AR Light Controller

How does AR-supported lighting adjustment influence users’ ability to interpret and manipulate lighting environments for personal goals?

Project Description

In class activity

CSCI 1951T Project 2 final

A light(temperature) adjusting tool in passthrough mode by using assisted UI.

A scenario-based task would be given to participants. Participants will use both their mobile phone and the AR tool to adjust the lighting to make the room ‘feel cozy for guests.’

​

1. Participants will take a photo of the space and use the photo editing tool to adjust the temperature. (reference attached)

​

2. Participants will use the AR tool (color temperature sliders or lighting presets) to control lighting.

Mental demand was slightly higher in AR (avg: 3.89) than in mobile (avg: 3.67)

Suggests that while both were manageable, AR required slightly more cognitive effort.

​

Physical demand was notably higher in AR (avg: 2.33) than in mobile (avg: 1.56).

Users reported less frustration in AR (avg: 3.11) than in mobile (avg: 3.56).

Indicates the AR environment, while more demanding, was smoother or more engaging.

​

​

Even though AR took more time and was more demanding mentally and physically than mobile, it rated a higher overall experience.

Confidence was high for both platforms, slightly higher in mobile (8.56) than AR (8.22).

​

​

​

Clarity of interaction rated similarly with the average score of mobile: 7.89 and AR: 8.11.

  • Both platforms are effective for adjusting lighting, with AR offering a more immersive but slightly longer and physically demanding experience.

​

  • Participants found AR more engaging and surprisingly smooth despite higher demands.

​

  • Consider offering in-AR guidance or visual cues to improve clarity and reduce initial friction, especially for new users.

Takeaways

Challenges

Eunjin

Explored meta quest camera access

Strengthened foundational Unity skills: Built basic understanding of UI setup, VR interactions, and passthrough adjustment.

Engagement insight: Participants found AR more engaging and smoother to use than expected, even though it was more mentally and physically demanding.

Difficult to match baselines between mobile and AR platforms: baseline brightness, warmth levels, environment consistency

Not enough information of iphone editing increments

Lighting color (shader) is still an approximation

Need for better activity setup:Clearer, more detailed instructions and prompts could help collect more consistent, clean user data.
