Accuracy of feedback provided


No transition between indoor / outdoor navigation


Power
-
drain / battery life


No conveyance of terrain and environment


Cumbersome systems


Isolation and exclusion of user


Review of User Requirements

Interviews and walkabouts with students / mobility
trainer



Questions:


Comment on campus navigation issues


Issues associated with specific routes


Strengths / weaknesses of mobility training


Describe thought process during walkabout


Guide dog / cane users






Results of Review (1)


Differences between dog / cane users

Use of environmental sounds / cues


Primary means of determining position


Confirm information obtained through other
means


Use of different manholes as route
-
markers


Use of the river / wind direction



Results of Review (2)


No off

shelf system meets UCC's needs

All systems fall short in following areas:



Accuracy level of feedback


Reliability of localisation information


Inability to operate both indoors / outdoors


Nature of interface feedback



Navigation Layer

vendor interoperability


Included in new devices


iPhone 4S



Wireless Inertial Measurement Units (WIMU
)


Capture optical 3D motion

User Interface Layer


Address issues apparent in other systems


Retain all beneficial elements from other systems




Existing systems
