligence, settings will be customised based on the analysis of the users’ behaviors and preferences. Default settings will be suggested but all settings can be further adjusted manually.
1.	Personal Profile: To enhance the guide dog's ability to provide tailored support, the personal profile of the user will be processed by AI and machine learning.
2.	Training Mode: To build confidence and reinforce skills, users will be able to customise simulated training sessions with the guide dog.
3.	Obstacle Sensitivity and Environmental Adaptation: To adapt to personal preferences, safety concerns and environmental variations, users will be able to adjust the sensitivity of obstacle detection and avoidance.
4.	Route Preferences: To ensure efficiency and accessibility, users can set preferences for route selection.
5.	Footstep tracer: To ensure safety, users can control the pace of Guide Buddy according to their own pace through the velocity tracking controller.
Day-long Operation
Lithium-ion (Li-ion) batteries will be used due to their high energy density, relatively long cycle life, and lightweight characteristics. The following energy-efficient components, power-saving modes, and energy harvesting techniques will also be integrated into the design:
 
1.	Energy-Efficient Components: Guide Buddy can utilize low-power sensors, such as proximity sensors or motion sensors, that consume minimal energy while providing accurate data for obstacle detection and navigation.
2.	Power-Saving Modes: Guide Buddy can incorporate power-saving modes that automatically activate during periods of inactivity. During this mode, non-essential functions can be temporarily disabled or put on standby.
3.	Energy Harvesting: Solar panels can be integrated into the device's body or accessories, allowing it to recharge its battery using sunlight. Kinetic energy harvesting mechanisms, such as generating electricity from the movement of the device or the user's interactions, can also be implemented to capture and convert energy into usable power.
