Excavator Navigation System Software User Experience Survey
您好，我们正在开展挖掘机导航/引导系统软件的用户体验研究，希望了解您在日常使用中的真实感受和建议。本次调研仅用于产品优化，所有信息将严格保密，请您根据实际使用情况填写。
1. What is your role?
Excavator Operator (Frontline Driver)
Surveyor / Technician
Construction Crew Leader / Project Manager
Equipment Dealer / After-Sales
Other
2. How long have you been using excavator navigation/guidance systems?
Less than 1 year (Beginner)
1–3 years
3–5 years
More than 5 years (Experienced)
3. Which software do you primarily use?
UniStrong
Trimble Earthworks
Leica
Topcon
CHCNAV
Other
4. In what scenarios do you mainly use it?
Highway / Railway Earthwork
Open-pit Mine / Quarry
Building Construction / Municipal Site Grading
Water Conservancy / Ditching
Other
5. When using the software every day, what are your biggest frustrations? Select up to 5.
Screen hard to read in sunlight, have to shade it with my hand
Buttons too small, can't tap accurately with gloves
Too many pop-ups, lose track of where I am mid-task
Data is hard to understand (e.g., NaN, abbreviations)
Calibration/alignment process too long, hard to remember
Switching attachments (bucket/breaker) requires re-entering a bunch of parameters
Icon meanings unclear, have to rely on memory
System keyboard blocks the screen when entering numbers
Slow response — bucket moves but screen numbers haven't updated yet
Lag / App crashes
RTK signal unstable, accuracy fluctuates
Other
6. In bright midday sunlight, which background color scheme is easiest to read?
Dark background white text (like the current Trimble style)
Light gray background dark text (like black text on white paper)
Auto-switch: light during the day, dark at night
Can't read any of them clearly, mainly rely on a sunshade
7. How long do you work in a typical day? Direct sunlight: ___ hours Nighttime / tunnel: ___ hours
8. NaN or incomprehensible numbers occasionally appear on the screen
1 (Never seen)
1
2
3
4
5
5 (Every time)
9. I can complete the calibration/alignment process independently on my own
1 (Not at all)
1
2
3
4
5
5 (Fully independent)
10. The bottom data bar (e.g., Cut Left/Center/Right) has large enough font size to read even when the machine is bouncing
1 (Can't read)
1
2
3
4
5
5 (Very large)
11. For the icons in the right-side toolbar, I can guess their function without training
1 (Can't guess at all)
1
2
3
4
5
5 (Can guess all)
12. The left-side red-green depth bar lets me tell at a glance whether I'm digging below or filling above grade
1 (Can't understand)
1
2
3
4
5
5 (Very intuitive)
13. The 3D bird's-eye view makes green lines basically invisible in sunlight
1 (Very clear)
1
2
3
4
5
5 (Basically invisible)
14. If I have color vision deficiency, the red-green color coding is not very helpful
Yes, I have color vision deficiency and need text labels
I don't have color vision deficiency, but adding text labels would be more reliable
I don't have color vision deficiency, colors are sufficient without text labels
Not sure if I have color vision deficiency
15. For day/night mode switching, which do you prefer?
Auto-switch based on ambient light (Recommended)
I'll switch manually — the machine shouldn't decide on its own
Auto + manual override (manual setting retained for 30 minutes)
16. How would you prefer the calibration process to be presented?
Step-by-step wizard: one step per page, with the 3D model highlighting the current calibration point on the left
Keep the current multi-layer pop-up approach
Step-by-step wizard + voice guidance
17. For attachment (bucket/breaker) management, which do you prefer?
Card library: each attachment shown as a card (3D image + dimensions), tap to select
Dropdown list selection
Auto-recognition via scanning (RFID/QR code tag on the attachment)
Manual parameter entry (current approach)
18. If you could redesign this software, what are the top changes you would make? Please describe your ideas.
