Imagine a world where you could control your virtual reality (VR) experience with physical control panels attached to the back of your head-mounted unit (HMD). Welcome to the realm of FaceWidgets, an innovative system that seamlessly blends the physical and virtual worlds.
Interchangeable Control Panels for Immersive Experiences
FaceWidgets are interchangeable physical control panels that reside on the backside of the HMD. When you place your palm near your face and headset, an on-screen canvas appears, allowing you to manipulate widgets both physically and in the virtual world to control your experience. This intuitive design eliminates the need for controllers and enhances immersion by providing tactile feedback.
Precise Interactions with iRobota Mega and Facial Control Pad
The FaceWidgets system utilizes an iRobota Mega and a facial control pad to detect physical interactions. The control pad extends and retracts for optimal usage via a motor shield and stepper motors. This precise mechanism ensures that you can interact with the virtual widgets with ease and accuracy, making your VR experience more engaging and enjoyable.
Optimal Viewing Distance to Avoid Double Vision
To avoid double vision and ensure a comfortable viewing experience, the researchers behind FaceWidgets suggest displaying the virtual widgets at 20 cm from the eye positions. This distance allows users to access the interface as needed without straining their eyes or experiencing discomfort.
Innovative Interactions: Widget Canvas and Palm-Facing Gesture
FaceWidgets introduces two novel interactions that enhance the user experience in VR. The widget canvas allows users to manipulate widgets both physically and in the virtual world, providing a more intuitive and engaging way to interact with the environment. The palm-facing gesture enables users to access the interface without having to remove the HMD, making it convenient and seamless.
Applications for Video Playback and Smart Home Control
To showcase the versatility of FaceWidgets, the researchers developed two applications: a fixed-layout 360-degree video player and a contextual input for smart home control. These applications demonstrate the system’s potential for various use cases, from entertainment to home automation.
Participant Feedback and Transparent Hand Visualization
In an exploratory study, four hand visualizations were compared against the two applications. Participants considered the transparent hand as the most suitable, indicating its potential for enhancing the user experience in VR environments. Overall, participants responded positively to the FaceWidgets system, suggesting its potential for revolutionizing the way we interact with VR.
Bonus: The FaceWidgets system opens up exciting possibilities for VR gaming. Imagine playing a game where you can control your character’s actions and abilities using physical control panels attached to your HMD. This level of immersion could transform the way we experience VR games, making them more engaging and immersive than ever before.
FaceWidgets represents a significant step forward in the evolution of VR technology. By combining physical control panels with the virtual world, it enhances immersion, provides tactile feedback, and introduces innovative interactions that make VR experiences more enjoyable and intuitive. As the technology continues to evolve, we can expect to see even more innovative and groundbreaking applications for FaceWidgets in the years to come.
