Customisable. All M-Dial™ functionality is completely customisable using the Altar II companion app. 可定制：所有 M-Dial™ 功能均可通过 Altar II 配套应用程序完全自定义。
Haptic Feedback: Feels like an epiphany. Harmonic Synthesiser™ enables crisp, subtle, expressive haptic feedback. 触觉反馈：感觉如醍醐灌顶。Harmonic Synthesiser™（谐波合成器）可提供清脆、细腻且富有表现力的触觉反馈。
Harmonic Synthesiser™ enables new ways to interact with your computer through gentle, delightful haptic feedback. It enhances the typing experience and is engineered alongside M-Dial™ for real-time simulated ticks. Harmonic Synthesiser™ 通过温和、愉悦的触觉反馈，开启了与电脑交互的新方式。它增强了打字体验，并与 M-Dial™ 协同设计，可实现实时的模拟滴答声。
It also gives tactile feedback about the state of Altar II, like when it wakes and connects to your computer. 它还能提供关于 Altar II 状态的触觉反馈，例如唤醒和连接电脑时。
Novel interactions. Holding a modifier key gives a smooth, oscillating hum, and a gentle pop lets you know when a shortcut has been completed. 新颖交互：按住修饰键会产生平滑的振动嗡嗡声，轻微的“砰”声提示你快捷键已完成。
Subtle real-time feedback. Altar II taps you when you receive notifications, reminders, or alerts from your Mac. 细腻的实时反馈：当你收到来自 Mac 的通知、提醒或警告时，Altar II 会轻触提醒你。
Fully configurable. Tune intensity and behaviour of haptic feedback in the EMO app. 完全可配置：在 EMO 应用程序中调节触觉反馈的强度和行为。
Audio: A high fidelity speaker built into Altar II enables subtle audio feedback — like wake sounds, and charging chimes. 音频：Altar II 内置高保真扬声器，可提供细腻的音频反馈，如唤醒音和充电提示音。
Native macOS App: Made for Mac. Fully native. A lightweight, delightfully designed app, written in Swift and crafted specifically for macOS. 原生 macOS 应用：为 Mac 而生。完全原生。这是一款轻量级、设计精美的应用程序，使用 Swift 编写，专为 macOS 打造。
You’re in control. Customise Altar II by changing key bindings, M-Dial™ behaviours, backlight, haptic and audio levels. 掌控自如：通过更改键位映射、M-Dial™ 行为、背光、触觉和音频级别来定制 Altar II。

Backlight: Follow the light. NiteLite™ preserves night vision, reduces eye strain and helps you sleep better. 背光：追随光芒。NiteLite™ 可保护夜视能力，减少眼睛疲劳，并帮助你睡得更好。
Here when you need it. NiteLite™ only activates in low ambient lighting conditions, such as at night. 按需开启：NiteLite™ 仅在环境光线较暗（如夜晚）时才会激活。
Sleep better. NiteLite uses a long-wavelength amber-red light that won’t affect your body’s circadian rhythm, meaning you can sleep better at night. 睡得更好：NiteLite 使用长波长琥珀红光，不会影响人体的昼夜节律，这意味着你晚上可以睡得更好。
See clearly. NiteLite™ reduces eye strain and preserves your eyes’ natural night vision. 看得清晰：NiteLite™ 可减少眼睛疲劳并保护眼睛的自然夜视能力。
Inertial Damper: Sounds divine. A dual layer Inertial Damper™ provides understated acoustics and responsive key feedback. 惯性阻尼器：声音美妙。双层惯性阻尼器（Inertial Damper™）提供了低调的声学效果和灵敏的按键反馈。
Floating foundation. The Inertial Damper™ system is composed of dual layers: A silicone membrane between the logic board and monobody, and an oversize elastomer footpad below. This system suspends the typing platform for total acoustic and vibration isolation. 悬浮基座：惯性阻尼器系统由双层组成：逻辑板与一体化机身之间的硅胶膜，以及下方超大的弹性脚垫。该系统将打字平台悬浮起来，实现了完全的声学和振动隔离。
Ergonomics: Sacred geometry. A super slim frame ensures a comfortable, ergonomic typing position. 人体工程学：神圣几何。超薄框架确保了舒适、符合人体工程学的打字姿势。
Standard mechanical keyboard: Typical mechanical keyboards have a tall leading edge that requires wrist extension when in use. Over long periods this can cause strain. 标准机械键盘：典型的机械键盘前缘较高，使用时需要手腕过度伸展。长时间使用会导致疲劳。
Altar II: With a sub 5mm thin chassis, wrist extension is minimal when using Altar II. This reduces likelihood of carpal tunnel syndrome or repetitive strain injuries. Altar II：机身厚度不足 5 毫米，使用 Altar II 时手腕伸展极小。这降低了患腕管综合征或重复性劳损的风险。
