Overview

This research project, conducted in a group of two, aimed to explore gesture-based interactions for adjusting privacy settings on Augmented Reality (AR) glasses as a bystander. Additionally, we investigated the type of feedback the device should provide to bystanders regarding its status.

My Role

• Conducted user research and data collection.

• Implemented the most mentioned form of feedback into the device.

• Utilized the Wizard of Oz method to simulate and test interactions.

• Analyzed results and provided recommendations for future improvements.

Problem

Rapid development of AR technology in recent years has made it more common to the public, which has raised concerns about the ability to record one's surroundings without consent. Currently bystanders have limited information whether they are being recorded by AR headset, and they have no way to enforce their privacy at their discretion.

Solution

Our research involved identifying intuitive gestures for bystanders, adjusting privacy settings on AR glasses and implementing a feedback mechanism that communicates the device's status clearly to bystanders.

Process

1. Initial Phase

• Gesture elicitation study: Collected data on intuitive gestures for interacting with AR glasses.

• User Interviews: Conducted interviews to understand user expectations and preferences.

• Wizard of Oz Method: Simulated interactions to gather realistic feedback without full implementation.

• User Feedback: Asked participants what kind of feedback they would expect from the device.

2. Feedback Implementation

• Implementation: Developed the most mentioned form of feedback into the device.

3. Second Phase

• Testing with Feedback: Tested the AR glasses and additional device with implemented feedback (Figures 3 and 4).

• Evaluation: Assessed user understanding and acceptance of the feedback provided by the device.

Tools Used

• Microsoft Hololens 2

• Arduino

Outcome

The study revealed that users appreciate the ability to adjust privacy settings using gestures. The gesture elicitation study identified clear preferences for gesture styles suitable for non-wearing users to adjust their privacy settings. However, the feedback mechanism provided by the AR glasses and additional device was not widely understood, indicating a need for further refinement.

Key Results:

• Identified intuitive gestures for non-wearing user adjusting privacy settings.

• Implemented and tested a feedback mechanism based on user input.

• Provided recommendations for improving user understanding and interaction with the feedback system.

Reflection

This project highlighted the importance of user-centric design in developing gesture-based interactions for AR devices. The use of the Wizard of Oz method allowed us to gather realistic feedback, leading to valuable insights for future development. The experience reinforced my skills in user research, prototyping, and usability testing.
