A robotic cane based on interactive technology

摘要

A human-friendly interactive system, based on the harmonious symbiotic coexistence of humans and robots, is explored. A new paradigm of technology, interactive technology, is investigated to seek such an overall interaction through Korperlichkeit (corporeality or embodiment). Based on this Interactive technology paradigm, a robotic cane is proposed for blind or visually impaired travelers to navigate safely and quickly among obstacles and other hazards faced by blind pedestrians. The proposed robotic cane "Roji" consists of a long handle with a button operated interface and a sensor head unit that is attached at the distal end of the handle. A series of sensors mounted on the sensor head unit detect obstacles and steer the device around them. The user feels the steering command as a very noticeable physical force through the handle and is able to follow the robotic cane's path easily and without any conscious effort The issues discussed include methodologies for human-robot interactions, design issues of interactive robotic cane, hardware requirements for efficient human-robot interactions.
