Motivations
• A visibly impaired person has limited freedom to
roam around public areas � only limited to familiar
places.
• Smart phones are widely available and affordable
• Smart phone-based indoor positioning technologies
which rely on built-in wireless interfaces and sensors
are maturing
• A cost-effective application for visibly impaired
• MIMOS working on indoor positioning
application for local retail market

Current Challenges
• GPS unavailable indoor
• Most commercial indoor positioning technologies requires expensive infrastructure setup
• There are still many research problems in indoor positioning especially on lower cost approaches
• Lacked of commercial motivations to support the handicaps

Proposal
• A mobile application which provides a better
real-time spatial or location awareness to the
visibly impaired
• Rely on wireless interfaces and sensors
• Example applications:
� Find retail items and how to get there
� Find public amenities such as toilet, info desk, drinking water machines, rubbish bin, etc.
� Hazard warnings e.g. construction or cleaning in front, dangerous object on the floor, etc.
� Inform your buddy where you are

2) Orientation and Mobility
• How to establish direction, movement and speed?– Magneto, gyro, accelero + filters
• How to instruct user?– Language
– Instruction composition
– Context-aware
• How to manage surrounding objects/events?– Classification
– Notifications
