Nuance of ともなく / ともなしに

The key nuance is absence of deliberate intent or conscious focus.

For example:

• When you use 見る(みる)ともなく, you are not staring with a plan — you just happen to be looking, perhaps while your mind wanders.
• With どこからともなく, the source is irrelevant or unknowable, adding a touch of mystery or casualness.
• The pattern softens the image of a passive or semi-conscious state, making narratives feel more natural and less stiff.

Compared with straightforward adverbial expressions like 無意識(むいしき)に (unconsciously), ともなく / ともなしに carries a lighter, less clinical nuance. It describes a gentle, almost accidental drift rather than a psychological state.
