Augmented contextual instruction user experience (Object tracking)

Leave a comment

Screen captures from the completed object-tracking augmented contextual instruction user experience.  The augmented contextual instruction is made up of a sequence of junaio channels that can be browsed in the junaio AR browser. For this example, the channels were browsed using junaio on an iPad.

Step 1: Remove bracket from caliper
Place the assembled rear brake caliper on the workbench with the retaining bolts facing towards you.
step_01_screen
The first step in disassembling a rear brake caliper is to remove the bracket from the caliper. Use a spanner to loosen the retaining bolts.
step_02_instruct
Remove the bracket from the caliper and then place the bracket on the workbench facing towards you.
step_02_screen
The second step in disassembling a rear brake caliper is to inspect and clean the retaining bolts and remove the rubber seal from the bracket.
step_03_instruct
Put the bracket to one side. Place the caliper upside down on the workbench with the inlet port facing away from you.
step_03_screen
Insert the air tool into the fluid inlet port of the caliper.
step_04_instruct
Turn the caliper over with the cylinder bore facing towards you.
The fourth and final step in disassembling a rear brake caliper is to remove the piston seal from the caliper.
Use a pointed tool to remove the piston seal from the caliper.
Disassembly complete!
You have now completed the final step in disassembling a rear brake caliper. Remember to inspect and clean all parts before reassembly.

Gathering 3D point cloud with Metaio Toolbox

Screen captures from 3D point cloud data gathering with Metaio Toolbox for sequences to be used in my augmented contextual instruction on the rear brake caliper. The 3D point cloud data will then be used as tracking technology to place my augments.

3d_point_cloud_caliper_complete
A rear brake caliper. This 3D point cloud will be used to place an augment for the first step of the rear brake caliper disassembly sequence.
3d_point_cloud_clean_bot_pins
The bracket from a rear brake caliper. This 3D point cloud data will be used to place an augment for the second step of the rear brake caliper disassembly sequence.
3d_point_cloud_remove_piston
An overturned rear brake caliper. This point cloud data will be used to place an augment for the third step of the rear brake caliper disassembly sequence.
3d_point_cloud_remove_seal
A rear brake caliper with the piston removed. This point cloud data will be used to place an augment for the fourth and final step of the rear brake caliper disassembly sequence.
