Graduation ceremony for the 2013 Specialist Scholarship

VET Development Centre CEO Denise Stevens opens proceedings for the 2013 Specialist Scholar graduation ceremony.

Today I attended the graduation ceremony for all 2013 VET Development Centre Specialist Scholars. The graduation ceremony was the final event for all recipients of this year’s Specialist Scholarship. The event featured an opening address and presentation of certificates and a gifts to all scholars from VET Development Centre CEO Denise Stevens.

The graduation ceremony also featured an amazing presentation from Terese McAleese, Director of Learning at Swinburne University of Technology. Terese spoke about her journey as an immigrant from 1980s Belfast to Melbourne as well as her journey in vocational education and training (VET), from a student to an administrator and teacher and finally to a professional responsible for designing learning experiences. Terese also spoke about the transformational nature of the VET sector and TAFE, a place where skills could be developed for the direct application in industry as well as a place for second chances or opportunities for education that might have been missed the first time. The chance for a new or better life.

A solution to the challenge of using markers placed on the floor to trigger and then engage with an augment containing a 3D object modelled to scale

Using Simultaneous localization and mapping (SLAM) or mapping a room (creating a 3D point cloud) or environment with Metaio Toolbox could be a solution to the challenge of using markers placed on the floor to trigger and then engage with an augment containing a 3D object modelled to scale.

Augmented contextual instruction user experience (Image tracking)

Screen captures from the completed image-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
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 2: Inspect and clean retaining bolts
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 3: Remove piston from brake caliper.
Insert the air tool into the fluid inlet port of the caliper.
Step 4: Remove seal from brake caliper
Use a pointed tool to remove the piston seal from the caliper.

Once the bolts have been loosened, you can then use your fingers to remove them. You can check out the How to disassemble a rear brake caliper playlist on YouTube.

(Unfortunately) I think someone may have heard correctly!

Someone in the Metaio Developer Portal said they’d heard the UI Designer in Creator was made for iPhone4 screens and the created UI design is not responsive to different screen sizes. I think that someone may have heard correctly. Damn!

Yes. It’s still one to prepare and one to publish.

And another thing. It’s been 11 days since I posted my issue with Z translation of buttons in UI Designer of Metaio Creator 2.6 to the Helpdesk of the Metaio  Developer Portal and there hasn’t been one response! Damn.

Too many glowing screens if you know what I mean.

Placing geometry in the 3D point cloud in Metaio Creator 2.6

Placing geometry in the 3D point cloud in Metaio Creator 2.6 is a little cumbersome, bewildering and often inaccurate. It takes lots of clicking and seemingly random fiddling to place geometry. You also can’t really determine if your geometry is placed correctly within the 3D point cloud until you upload to your channel and then view your channel in Junaio on your device. If it’s not placed correctly, you need to tweak it in Creator, publish it and then view it again in Junaio. Repeat process until it looks like it might almost be placed correctly. Curious.

Testing image tracking with UI elements for each step of the disassembly process

Screen captures from my image tracking tests in Junaio for each step of the disassembly process with UI elements. Unfortunately, due to my Z translation problems in UI Designer of Creator 2.6 I had to remove the background image which was placed underneath the buttons. Doing this gives the buttons a floaty and slightly random feel, but at least the buttons function as they should!

Lost in Metaio Creator’s Z translation

I’m currently wrestling with the correct Z translation of images and buttons in UI Designer of Creator 2.6. I’ve placed some buttons on top of an background image in the UI Designer of Creator and have encountered a problem where the image obscures the buttons and prevents them from working. I’ve checked the Z translation of the image in relation to the buttons and have made sure the buttons translated above the background image, but this doesn’t seem to make a difference when the published channel is viewed in Junaio on my iPad.

I’ve posted my issue with Z translation of buttons in UI Designer of Creator 2.6 to the Metaio Helpdesk and look forward to hearing from someone in the community.

While attempting to solve this problem on my own in Creator, I experimented with placing the buttons partially over the background image and then publishing to my channel. This had an interesting result. The button displays and functions correctly!

Here are some screen captures of the properties windows for the background image and each button in the UI Designer of Creator and the published channel viewed in Junaio on my iPad.
