Navigation Band Navigation system for visual impaired person

User-centered design
Human-computer interaction
Design making Navigation band is designed for visual impaired person in assistancing their nagivation in walk and provides visual information with sound. Employing hanger reflex phenomenon, navigation band turns user’s head in a nature way so as to guiding them. It’s designed light-weighted, so as to fullfill user scenario of daily commute.

What obstacles visual impaired person meets in their lifes?


They have a hard time in their daily commute because they often cannot distinguish between objects and even judge the path of their behaviour.  Secondly, visually impaired people can also have problems with reading. On the mean while, they also encounter problems reading hall marks.  

How it works? 

The navigation band have two work flow. It first captures environmental information and offer imformation to user. It also recieve feedbacks from users and adjust guiding proposals.
What is hanger reflex and how it helps?

Discovered by KAJIMOTO LAB, when a wire hanger is placed on the head, the head rotates involuntarily. This phenomenon is called as the “Hanger Reflex”. Hanger Reflex is a phenomenon that produces an illusory force and involuntary rotation of the body parts.

Outdoor information classification



• Standard and static objects: objects that share identical properties and still. Such as pedestrian crossings, lights.
• Standard and dynamic objects: objects that share identical properties but changes. Such as traffic light and roadblocks.
• Random and static objects: objects that appears randomly and still. Such as special hallmarks and obstackes.
• Random and dynamic objects: objects that appears randomly and dynamic. Such pedestrian, cars, bikes.
To better develop the indentification technology of this device, the environmental information should be collected and classified. Respondents were asked to simulate a visually impaired person commuting around the city and interviewed about their feelings. I divided the outdoor objects into four categories: Indoor information classification

The difference between indoor and outdoor environmental information:
Compared with outdoor environmental information, indoor environmental information is more abundant which lead to higher information density. Therefore, a more effective HCI approach is expected.



The focus of ‘navigation’ changes from guiding users where to go and avoiding accident, which could be concluded as ‘guiding’, to assisting them to search objects, read print information, pick up goods, which could be concluded as ‘communication with the world’, when people walk from outdoors into indoors.
Modeling







 By rotating the outer circle, user could interact with the band: Rotate the outer circle clockwise once means reporting current directing situation.

Rotate the outer circle clockwise twice means redirecting.
Rotate the outer circle counter clockwise once means reading indoor information
