Core Values

Unbound the UI, Unleash the UX.

Flexible

Responds flexibly to diverse environments. Open structure that seamlessly integrates with everyone. Delivers tailored experiences optimized for each context.

Adaptive

Continuously adapts to evolving technology. Actively coordinates rather than passively follows. Pursues ongoing innovation through continuous evolution.

Expandable

Expands into new customers, contexts, and meanings. Builds new ecosystems. Offers an expanded, connected service experience.

Interface

This is the central app installed on the vehicle's main display. Built on Android Auto, it enables smooth management of guest device connections within the car. The host can accept or reject connection requests, configure detailed permissions for each guest, and coordinate the overall UI chain across devices.

FX UI

A dedicated app for passengers' personal smartphones, serving as the primary interface for the FluidX platform. With no complex setup required, any passenger can intuitively interact with the vehicle’s system. Simply launching the app allows users to control climate settings, media playback, and distributed UIs directly from their own devices.

FX UI

An app that enables FluidX’s signature Multi-View Interface experience. Passengers can flexibly switch between interior and exterior camera views, see one another across seats, and control features like air conditioning and media playback—all within a unified interface. Each user accesses a personalized perspective, supporting fluid interaction and shared awareness across multiple devices.

FX UI

An interactive multiplayer game designed specifically for the FluidX multi-device environment. This reimagined version of the classic Tic Tac Toe allows passengers to play simultaneously using their own devices. More than just a simple game, it serves as a prototype demonstrating how shared interfaces can foster connection and engagement among passengers during the ride.

Technology

Fluid X is a next-generation mobile platform technology that enables mobile apps to transcend the limitations of the single-device paradigm. Without requiring any modification to the original app code, Fluid X allows applications to seamlessly expand across multiple smart devices — offering the world’s first and most advanced multi-device solution.

Fluid X’s UI-Chain Distribution enables a sequence of user interfaces to be delivered step-by-step across guest devices. Each interface is triggered by user input on the previous step, allowing guests to interact with the UI sequentially and independently. This ensures smooth task progression across devices while preserving continuity — without requiring any intervention from the driver or the main host device.

UI 1

Fluid X could evolve to support Contextual UI Accessibility, enabling different levels of UI distribution based on the user's social or situational context. This would allow interface access to be tailored to each context, enhancing both relevance and privacy.

UI 1

Our Technology is ready to integrate with GM vehicles using Android Automotive 14. It runs existing Android apps without any code modification and connects seamlessly to user smartphones through a single proxy app using Wi-Fi Direct. Optimized for various devices like Google Pixel, Samsung Galaxy, and tablets, Fluid X enables smooth multi-device interaction within the car environment.
