Week 13 marks the beginning of the final phase of the module, but for me it still feels like a period of research and further development rather than final production. By the end of Week 12 I had moved away from thinking about airport accessibility only through fixed interventions such as sensory rooms, quiet spaces or familiarisation tools. My research was beginning to suggest that the more important issue might be how support could respond to the individual as their needs change throughout the journey.

The adaptive VR research from the previous week gave me an important starting point because it showed that an environment does not have to remain static. Physiological information such as heart rate could potentially be used to influence what happens inside an immersive environment, creating a more personalised response rather than giving every user the same experience.

This week I wanted to understand that idea in more depth. I started following references from the VR and biofeedback papers into research around anxiety detection, machine learning, physiological monitoring and the use of biosignals within interactive systems. I was particularly interested in what information the body can provide, how reliably it can be interpreted and what happens after a change has been detected.

The project is beginning to move from designing an accessible environment towards exploring whether accessibility itself could become responsive.

I do not yet know what the final technology will be, and I do not want to decide that too early. At this stage, VR is still useful as a precedent, but I am becoming more interested in the wider system behind it: sensing a change, interpreting that information and deciding how support might respond without taking control away from the traveller.

The main questions I want to explore this week are how physiological signals relate to anxiety and arousal, whether machine learning can identify useful patterns within those signals, and whether a responsive system could use this information in a way that remains personalised, discreet and under the user's control.
