The offline desk gadget that actually got me to sit up straight

这款让我真正坐直的离线桌面小工具

Working from home has its own perils. Pets can be demanding, your back aches from hours at a desk, or you simply forget to move. There are a few apps that nudge you to move around or indicate that you’re not sitting in an ideal position, but they’re easy to dismiss. I’ve spent the better part of a decade at a home desk, iterating on the setup as I go — gaming chair, lumbar support, the works. None of it guarantees good posture. Then I came across Isa, a desk device from German startup Deep Care that takes a different approach entirely. It tracks posture, hydration, light, sound, and movement. And it does all of it without a camera or an internet connection, which, in an era of always-on surveillance, is a meaningful differentiator. Here’s how it works and what’s inside.

居家办公有其自身的风险。宠物可能会捣乱，久坐会导致背部酸痛，或者你只是单纯地忘了活动。市面上有一些应用程序会提醒你走动，或者提示你的坐姿不理想，但这些提醒很容易被忽视。我在居家办公桌前度过了近十年，不断改进我的设备——电竞椅、腰部支撑，应有尽有。但这些都无法保证良好的坐姿。后来，我发现了来自德国初创公司 Deep Care 的桌面设备 Isa，它采取了完全不同的方法。它能追踪坐姿、饮水量、光线、声音和运动情况。最重要的是，它无需摄像头或互联网连接即可完成所有这些工作，在当今这个全天候监控的时代，这是一个非常有意义的差异化优势。以下是它的工作原理和内部构造。

Isa has a 5.5-inch IPS HD screen and looks like a table clock. It is powered by USB-C; the company supplies a power unit with it, but you can use any of your existing chargers too, as it has a power consumption rating of roughly 2.45W. The key sensor for the device is the Time-of-Flight (ToF) 3D depth sensor on the front — the same technology used in facial recognition and some smartphone cameras — that tracks posture and movement. It also enables beta features, such as counting the number of times you’ve had water or other liquids. The company said that the sensor works in the range of 0.15 meters to 1.8 meters. That means if the device is sitting on your desk, it can measure your movement, even when you stand up and move about. It also packs several other sensors: a ToF 1D sensor, a gyroscope, a barometer, a light sensor, a sound level sensor, a CO₂/VoC sensor, and a temperature and humidity sensor.

Isa 配备了一块 5.5 英寸的 IPS 高清屏幕，看起来像个台钟。它通过 USB-C 供电；公司随附了一个电源适配器，但你也可以使用现有的任何充电器，因为它的功耗约为 2.45W。该设备的核心传感器是正面的飞行时间（ToF）3D 深度传感器——这与人脸识别和某些智能手机摄像头使用的技术相同——它负责追踪坐姿和运动。它还支持一些测试版功能，例如统计你喝水或其他液体的次数。公司表示，该传感器的有效工作范围为 0.15 米至 1.8 米。这意味着如果设备放在桌面上，即使你站起来走动，它也能测量你的运动情况。它还集成了其他几个传感器：ToF 1D 传感器、陀螺仪、气压计、光线传感器、声级传感器、二氧化碳/挥发性有机化合物（CO₂/VoC）传感器以及温湿度传感器。

Getting started is straightforward — the device asks for a few details about you and your work routine. I found it strange that there was no option to set the device to India time (or any other Asian time zone). The company said Isa currently supports only EU and US time zones. Fair enough for now — but broader time zone support, or even a simple world clock, feels like a basic expectation for a desk device. On the screen, Isa displays your posture with a squircle (a rounded square) ring that fills or empties based on how well you’re sitting, while a water-tank-style widget tracks your drinking. If you are not sitting in the correct posture, the indicator will turn yellow. The Apple Watch-style ring is a surprisingly effective nudge — when I see yellow or red, I straighten up almost instinctively. The device vibrates to alert you if you’ve been slouching for too long, and I’m okay with that kind of mild shaming. That alert also indicates if you are leaning far too forward or back and helps you correct your stance.

