Question 1.4: Design for you

The Question 1.4: Design for you homework for Week 1 of Design: Creation of Artifacts in Society required me to design an artifact that addresses my user experience gap of a solution that supports and encourages an efficient and affordable contactless ticketing system for public transport by creating a visual expression of the design as well as a simple prototype of the artifact.

Visual expression of the design, including dependent and  alternate technology.

Flip rig: An extremely light-weight and simple rig for a FLIP MinoHD video camera

A project at work required video footage of a series of veterinary surgical procedures to be recorded for inclusion in an online resource. The project did not have resources (DSLR and personnel) to record the series of surgical procedures nor does the relatively small operating theatre permit an additional non-surgical staff member to occupy the theatre.

With these constraints in mind, I designed and assembled a camera rig from a number of different pieces of hardware to support a Flip MinoHD digital video camera (found in the back of an old storage cupboard) that could be used to record each procedure. The simple  nature of the Flip video camera means that any member of surgical team can start the recording prior to the commencement of the surgery without having to consider the possible complication of operating a semi-professional video camera or DSLR. The light-weight and unobtrusive nature of the Flip also allows the camera to be fitted to the arm of the surgical light. A perfect place to capture a bird’s-eye view of the surgical procedure.

I don’t always require an affirmation, but when I do, I prefer the Bene Gesserit’s litany against fear

Inspired by Tom Woodwards’s Dune-themed tweet on 24 April 2014, Rhys Fulber and Bill Leeb’s production on Fear Factory’s Fear Is the Mindkiller EP and the Bene Gesserit’s litany against fear and based on Jan Vantomme’s Drawing text and Running your sketch on an Android device  Processing recipes on Github, I created this portable litany against fear as a fun exercise in combining , expanding and learning further from the recipes I’ve worked through so far.

Extending the functionality

I’d like to extend the portable litany against fear by creating functionality that allows for use of:

  • sound by including pre-loaded audio samples that play as each line of the litany is displayed
  • custom text and audio affirmations to be entered by users
  • events such as display of text and playing of audio or other events to be triggered by touching and swiping of screen by the user.

Augmented contextual instruction user experience (Object tracking)

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.
