| Our project is to create an echolocation sensor using ultrasonic waves that can determine the characteristics of a room or objects in front of the sensor and output that information to the user. The device outputs an ultrasonic chirp through an ultrasonic transducer. The reflected signal is received through another ultrasonic transducer and relayed through amplification, filtering, and offset circuitry to an ST Discovery dsp board. The dsp is used to complete calculations for obtaining the information about the room/object from the chirp impulse response. Characteristics such as distance between the object and the sensor and shape of the object are sent out through a serial link. This is a sister-project to the "Extended Reach" Haptic Array. The final goal is to combine this sensor with the haptic array to create a new sensory experience that would allow someone to locate objects in a room without the use of sight--something that would be great for blind people. A potential application for this technology would be within a blind user's cane, where the user can inobtrusively "feel" his environment. |
