Repeatedly searching online to identify the subject can be a lengthy and tedious task, and this is the problem we seek to address. Our solution is meant to enlighten our user of unknown plants, animals, or objects in any setting they are observing. # Solution Our project idea stems from the surge of AR prototype glasses being introduced over the past year. We are planning to create our own glasses but in contrast to those on the market, ours will focus on the audio experience of the user. These glasses will have the explicit capability of capturing images of objects and relaying this information to an application that will process these images in the backend. The application will then send an explanation of the object back to an audio device on the glasses (either a speaker or bone-conducting device). The glasses will essentially work as a digital tour guide, with the explanation of the object being auditory rather than visual. The use case we have decided to tackle is a botanical tour guide, but the purpose is to create a platform that other applications can utilize for their objectives. The subsystems we have broken down the device into are power, peripheral, communication, physical, and application. They are divided such that each subsystem has a designated purpose working towards the goal of full functionality. # Solution Components ## Power System The power system consists of the battery powering the device and the supporting charging circuit to replenish the battery once out of power. Some candidates for batteries are PCIFR18650-1500 from ZEUS Battery and ASR00011 from TinyCircuits. ## Peripheral System The peripheral system focuses on the aspects of the glasses that interact with the outside world. This includes the camera, microphone, speaker, and interact button. These external components will interface with the microcontroller, provide crucial information to the application, and play audio to the user. For the moment we have the following components for each peripheral: Camera: ESP32-CAM (Comes with development board and camera) Microphone: CMA-4544PF-W Speaker: ADS01008MR-LW100-R Interact Button: B3U-1100P ## Communication System The communication system consists of a microcontroller and Bluetooth Low Energy interface. This subsystem should create an interface that can be used by applications connected through Bluetooth. This interface allows for all the sensor data to be collected, processed, and sent to the application when requested. The component we plan to use for this system is the ESP32-WROOM-DA-N8 which contains an ESP32 microcontroller with a built-in PCB antenna for Bluetooth. ## Physical System The physical system consists of the glass frame design and the mounting system for the PCB and hardware components. The frame design will be 3D printed. The goal would be to use premeasured plastic mounting points and screws to mount all components within the hollow frame. ## Application System The application system consists of image processing, audio transfer, and user interface. The image will be processed, the plant will be identified, and then have audio transferred back to the speaker in the peripheral system. We will develop this application for iOS and interact with the glasses via Bluetooth. # Criterion For Success The following goals are fundamental to the success of our project: - Successful User Flow - The user should be able to look at a plant, press the interact button, and then wait for the system to return the audio of the plant description. - Accuracy - The final prototype should be able to correctly identify plants 75% of the time. - Strong Bluetooth Connection - There should be an uninterrupted Bluetooth connection between the glasses and the mobile - device. Additionally, the glasses should be fully operational within a 15-foot range of the mobile device. The goals below are considered reach goals, and if not accomplished would not hinder the success of our project: - Bone Conduction Audio - An alternative way of relaying the audio to the user that involves transmitting sound vibrations through the bones. - Adjustable Audio Volume Level - Within the application system the user will be able to adjust the volume. - Voice Activation - In addition to the push button, users have the ability to speak to begin the system process. - Heads-up Display - A display on the glass lenses to aid in relaying the information to the user. |
