Ribbon - Chart

The DSM: Short Distraction has a unique section on the Graph ribbon, in which you can find some plugin-specific tools.

VBTS_DSMShort_Ribbon_Chart.svg

Event

VBTS_DSMShort_Ribbon_Chart_Event.svg

Add t-Away

Add a t-Away event to the test by clicking on the Add t-Away button with the cursor at the required location in the chart. 

When you add a t-Away event you must add a corresponding t-Road event. 

Add t-Road

Add a t-Road event to the test by clicking on the Add t-Road button with the cursor at the required location in the chart. 

When you add a t-Road event you must add a corresponding t-Away event. 

Selected Event

When you have added one or more events to the test, the selected event will be displayed. Click on the dropdown arrow next to the event name to see the available events in the test and select a different one. 

Rename

You can rename the events in the test. Select the required event and click Rename. 

Delete

You can delete events from the test. Select the required event and click Delete. 

Plugin Tools

VBTS_DSMShort_Ribbon_Chart_PluginTools.svg

Back -4s

Click on the Back -4s button to move the cursor to 4 seconds before the start-of-test point in the chart. 

Toggle Metronome

Click the Toggle Metronome button to enable a click track of 120 bpm. You can use this to keep time and trigger "look away" and "look back" actions required for the test. 

Toggle Line Results

The short distraction test is made from multiple on/off triggers in a single test run, so we have added the extra functionality to toggle the line results. Click on the Toggle Line Results button to show or hide the individual line data from each trigger on/off activation. This is useful for post-processing of individual line results. For example, to assess where a test was out of bounds. 

Test Results Area

The Test Results area displays instantaneous results from the current test session. In this area, you can review test-specific criteria such as the duration from test start to Visual / Audio warning, as well as the overall PASS/FAIL result.

You can review the live results and assign any edge cases to be considered for further review offline.

Every time you start a new test (via the START button on the dashboard), VBOX Test Suite will add a new tab to the Test Results area. This gives you the ability to switch between separate tests (for example, different Gaze locations). You can remove a session from the Test Results area by clicking the X icon on the tab.

Rename File

You can rename a session tab by double-clicking the tab header. Changing the name on the session tab in the software will automatically change the name of the locally saved VBOX file (.vbo or .vbb).

Edit Session Data

By pressing the Edit Data button next to the name of the session in the Test Results area or on the Test Setup tab on the ribbon, you can add vehicle and test information to the session.

  • When in Offline mode, this information will be saved into the VBOX file, meaning that this information will be recalled every time the file is loaded into VBOX Test Suite.
  • When in Online mode, a newly created session will be populated with session data from the previous session.

This information will be included in the test report to make it easier to see under what conditions the test was conducted.

To save time, you can import and export the session information for use in other sessions (the entire range of data is exported, not just the visible screen).

Once the session information has been completed, you can export the data to a .vbses file. This file will contain all the session information that can then be imported into the open session information field.

Note: This data is purely optional and does not affect the test or the test results. 

 

Result Columns

VBTS_DSMShort_Results.svg
 

The Test Results area has the following default columns:

Run Indicates which run number the results relate to, with run one being the first run completed.

There is also a selection box that, when ticked, includes that run in the graph and into the Average/Max/Min/Standard Deviation calculations. Once selected, a coloured square will appear to indicate which colour this run is displayed as on the graph.
 
Note: If you are loading a file in Offline mode, all valid runs will automatically be ticked.
