Naer Toolbar Redesign - Usability Research Synthesis
- 2. Background Purpose of Research: To validate the effectiveness of the redesigned toolbar in the NaerVR app. Key Focus: Improved visibility, accessibility of the toolbar and icons, and efficiency of the new wristband activation method.
- 3. Research Goals Are the tools and their icons easily recognizable and intuitive to use How does the redesigned toolbar compare to previous interfaces in terms of usability and functionality Which aspects of the redesigned toolbar did you find most helpful What are the key areas for improvement to enhance the toolbar’s accessibility and support for collaborative tasks?
- 4. Methods & Approach Usability testing, to assess the visibility and clarity of the toolbar and its icons, aiming to identify and address any usability concerns. Participants first viewed the toolbar on the existing Naer app, then tested the VR prototype for comparison Participants were asked to identify and select each tool from the redesigned toolbar to ensure icons are intuitive and visually distinct Participants were asked to describe what they see and what they do out loud. Tasks:
- 5. Questionnaire How easily were you able to locate the toolyou needed Were there any tools or icons that you found difficult to recognize How intuitive was it to interact with the toolbar Which aspects of the redesigned toolbar did you find most helpful Was there anything about the toolbar that you found confusing or frustrating How does this toolbar design compare to your experience with other VR interfaces Were there any tools or functions you expected to find but didn’t What suggestions do they have for how we could improve the toolbar's accessibility?
- 6. Key Insights
- 7. Key Insights 4/5 Participants Easily recognized tool icons and read the tool names "The names on the toolbar are very clear, I didn’t have to squint or guess." - Stephani "It was easy for me to figure out what the tools were without reading their names." - Puja “The icons stand out well against the dark background." - Ray
- 8. Key Insights Appreciated the hover effect on toolbar 4/5 Participants "Hovering over a tool gave me a clear indication of what I was selecting. Loved it." - Zeyne "The hover effect helped a lot, I knew exactly where I was pointing.”- Ra "I really like the colored background when i hover over the tools" - Pujan
- 9. Key Insights 2/5 Participants Reported issues with feedback on tools "The sharpie didn’t show much change when selected, which was confusing." - Puja "It was a little confusing when different tools had different effects when selected.” - Pooja
- 10. Key Insights 1/5 Participants Expressed confusion recognizing the Laser Pointer "I had to double-check the laser pointer, but the rest were straightforward." - Pooja
- 11. Recommendations Redesign the visual cues for selected tools to ensure they are distinctly noticeable. Rationale: Participants like Pujan expressed confusion due to minimal changes in the tool's appearance upon selection. Ensure that hover effects are consistent and informative across all toolbar items. Rationale: The hover effect was praised for its clarity and helpfulness in tool recognition.
- 12. Recommendations Implement navigation aids such as 'Next' and 'Back' buttons to facilitate easier access to tools. Rationale: Two participants appreciated these features for reducing the need to turn their heads excessively, suggesting that enhancing these aids could benefit all users. Develop Clearer Documentation and Tooltips for each tool. Rationale: Although tool recognition was generally high, instances like Pooja’s second look at the laser pointer indicate that some users could benefit from additional context or information, particularly when encountering less familiar or more complex tools.
- 15. User Perceptions of Lo-Fi Solutions & Prototypes 6/9Participants found the in-app keyboard for sticky notes a significant improvement in text input. 9/9Participants recognized the need a trash icon for content deletion. 8/9 Participants found the implementation of undo/redo buttons to be a crucial feature, allowing for easier error correction and editing. 4/9 Participants expressed a desire for a more comprehensive toolbar for its potential to streamline workflows, 5/9 Participants were favorable towards the idea of Quick Teleportation options for efficient navigation within the virtual environment.
- 16. Participant used both hands to access tool bar. Participant used mic as they would a pen to write. Participant assumed the sponge would erase text on sticky note. Participant confused voice typing with voice assistant.
- 17. Recommendations - contd. Simplify Navigation: Introduce a shortcut to teleport to a specific spot in the environment Streamline Sticky Note Editing: Add basic text editing features such as undo, redo, and erase to the sticky notes function, making it as simple as using physical sticky notes Accessibility Enhancements: Increase the contrast and size of text and icons to make them easier to see and use for all users, especially those with visual impairments.
