• What - HandSCAPE?
• Traditional measuring tape with digital
  functionality.
• Why - do we need one?
• Digitize field measurements
• Portability
• Space Optimization
• Improve productivity and efficiency
• Simplicity and ease of use

Paper discusses few other devices like ShapeTape.

• How - HandSCAPE concept?
• Linear Distance
• Orientation sensors Angular Information
• Capture Spatial Information
• Relative Positions fixed reference point

• Where - 3 On-site application areas
• Optimal Packing in Storage and Transportation
• Archaeological field measurements
• Interior Designing

4
Optimal Packing Algorithm
5
Archaeological measurements include pitch,
heading, length height.
6
Interior Design measurements include spatial and
3D dimensions.

• More Details
• Storage
• Sort by volume
• Greedy Algorithm
• Archaeological Survey
• Rectangles
• Length, Pitch, Heading Height calculations
• Interior Designing
• 3D, spatial and vector measurements

Implementations Data Processing, Wireless
Communication

• Case Study Storage
• 2.1 times faster than a normal tape
• 77 were more accurate

• Limitations
• Pushing buttons repeatedly.
• Orientation affected by magnetic fields
• Other applications need more accurate
  measurements

9

• My Evaluation
• Easy and efficient storage
• Not really portable Base unit has to be 30-50
  feet
• Magnetic interference affects orientation
• Multiple button push affects
• May not be accurate for other applications
• eg. Archaeological measurements
• Needs usage based improvements.

10

• Enhancements
• Curve measurement
• Built-in feature to digitize and view
  Portability
• Laser techniques
• New features to correct transmissions
