From Forced Exposure to Real‑World Prevention
Traditional anti‑smoking campaign tests often rely on forced exposure: participants sit in front of a screen,
look directly at prevention posters and answer questions in artificial lab conditions. In daily life, people
never encounter prevention messages this way. Posters and billboards appear at the edge of attention while
people focus on getting somewhere, meeting someone or doing something else.
Dr. Solenne Bonneterre's doctoral work at Université Paris Nanterre set out to solve this ecological‑validity
problem. By using immersive virtual reality and a multisensory VR cabin supplied by SENSIKS, her research team
could place participants in realistic urban environments where anti‑smoking posters competed with everyday
stimuli – just like in real streets and public spaces.fileciteturn1file0
How the Study Worked
Participants entered a three‑dimensional VR city and performed a primary task: navigating streets, following
routes and finding locations. Tobacco prevention posters and, in some cases, tobacco advertising were integrated
naturally into the environment. The SENSIKS system, equipped with eye tracking, measured what people actually
looked at while they were busy with their navigation task.
- Eye tracking: captured directed gaze, fixation time and viewing patterns for each poster.
- Exposure duration: measured how long posters remained in the field of view, including peripheral exposure.
- Recognition tests: after the VR session, participants identified which posters they remembered seeing.
- Attitudes and intentions: questionnaires assessed perceived impact of messages.
What the Research Found
- Under realistic incidental exposure, people correctly recognised only a small number of posters, often one to two per session.
- Many participants made multiple false recognitions, showing how hard it is to remember specific messages in busy environments.
- Negatively framed "fear appeal" messages did not automatically outperform positive or neutral messages when shown incidentally.
- When anti‑smoking posters competed directly with tobacco advertising, prevention messages achieved slightly higher recognition – but both performed modestly, highlighting how intense real‑world attention competition can be.
These findings challenge the assumption that strong visuals or fear‑based messages are enough. In real streets,
posters must first win the battle for attention before they can influence memory or behaviour.fileciteturn1file0
Implications for Campaign Designers and Public Health Teams
The core message from this research is simple but powerful: if a message is not seen, it cannot work.
Multisensory immersive VR, combined with precise eye‑tracking data, provides a practical way to evaluate whether
campaign materials genuinely break through the noise of daily life.
Instead of relying only on intuition or isolated focus groups, teams can observe how people move through complex
environments, what actually attracts their eyes and what sticks in memory afterwards. This leads to better‑informed
creative choices, more efficient media spending and, ultimately, more effective health communication.
