帮助视障主人察觉导盲犬状态变化的穿戴设备概念A wearable concept that helps visually impaired owners notice changes in their guide dog

以穿戴形态、非视觉反馈与主人主导的决策，连接日常导盲出行。A daily guiding concept linking wearable form, nonvisual feedback and owner-led choices.

问题定义The question

如何让导盲犬的状态更易被察觉，并把决定权留给主人？How might changes in a guide dog’s state become easier to notice, while leaving decisions with the owner?

导盲犬长期在拥挤与噪声中工作。压力迹象（舔鼻、耳朵后压、尾巴下垂）多是视觉信号，视障主人很难察觉，而导盲犬状态下降又直接影响主人的出行安全。Guide dogs work in crowds and noise. Signs of stress—nose licking, flattened ears, a lowered tail—are visual, so a visually impaired handler can miss them, and a decline affects the handler’s own safety.

  1. 关键取舍 01Key decision 01

    为什么选择圆形单一按压入口，而不是带状双端结构？Why a round housing with one press target, rather than a band with paired ends?

    主人要靠触摸找到设备。圆形外壳只有一个中央按压目标，更容易凭手感找到，体积也集中在背带局部；带状双端结构触达和安装都更复杂。Handlers find the device by touch. The round housing has one central target that is easy to locate by hand and a compact footprint on the harness; the paired-end band is harder to reach and to mount.

    代价Trade-off内部空间更有限，部件必须排布得更紧凑。Less internal space, so the parts must pack tightly.

  2. 关键取舍 02Key decision 02

    为什么由主人决定，而不是设备自动干预？Why let the owner decide, rather than intervening automatically?

    压力迹象很难被准确感测，自动干预可能误判。设备只提示「状态有变化」，由主人检查后决定是否休息或调整路线。Stress signs are hard to sense reliably, and automatic intervention could misjudge. The device only signals that something has changed; the owner checks and decides whether to rest or reroute.

    代价Trade-off设备不会主动安抚导盲犬，所有处理都要等主人判断。The device never calms the dog on its own; every response waits for the owner.

深度访谈In-depth interviews
受访者 A · 导盲犬训导员Interviewee A · guide-dog trainer
“智能抗命最难。过马路时主人说「走」，但有车开过来，狗得自己决定停下。这是很大的压力来源。”“Intelligent disobedience is the hardest. At a crossing the owner says ‘go’, but a car is coming, and the dog has to decide to stop on its own. That is a huge source of stress.”
“我们尽量模拟真实环境，但真实的城市比任何训练场都复杂得多。”“We simulate real environments as best we can, but a real city is far more complex than any training ground.”
受访者 B · 视障导盲犬使用者Interviewee B · visually impaired handler
“我知道它会累，但很难分清是身体累还是心里紧张。它不会说话，我只能靠它的动作和呼吸来判断。”“I know it gets tired, but it’s often hard to tell whether that is physical fatigue or stress. It can’t speak, so I can only judge by its movement and breathing.”
“早高峰的公交太挤，它没地方趴下，只能站着，还会被包和脚碰到。我能感觉到它在忍。”“At rush hour the bus is so crowded that it has no room to lie down. It has to stand, and gets knocked by bags and feet. I can feel it putting up with it.”
