What HandMol Offers

HandMol delivers immersive molecular graphics and modeling, enabling users to interact with atoms and molecules using their hands. The application supports real-time physics simulations and allows for collaborative interactions, accommodating up to two users engaging with a molecular system simultaneously.

For a visual representation, consider the following screenshot, where the grey hands belong to one user while the green hands belong to another in the same VR session:

Ideal for VR but Accessible on All Devices

HandMol is primarily designed for use with VR headsets, particularly those from the Meta Quest line, which are priced starting at USD 350. However, due to its web-based design, it is compatible with various devices, including smartphones. Thus, even without a VR headset, users can still benefit from the application.

The following image demonstrates the app functioning on a smartphone, and with VR goggles, it provides an immersive experience comparable to that of high-end VR headsets, albeit without hand-tracking capabilities:

Transforming Chemistry Learning in Classrooms

HandMol aims to replace outdated two-dimensional representations that inadequately convey the three-dimensional nature of molecular structures. This tool facilitates a more interactive learning environment, fostering real-time discussions and hands-on manipulation of molecular models, thus breaking free from the constraints of traditional 2D images and static plastic modeling kits.

Consider the classroom of the future, where teachers and students can collaboratively explore molecular models, enhancing their understanding of complex concepts.

Concrete Applications of HandMol

HandMol comes equipped with various examples to illustrate fundamental chemistry principles, such as bonding, molecular geometries, isomerism, and more. Here’s a preview of the examples available within the tool:

Some specific applications of HandMol include:

• Virtual Modeling Kit: This hands-on experience enhances understanding of molecular geometry, allowing users to assemble molecules atom by atom while learning about bond lengths and angles.
• Exploring Conformations and Isomerism: HandMol makes it easy to visualize molecular conformations, allowing students to engage with concepts like flexibility in aromatic versus non-aromatic rings.
• Simulating Chemical Reactions: The application enables simulations of dynamic chemical processes, providing a virtual laboratory experience.
• Understanding Biological Structures: Users can explore complex biological structures, such as proteins and DNA, in a 3D space, facilitating a deeper understanding of these intricate systems.

Beyond the Classroom: Self-Learning and Research Potential

HandMol's easy accessibility means it is not confined to formal education; students can use it at home for self-study, potentially utilizing its collaborative features to consult with peers online. For researchers, this tool opens new pathways for collaborative exploration and molecular simulation setup, revolutionizing how they engage with molecular sciences.

Exploring AR Capabilities

While VR offers immersive experiences, augmented reality (AR) may provide a more connected learning environment, allowing students to maintain visual contact with their peers and instructors. HandMol has experimental modes that utilize AR, available on both VR headsets and smartphones:

Free Access to HandMol

As a prototype, HandMol is free to use at https://go.epfl.ch/handmol, with no registration required. Detailed instructions for various user sessions are provided in the accompanying preprint.

Future Outlook and Innovations

As we look toward the future of education and research, HandMol exemplifies the potential for interactive simulations to enhance learning across various scientific disciplines. Future applications could extend to VR environments for physics experiments, biology exploration, and geometric modeling, inspired by HandMol's concepts.
