Cost comparison between the IVE and naturalistic studies.
| | Cost | IVE | Real road test |
| | Environment building | $3,500 | Thousands to millions for road reconstruction | | Additional bicycle components | $1,200 (Wahoo Kickr Climb + Wahoo Kickr Headwind + Wahoo Kickr Smart Trainer + ANT+) | Smartphone + software ($500) | | Headset | $1,500 (HTC VIVE Pro EYE) | >$10,000 (eye tracking glasses like SMI or Smart Eye Pro) | | Cameras | $50 (2 web cameras, $25 each) | $700 (2 GoPros, $350 each) | | Eye tracking software | Free (Tobii Pro Unity SDK + self-developed code) | $1,300 per year (iMotion academic) | | Video recording and integration | Free (open-sourced OBS studio) | Video integration requires a lot of label work | | Safety concerns | Very low | Potential risk to researchers and participants in the real road environment |
