When the sight impaired become mobile, they often bump their heads on unseen objects and/or hazards that could result in injury. The object detection device uses signal emitting proximity sensors that alert the user to unseen objects. The object detection device notifies the user of detected objects. Stimulators, such as actuators, produce a detected feedback to contact the user to warn the user that an object has been detected and the distance between the object and the user. Each actuator contacts the user at a specific contact point. The actuator contacting the user at a specific contact point informs the user of the distance between the user and the detected object.
