I'm not sure about Hong Kong, but the PB/5[0] has tactile feedback in addition to audio. You can put your hand on it and feel the clicks.
Slow clicks help deaf users locate the button; fast clicks mean it's safe to cross; silence means you shouldn't enter the crossing because there's not enough time left.

- rmccue 3y agoThey’re almost perfect, but from what I’ve observed, there are two variants: one where the button sticks out, and another where the button is surrounded by a lip. I absolutely detest the lip variant. It makes it impossible to slap the button with an open palm, requiring an actual push instead. Particularly with the pandemic, they were near impossible to activate with an elbow. So close to perfection and yet so far… That said I now have to deal with the terrible British ones, and the attached signals that are supposedly safer - they’re on the same device as the button, supposedly forcing you to look at them and face the traffic. In practise, the inconsistency of whether there’s a crossing indicator on the other side of the road or not means I rely solely on sound cues. If everyone can just adopt the PB/5, even with the atrocious lip, the world will be a better place.
