We revisit the concept of a 'gesture' and discuss it, in particular, in the context of 3D interaction. We argue that one should distinguish between postures, quasi-postures, and gestures and that the first two should be (and are currently) preferred in 3D interfaces for directly-manipulative interaction with the environment in user-maintained modes. In scientific visualization we saw use cases of quasi-postures, suggesting that they are one way to re-use the same input space in order to facilitate several means of exploration.
