Abstract
A wearable neck device includes an IMU coupled to the wearable neck device and adapted to detect inertial measurement data and a GPS coupled to the device and adapted to detect location data. The wearable neck device further includes a camera adapted to detect image data and a memory adapted to store data. The wearable neck device further includes a processor adapted to recognize an object in the surrounding environment by analyzing the data. The processor can determine a desirable action based on the data and a current time or day. The processor can determine a destination based on the determined desirable action. The processor can determine a navigation path based on the determined destination and the data. The processor is further adapted to determine output based on the navigation path. The wearable neck device further includes a speaker adapted to provide audio information to the user.
