Integrated System Build & Test
Team Vision for Integrated System Build & Test PhaseSummarize: Our team initially planned to test our design during this phase. However, due to delays, we focused instead on refining components for exhibit at Industrial Design Gallery Showing and Imagine RIT.
Functional Components DemoOur team will be demonstrating individual functions separately. To ensure all necessary functions are being demonstrated, we will break them down as follows:
- Provide means to carry tablet
- Harness prototype on mannequin, with mock track, displaying tablet case in use and hold position
- Provide easy access to tablet in various environments
- Demo model of moving system, with scaled-up track laid out flat such that slider/chain/pulley system can be operated by event attendees
- This demonstrates the functionality of the moving system, how the tablet will be physically moved from hold position to use position, and how the "gear" ratio works so that the length of the user's action is less than the length of the total tablet movement
- Provide hands-free means to use tablet
- Moving demonstration of tablet case folding and unfolding on crossbar
- This will consist of a 3D printed crossbar with free-standing grooves mounted to board to represent the tablet
- Crossbar will be mounted to a standing frame so that event attendees can manipulate the "tablet" to see the folding and unfolding action
- Provide tactile means of self-regulation, with customization, and
- Provide tactile positional information for selecting
- A working tablet (with AAC app) will have a grid-overlay to demonstrate the icon-selection
- This tablet will also have "texture plates" that can be added to the back of the tablet, with multiple textures to choose from
Status of Models and Prototypes
Due to our shifted goals, not all of our components have been integrated. Models have been updated and prototypes and demo models are in the works. Below are the team's latest Part Models and Physical Builds.
Above you can see models for the Tablet Case (top), Crossbar (left middle), Track Layout (bottom and right middle), Slider Assembly (bottom right and right middle), and Bead Pulley (lower middle).
This image shows the team's demo-ready Harness (top) and a near-ready prototype of the Slider Assembly (bottom).
Test Results Summary
Since no human subject testing was performed, we focused on creating assembly quality checks to have a specific measure of what is acceptable for display. These checks are available in the "Demo Components" tab of our "End of Semester Plan" spreadsheet available here.
Inputs & Source
- Revision of demo goals
- 3D models of parts
Outputs & Destination
- Assembly of parts
- New objectives and action items
Paper StatusPart of the final requirements for MSD is to write a full-length paper describing the project and the process we took to complete it. The paper outline has been created and the first rough draft has been submitted for review. Owner for this document is Christina, with editing help from Elizabeth.
Poster StatusOne of the other things we will need for our demonstrations is a poster that adequately explains the purpose of the project. The team has discussed different points to put on the poster in order to reflect all of the background work that has been done that might not appear in one of the psychical demos. Poster layout is in the works, along with theme selection. Owner for this document is Mick, with technical input from Christina and Elizabeth.
Process Book StatusThe process book is an Industrial Design requirement which visually walks through the entire project process, from research and conceptualization to building and testing. The process book has been a year-long work-in-progress. Owner for this document is Mick.
Risk and Problem Tracking
Functional Demo Materials
Functional Demo Objectives for Imagine RIT have been planned and can be found in our calendar document. We plan to have various interactive displays to show the different components and subsystems present in our design.
These displays will include the following:
- A static model of the harness with the tablet fixed in use position
- A demo of the pulley and slider system used to move the tablet between storage and use position
- A demo of how the crossbar will move the tablet into a comfortable use angle
- An interactive iPad with an AAC application and removable texture plates.
Plans for next phase
Below is a section of the end-of-semester calendar. Most of our action items were set for early this week, with plenty of "wiggle room" before things are actually due to ensure we still have time when things inevitably fall behind schedule.
Important dates to note are:
- Poster draft due 4/14/17
- Paper draft due 4/20/17
- Gallery showing is 4/25/17
- Peer-review of paper is also 4/25/17
- Imagine RIT Poster due 4/27/17
- Imagine RIT is 5/6/17
- Final Presentation (single slide) due 5/9/17
- Paper deadline is 5/11/17
