KHAROS is an experimental concept exploring how sound alone can drive a fully immersive interactive experience. Designed for mobile and built around binaural audio, the project removes visuals entirely, placing the player in complete darkness and forcing them to rely on sound, movement, and instinct.
A horror experience crafted entirely from sound.
Rather than presenting horror through imagery, KHAROS focuses on perception — how players interpret space, danger, and presence when they can’t see. The result is a more personal and psychological form of interaction, where tension is created through uncertainty and imagination.
The core idea behind KHAROS is simple: removing visual feedback increases immersion. Without a screen to rely on, players become more aware of subtle cues — distance, direction, rhythm, and movement. Every sound becomes meaningful, and every action has consequence.
Using spatial audio, the environment is constructed as a three-dimensional soundscape. Footsteps, echoes, distant movement, and environmental hazards are positioned around the player, allowing them to navigate purely through listening. The experience responds dynamically to movement, using device sensors to translate physical motion into in-game actions. This creates a system where behaviour directly affects outcome. Moving too quickly, hesitating, or reacting unpredictably can change how the environment responds. Instead of scripted scares, tension builds through interaction — players are not just experiencing fear, they are influencing it.
KHAROS also explores how progression and difficulty can be communicated without visual cues. Different entities and hazards are defined by distinct audio signatures, allowing players to learn and adapt over time. Subtle changes in tone, rhythm, and intensity guide decision-making, replacing traditional UI elements with intuitive feedback.
A world that evolves with the player.
The concept introduces multiple play styles, including a more forgiving progression-based mode and a high-stakes mode where failure resets the entire experience. This reinforces the psychological aspect of the design, where risk and consequence become part of the core interaction. At its core, KHAROS is a study in sensory design — how sound, space, and interaction can replace visuals entirely while still delivering a coherent and engaging experience. It challenges conventional approaches to both game design and user interfaces, showing how removing elements can sometimes create something more immersive.
The project highlights how digital experiences don’t have to rely on screens alone. By focusing on alternative forms of interaction, KHAROS explores new ways to engage users, build tension, and create meaning through design.
This is not just a game concept — it is an exploration of how sound can become the primary interface.
