# bHaptics Player for iOS

Apr 2024 · Auejin Ham , Laeyoung Chang

- **What** — An iOS application (SwiftUI) that drives bHaptics vests and gloves.
- **Why** — To feel what happens in a game on your body, something has to sit between the PC or PSVR title and the hardware in real time.
- **How** — It finds supported titles on the same Wi-Fi network by itself, takes their events, and relays them over BLE in under 20 ms, alongside firmware update (DFU) and account flows.
- **New** — It ships with a Swift SDK folding device state and account state into the SwiftUI lifecycle, so the app and the SDK share one state machine.

## bHaptics Player: iOS Application for bHaptics Tactile Device Integration

## Abstract

This is the primary project I've dedicated the most time to during my tenure at bHaptics.

Developed an iOS application for bHaptics tactile device users that enables real-time haptic feedback from PC and PSVR games via Bluetooth connectivity. The application automatically detects bHaptics-supported games running on PC or PSVR connected to the same Wi-Fi network as the mobile device. It facilitates communication between the game and tactile devices with less than 20ms latency.

## Key Features & Technical Contributions:

- Implemented real-time motor intensity testing interface for tactile devices
- Designed an interactive feature allowing users to draw curves that generate corresponding haptic sensations
- Built device management interfaces including battery monitoring and firmware information configuration
- Engineered firmware update functionality (DFU) with seamless user experience
- Created user profile management and comprehensive onboarding flows

## Architectural Achievements:

- Developed a Swift-based SDK that abstracts BLE device communication and user account information
- Implemented state management system that synchronizes real-time device states with SwiftUI lifecycle events
- Integrated Firebase Remote Config and Google Analytics for user experience analysis and optimization
- Accelerated development by creating SwiftUI extensions for company design conventions (color palettes, font faces, buttons, input fields)
- Designed and implemented custom UX components based on HCI principles, including Snapping Closed-Range Slider and Rotating Carousel View

## Impact:

The application currently has over 8,700 downloads with more than 400 active users according to Google Analytics.
