Pre-Trip Inspection Enablement & Feedback

Email Enablement:

⁠

General Methodology

This feedback has been informed by a decade of experience and principles of cognitive science and instructional design

We did user testing to see where people got stuck and then used the above principles to inform our proposed solutions

Interactivity

Generally, our users had friction as it pertained to the controller interactions, including acclimation, grabbing objects, turning knobs etc.

There were areas where, if a specific action wasn’t done correctly, there wasn’t a way to skip through, or a maximum time out to avoid the learners getting lost. This is crucial and fundamental to all of our trainings.

Based on our user testing, we found that an average learner demographic for training isn’t tech savvy enough.

Interaction/Navigation

When I grab for my tablet, it doesn’t enter my hand.

Expand object hitbox: all objects should have a much larger selection volume or hitbox so that so that if I’m not wuite in front of an object I don’t have to reach too far to grab it virtually. I should not be penalized for not quite reaching or aligning with an object.

EXPERIENCE INTRODUCTION

Instructional Design

I don’t have a clear conceptual framework of what I’m going to be learning and/or assessed on. I don’t know how it ties more broadly to my work as a trucker.

Add LOs: explain verbally and via graphics the structure of the experience and what I should be taking away from it cconceptually.

CHOCK PLACEMENT

Interaction/Navigation + Instructional Design

I didn’t know what I was learning when I was asked to place the chock and I couldn’t reach the tire to place it properly because I was sitting.

If we are TRAINING proper placement, decouple gross motor movement from spatial mental modeling and visual object recognition, ie require the learner to select the tire, then bring the tire to the learner’s eye level and have them place the chock freely beneath the tire. Provide tailored and immediate corrective feedback if they place it incorrectly.

If it is an ASSSSMENT, do not show learners outline of how chock should be placed.

I can’t read the gauges on the dashboard.

Bring gauges closer to learner: decouple gross motor function and spatial awareness from visual object recognition and comprehension. These are separate skills. In other words, have the learner select the gauges to come to you the learner so they can inspect them without requiring too much movement.

Pitfalls

Controller Mappings

1 - Critical

For the scope of this training, you would be using the following buttons:

Trigger button + Grab button to hold objects

Headset Gaze to view and inspect objects

Recommended Boundary Setting

1 - Critical

Following boundary and config settings are recommended:

One can conduct the training in a “sitting” state

Preferably choose a “Medium” boundary since you may need an arms length of space.

Picking the right training

1 - Critical

Use your virtual hands to pick up the “Challenge” cartridge and place it in the cartridge.

Make sure to use both “grab” and “trigger” buttons to pick up the cartridge

People tend to drop the cartridge quite frequently and it doesn’t come back instantly.

Pressing the Start Button

1 - Critical

Users were not super sure on when exactly they should press the start button

Clicking on the Placards

1 - Critical

A user can use either their left hand or right hand to click on placards by hovering their hand close to the placard

Please know that there might be occlusion wherein your hand may look as if it’s behind the placard. Just make sure you reach the “OK” button and it lights up, and it should automatically click.

Grabbing and Pulling

1 - Critical

The user may have to pull the knob by moving the controller hand substantially to pull the valve “virtually”. This represents the amount of motion it may need for a user to pull the truck knob in real life.

Bending Forward to Lift Objects

1 - Critical

There are instances where the user may have to bend forward to move objects. Thus, the user may want to ensure that there is an arms length worth of free space to do safely.

Turn On / Off 1 by 1

1 - Critical

Make sure to turn on the windshield wipers 1 by 1.

Make sure the user doesn’t turn the wiper off until all of them have been turned on.

Turning Knobs

1 - Critical

Make sure to turn on the high beams first, check the box and then turn them off after checking the box

High beam: Turn the knob upwards

Low beam: Turn the knob downwards.

Turning the knob off and on can be really confusing and there are instances where users will pre-check the low and high beams but the experiences will still ask them to turn on and off the knobs.

To-Do-List

2 - Important

The checklist will always be anchored to the user, underneath their eyes, close to their waist.

At any point of time throughout the training, the user can grab it and hold it, with either their left or right hand, to check of items from the list.

Grabbing & Moving Objects

2 - Important

The user may have to grab and move objects within the training. In this specific example, it involves grabbing and placing a stopper under the truck wheel

Grabbing and Lifting

2 - Important

Training may also involve grabbing and lifting objects which requires both “Trigger” + “Grab button plus hand motion.

This is why an arms length of space around the user would be helpful.

Grabbing Headlights & Lates

2 - Important

The user may have to grab headlights, number plates and the bumper but this may not be super helpful for a user.

Training vs Assessment

2 - Important

There is no reference for what constitutes a leaking or damaged engine.

Add a “training” exprieence to this module or incorporate feedback and guidance at each checkpoint when a learner fails.

Headset Gaze

3 - Minor

The user will need to inspect by looking at the highlighted area.

The user gaze will be marked by the focus signs that will help them inspect specific objects.

Shiny NPC

3 - Minor

NPC has a shiny lining around it which can be a little distracting

Checking Off the List

The user will have a checklist that they will need to check off within the training.

This will require them to press the box that needs to be checked for a period until the yellow progress bar fills the whole box.

Once done, a tick mark should appear and the user will know if they’ve answered the question correctly or not.
