My journey into this topic began while working on VR training simulators and a Mixed Reality prototypes at xrbootcamp.com , where users could train with a stopwatch. This experience taught me the importance of timing and synchronization in creating engaging and effective VR experiences. As a classical violinist, I’ve had the privilege of collaborating with award-winning stage directors like Stefan Huber and choreographers like Nici Grandison on multiple-art concert shows (check out our work at https://TerweysToechter.de ). Through these collaborations, I’ve gained many insights into the art of timing, where music, visuals, motion, and storytelling seamlessly interweave to create unique and captivating stage performances. Many of these techniques are transferable to the world of VR. My parents, who are graphic designers, have always emphasized the impact of visuals with the age-old adage, “An image is worth a thousand words.” In XR, we have many tools and solutions to create visual effects. Therefore, the second section of this article lists visual techniques.
My goal in writing this article is to bridge the worlds of my passions — music, VR technology, and visuals.
Cinematographic and storytelling methods
Time dilation and slow motion
Time dilation and slow motion are effective techniques in VR for creating a sense of time by manipulating the perception of time itself.
Time dilation and slow motion allow you to emphasize and draw attention to specific moments or actions within the VR experience. By slowing down time during crucial events, users can focus on the details and appreciate the visual and emotional aspects of these scenes. This can make these moments more impactful and cinematic.
Slow motion can make users feel more immersed in the virtual environment. It gives them a chance to explore and absorb the details of the VR world that might go unnoticed at regular speed. This deepens their connection with the experience and enhances the overall sense of time within the virtual world.
Time travel and flashbacks
Utilize time travel and flashbacks in VR to engage users with different eras, memories, and alternate realities, fostering intrigue, emotions, and discovery. Ensure seamless transitions between time periods by choosing appropriate interaction methods like portals, buttons, gestures, or gaze-based actions, aligning with the VR style and narrative context.
Time loop and repetition
Employ time loops and repetitions where users encounter recurring events in the virtual world. This can lead to challenging and captivating scenarios like puzzle-solving, escape attempts, or cycle-breaking. Implement time loops by scripting scene resets or using triggers. Be mindful of how time loops and repetition affect VR variety, progression, and user motivation, as these aspects should remain engaging and rewarding.
Temporal Progression
Storytelling and content progression can also create a sense of time. As users navigate through different scenes or scenarios, they feel as though they are moving through time.
Visual methods
Visual methods can create a rich sense of time within the virtual environment, enhancing the overall immersion and storytelling in VR experiences.
Changing Lighting and Dynamic Shadows
Altering lighting conditions within the virtual environment to mimic the progression of time convey the passage of time. For example, the simulation of a day-night cycle with changing sun positions, shadows, materials, and colors. Dynamic shadows can be used to indicate the position of the sun in the sky, thus giving viewers a sense of time. As the sun moves, shadows change accordingly.
Environmental Changes
Gradual changes in the environment, such as weather transitions (rainy to sunny) or seasonal changes (spring to winter), can indicate the passage of time. Weather and seasonal shifts can impact gameplay and interactions. For instance, in snowy terrain make te user move slower to impact the user’s perception of time.
Physics and Simulations
Realistic physics and simulations can help users feel the passage of time. Objects in the VR world can interact with each other and the environment based on physical laws. As time passes, these interactions evolve. For instance, falling leaves, a stack of books might topple over, water ripples may spread further, or a pendulum’s swing may gradually slow down, all of which provide visual cues to the passage of time.
Character Movements
Realistic physics can affect the movement and behavior of characters or entities within the VR world. Animate characters or objects to move in a way that suggests the passage of time. For instance, show characters aging or growing. Characters may tire over extended periods, slowing down or displaying signs of fatigue. This change in behavior communicates the progression of time and events.
Interactive Clocks and Timers
Incorporating visible clocks, timers, or calendar-like elements within the VR environment that users can observe and interact with let the users understand and perceive the current time.
Dynamic Objects
Objects that change with time, such as a wilting flower, melting ice, or burning candles, can be used to represent the passing of time.
Time-sensitive Events
Including time-sensitive, event-based elements that occur at specific times within the VR experience. For instance, fireworks at night or a sunrise event. Time-sensitive events help control the pacing and rhythm of the VR experience. They can introduce moments of calm, action, tension, or reflection at precise intervals, ensuring that users are consistently engaged and that the experience feels dynamic.
Auditive methods
Spatial audio is a powerful tool in VR animations for creating a sense of time and immersing viewers. It provides cues and context that help immerse users in the temporal aspects of the virtual environment.
Ambient Soundscapes
Creating realistic ambient soundscapes that change with the time of day or season. For example, birds singing in the morning, owls in the evening, the hum of insects at dusk, rustling leaves in the fall, the crunch of snow in winter, or the distant sounds of a festival during a particular season. These audio cues enhance the immersive experience and indicate time changes.
Dynamic Sound Effects
Implementing dynamic sound effects that reflect temporal changes, such as footsteps on different surfaces, varying wind speeds, or the flow of water, to simulate the changing environment as time progresses.
Time-Dependent Music
Using music or soundtracks that vary in style, tempo, and mood to match the time of day or the emotional tone of a particular VR scene. For example, calming melodies for sunrise and livelier tunes for daytime scenes.
Time-Triggered Sound Events
Triggering specific sound events at particular times within the VR experience to evoke the passing of time. This can include the ringing of an alarm clock in a morning scenario, church bells, or the distant sound of fireworks at night.
Character Dialogue
Having characters or NPCs (Non-Player Characters) engage in dialogue that references the time or reflects the progression of time.
Narrative Voiceovers
Implementing voiceovers or narration that explicitly mentions the time, the day of the week, or the season. This can help provide context for the viewer.
Temporal Transition Effects
Applying audio effects like warping or echoing to create a dreamlike sensation when transitioning between different times or memories, or from the past to the present in a historical VR experience.
Temporal Music Leitmotifs
Creating recurring musical themes or leitmotifs that are associated with specific periods, events, or characters within the VR narrative.
Haptic effects
Haptic effects should complement other sensory cues and align with visual and auditory elements to create a holistic experience that effectively conveys the passage of time in VR.
Temporal Pulsing
By applying haptic pulses at regular intervals, you can create a sense of rhythm or a metronome-like effect that conveys the passage of time. This can be used to make users feel time passing in a measured way.
Duration-Based Feedback
Haptic feedback can be tied to the duration of specific events or actions within the VR experience. For example, a short vibration when a timer reaches one minute and a longer vibration when it reaches an hour.
Clock-Like Vibrations
By simulating clock-like ticking or chimes through haptic sensations, users can feel the passage of time more tangibly. Each tick or chime can represent a unit of time.
Temporal Alerts
Implement haptic alerts to remind users of scheduled events or temporal milestones, such as appointments or time-sensitive tasks.
Real-Time Interactions
Haptic feedback can be used to simulate the feel of real-time interactions, such as typing on a keyboard,
Varying Intensities
Haptic feedback can change in intensity to represent the acceleration or deceleration of time. For instance, the haptic sensation can become stronger as time speeds up and weaker as it slows down.