上手过程很简单——设备会询问你的一些个人信息和工作习惯。我觉得奇怪的是，它没有设置印度时间（或任何其他亚洲时区）的选项。公司表示，Isa 目前仅支持欧盟和美国时区。目前来说尚可接受，但对于一款桌面设备而言，支持更广泛的时区，甚至只是一个简单的世界时钟，都是基本预期。在屏幕上，Isa 会用一个圆角矩形环来显示你的坐姿，该环会根据你的坐姿是否标准而填充或清空，同时还有一个水箱样式的小部件来追踪你的饮水情况。如果你坐姿不正确，指示灯会变黄。这种类似 Apple Watch 的圆环提醒效果出奇地好——当我看到黄色或红色时，几乎会本能地坐直。如果你长时间弯腰驼背，设备会震动提醒你，我并不介意这种轻微的“羞辱”。该提醒还会指出你是否过度前倾或后仰，从而帮助你纠正姿势。

A similar widget tracks movement, and if you have been stationary for a while, Isa suggests you get up, with on-device guided exercises to follow. When you return to your desk after a break, the movement tracker resets. Deep Care chose not to include a camera, which helps with privacy, but it comes with trade-offs. If a bottle or some other object sits between you and the sensor, it may read that as a person and log you as stationary. Pets or housemates passing by can trigger the sensor, too. Isa usually figures out that you’ve stepped away and goes to a digital clock display, but I would have liked a manual button to tell it I’m not at the desk so it stops tracking. Because of the sensor-only approach, the device occasionally told me I’d been stationary for too long when I’d been sitting for under half an hour. These are minor inconveniences. On balance, the device made me check my posture more often than I used to, and the exercise suggestions are truly useful.

类似的小部件可以追踪运动情况，如果你长时间保持静止，Isa 会建议你站起来，并提供设备内置的引导式锻炼。当你休息后回到桌前，运动追踪器会自动重置。Deep Care 选择不安装摄像头，这有助于保护隐私，但也带来了一些权衡。如果瓶子或其他物体挡在你和传感器之间，它可能会将其误读为一个人，并将你记录为静止状态。宠物或室友经过时也会触发传感器。Isa 通常能识别出你已经离开并切换到数字时钟显示，但我更希望有一个手动按钮来告诉它我不在桌前，以便停止追踪。由于仅依赖传感器，该设备有时在我坐下不到半小时时就提示我静止时间过长。这些都是小麻烦。总的来说，这款设备让我比以前更频繁地检查自己的坐姿，而且锻炼建议确实很有用。

To process all these features, the device uses a quad-core 2 GHz processor. The device can connect to Wi-Fi for software updates, but you can turn it off at any time. Deep Care was founded by three former Bosch employees and initially sold Isa directly to businesses. It recently expanded to consumers — a shift that signals confidence in the retail market for workplace wellness hardware, and a test of whether a subscription model layered onto premium hardware can find a mainstream audience. Isa is priced at €299 ($354) with two subscription tiers. The core plan (€4.99 per month) gives you access to posture tracking, healthy sitting habit tracking, drinking habit detection, and its exercise library. The Pro plan (€7.99 per month) lets you track light, noise, and CO2 levels for a healthy working environment.

为了处理所有这些功能，该设备采用了四核 2 GHz 处理器。设备可以连接 Wi-Fi 进行软件更新，但你可以随时关闭它。Deep Care 由三名前博世员工创立，最初直接向企业销售 Isa。最近，它扩展到了消费者市场——这一转变表明了其对职场健康硬件零售市场的信心，也是对“高端硬件+订阅模式”能否获得主流受众的一次测试。Isa 的售价为 299 欧元（354 美元），并提供两个订阅等级。核心计划（每月 4.99 欧元）提供坐姿追踪、健康坐姿习惯追踪、饮水习惯检测及其锻炼库。专业计划（每月 7.99 欧元）则允许你追踪光线、噪音和二氧化碳水平，以营造健康的办公环境。

The company plans to use Isa’s sensor suite to venture into mental health-related tracking. It claims that by using signals like posture, head movement, and chest movement, the device can measure breathing patterns. Plus, paired with environmental data like noise, light levels, and CO2 level, the company wants to introduce a stress-related score. Even if you skip the mental health features, Isa is a solid device for anyone serious about posture and movement. It isn’t cheap, and the subscription adds to the long-term cost. But if you or someone you know works from home and has been meaning to do something about their desk habits, it’s one of the more thoughtful options out there.

该公司计划利用 Isa 的传感器套件进军心理健康相关的追踪领域。它声称，通过利用坐姿、头部运动和胸部运动等信号，该设备可以测量呼吸模式。此外，结合噪音、光照水平和二氧化碳水平等环境数据，公司希望引入压力相关评分。即使你跳过心理健康功能，对于任何认真对待坐姿和运动的人来说，Isa 仍然是一款可靠的设备。它并不便宜，订阅费用也增加了长期成本。但如果你或你认识的人居家办公，并且一直想改善办公习惯，那么它是目前市面上比较贴心的选择之一。
