Why a pin? Make it a headband or a circlet. Go all in on the scifi-fantasy aspects.
A circlet can be secure in place, has more space for power and computation, and most importantly, fashionably acceptable if done and promoted properly. Not to mention all other benefits such as turning around at the same rate as the user moving their head or easy access to the user's senses (eyes, ears) to provide feedback.
