13 We must choose what to make Can predict nothing Buy more tickets * Driven by synthesis Can predict something Place bets based on previous form * Driven by design Chemical space is huge. Use data, algorithms and IT: faster, cheaper and better

14 Molecules are 3D objects All molecules ranging from structurally simple drugs like aspirin to complex systems like proteins to the famous DNA double helix are 3D objects. visualizing and interacting with molecular models is part of a drug designers day job Knowledge about their 3D structure is important in most stages of drug discovery

Stand-alone Rasmol, PyMol, VIDA and now web-based systems Jmol, AstexViewer,

17 3D Molecular Viewing Tools With the rise of efficient computers, the focus switched from physical representations to computer generated models. Stand-alone Rasmol, PyMol, VIDA and now web-based systems Jmol, AstexViewer, iview. an important innovation here was the ability to display stereoscopic 3D views.

18 Virtual reality for Drug Designers But even with the stereo, traditional visualizers just show molecules in front of you; with VR a drug designer can enter a protein-ligand complex. Surprisingly few examples of VR in drug design

19 Molecular Rift The first easily accessible Virtual Reality tool for Drug Design Molecular Rift creates a VR environment using Oculus Rift goggles. Users can interact with molecules through gestures

20 Details Oculus Rift goggles are used to create to the VR environment. Gesture recognition (interaction) MS Kinect (v1) Leap Motion (v2), Development: Unity game engine (MS Kinect v2) Leap Motion SDK Oculus Runtime OpenBabel open source cheminformatics tool-kit. Programming: Windows and mainly C#

21 Gesture-Based Interactions Traditional input devices (mouse and keyboards) are not ideal with goggles Oculus Rift Molecular Rift v1 MS Kinect (X-box) Molecular Rift v2 Leap Motion and controller

Compare with the technology evolution to that which occurred for normal phone calls:

25 More Useful? Although cool, is Molecular Rift more useful than traditional molecular visualizers? Compare with the technology evolution to that which occurred for normal phone calls: Before we called, we now use FaceTime/Skype to see that we are talking to. communication In essence, it is almost the same, but a new and improved experience.

26 What s the difference? 3D viz In essence, it is almost the same, but a new and improved experience it s more efficient.and drug design is not all that rational, there s a portion of creativity and VR comes with an inherent wow this is cool!

27 If only people tried before asking Focus groups red is good [here]

VR Predictions Smartphones and Google Cardboard-like tech will conquer VR. Mobile apps enables VR experiences without having to invest into extensive systems.

33 VR Predictions Smartphones and Google Cardboard-like tech will conquer VR. Mobile apps enables VR experiences without having to invest into extensive systems. Does not need a high-end PC to run applications. It s truly mobile (no wires) Hardware is cheap, if not free (most people already have a smartphone). Performant Google Daydream, Samsung GearVR VR is great for many things training, real estate, phobias, education,

34 VR in Chemistry Education* Vision is to engage more students in chemistry using virtual reality. Giving us more drug designers? * A former student and I started a separate EdTech VR Company last year
