上街去 / Carry the Cosmos

我选择的 Human Movement 场景，是一个人移动过程中的间隙。

The Human Movement scenario I have chosen is a pause within a person's movement.

它可能发生在散步途中、等待的时候，或走累之后的一次停留。人暂时没有明确目标，也没有什么必须完成的事情，只是在那里，发呆、观察，或者带着尚未整理好的情绪。

It might happen during a walk, while waiting, or when stopping to rest after growing tired. For a moment, there is no clear destination and nothing that must be done. A person is simply there: daydreaming, observing, or carrying feelings they have not yet made sense of.

这些空白的间隙里，也许脆弱，也许内心不稳定，也许百无聊赖，但非常迷人。它的迷人，在于人性在这些时刻产生着微妙的变化和移动。

In these empty intervals, we may feel vulnerable, unsettled, or utterly bored. Yet there is something deeply compelling about them: the subtle shifts and movements in our humanity during these moments.

这些时刻难以被描述，只能被感知，言语会让感知生锈。

These moments are difficult to describe. They can only be sensed. Words can make perception rust.

我关注的是：在这样的片刻里，人如何重新感到自己的身体、身边的环境，以及自己与世界之间的联系。产品如何轻轻参与其中，为尚未成形的感受保留空间。

What interests me is how, in such moments, a person might become aware again of their body, their surroundings, and their connection to the world. How might a product participate gently, leaving room for feelings that have yet to take shape?

在这个项目中，我将 Flâneur 理解为一种允许偶遇的漫游状态。人可以偏离路线，可以停下来，也可以暂时没有目的。而 Aha Moment，是一次很轻的觉察：

In this project, I understand the Flâneur as a way of wandering that leaves room for chance encounters. A person can stray from a route, stop, or have no destination for a while. An Aha Moment is a quiet realization:

一个小动作，可以得到回应；一个个普通的地方，也可以与自身产生关联。

A small gesture can receive a response. An ordinary place can become personally meaningful.

我希望把这样的体验整合进「上街去」。需要解决的设计问题是：在短暂停留中，如何让人通过身体动作参与互动、获得回应，同时保留观察、等待和随时结束的选择。

I want to bring these experiences into Carry the Cosmos (上街去). The design question is this: during a brief pause, how can people interact through bodily movement and receive a response, while retaining the choice to observe, wait, or end the interaction at any time?

手机感知身体动作与周围空间，结合情境与时序提供反馈。

The phone senses bodily movement and the surrounding space, then uses context and timing to provide feedback.

一种相遇，是让一只数字小鸟落在掌心。

One encounter begins with a digital bird landing in a person's palm.

人伸出手并停稳，小鸟靠近、落下，随手指与支点的变化调整动作。人可以与它玩一会儿，也可以保持不动，观察它停栖。等待也是互动的一部分。

A person offers a hand and holds it steady. The bird approaches and lands, adjusting its movements as the fingers and available perching points change. The person can play with it for a while, or remain still and watch it perch. Waiting is also part of the interaction.

这段体验由视觉感知、规则引擎与动作表现共同构成。手机端通过 Vision 识别手部关键点；规则引擎结合支点位置、动作持续时间与追踪状态，判断小鸟何时靠近、落下、换位或离开；已有的多方向动作素材呈现这些行为。

This experience brings together visual sensing, a rule engine, and animation. On the phone, Vision detects hand keypoints. The rule engine considers perch position, action duration, and tracking status to determine when the bird approaches, lands, changes position, or leaves. Existing animations in multiple directions bring these behaviors to life.

我尤其关注时间与识别误差的处理。短暂遮挡时，小鸟可以悬停等待；改变手指时，它通过飞行与落下转移支点；手保持稳定时，它也能停栖，偶尔转头张望。引擎保留当前互动状态，让连续的互动能够容纳短暂的识别误差。

I pay particular attention to timing and recognition errors. During a brief occlusion, the bird can hover and wait. When the fingers change position, it flies and lands to move between perching points. When the hand remains steady, it can stay perched, occasionally turning its head to look around. The engine retains the current interaction state, allowing a continuous experience to accommodate brief recognition errors.

另一种相遇，是在眼前种下一株数字植物。

Another encounter begins by planting a digital plant in the space before you.

人选择地面，种下植物，观察枝干、叶片与花朵逐渐展开。原本经过的地点，因为这次种植与观察，与人的停留建立联系。

A person chooses a spot on the ground, plants something, and watches its stems, leaves, and flowers gradually unfold. Through this act of planting and observation, a place they might otherwise pass through becomes connected to their pause.

ARKit 提供地面感知与空间追踪。系统确认稳定落点后，通过规则控制植物的生长节奏，并在追踪中断时暂停。植物固定在眼前的空间里，人可以改变角度、绕着观察，让身体的移动继续参与互动。

ARKit provides ground-plane detection and spatial tracking. Once the system confirms a stable placement, rules control the pace of growth and pause it when tracking is interrupted. The plant stays anchored in the space in front of the person. They can change their viewing angle or walk around it, allowing bodily movement to remain part of the interaction.

植物的选择与日常行走关联。「上街去」初始提供六种可种植的植物。此后，每累计一万有效步数，人就能从其余植物中自由选择一种，加入植物库。步数可以跨天积累，解锁后的植物可以反复种植。

Plant choices are connected to everyday walking. Shangjiequ initially offers six plants. For every 10,000 valid steps accumulated after that, a person can freely choose one of the remaining plants to add to their collection. Steps can accumulate across days, and unlocked plants can be planted again and again.

目前，产品已支持由世界模型根据地点照片生成三维场景，并从地图回访。我计划独立保存植物及其位置，并关联地点，让人回访时再次看到当时种下的植物。

The product already supports generating 3D scenes from photos of a place using a world model, and revisiting those scenes from the map. I plan to store plants and their positions separately and link them to places, so that people can see what they planted when they return.

这就是我重新定义的 Human Movement ，我认为意义存在于空白与间隙处。

This is my redefinition of Human Movement. I believe meaning exists in the empty spaces and intervals.
