A head-wearable device, comprising: a center support extending in generally lateral directions in an arc along a first plane, the center support being arranged to be supported over a brow of a user in use; a first side arm extending from a first end of the center frame support; a second side arm extending from a second end of the center support, the center support and the first and second side arms being configured as a band extending between first and second ends respectively positioned on the first and second side arms, the first and second ends being remote from the center support and spaced apart from each other at a first distance, and wherein the band is resiliently deformable to selectively increase the first distance; an extension arm configured to present information to the user via a display element, the extension arm comprising a first portion extending at least partially along the first side arm on a first side of the center support and an elbow portion extending from the first portion to a display end that supports the display element in a position on a first side of the center support, the extension arm including a joint between the first portion and the elbow portion configured for movement of the display element at least in a direction having a lateral component relative to the center support, wherein deformation of the band to increase the first distance rotates the extension arm in a first direction, and wherein the joint is configured to enable movement that includes rotation of the display in a second direction that opposes the first direction, wherein the joint is configured such that the rotation of the display element in the first and second directions is in a second plane substantially parallel to the first plane, the joint comprising an internal hinge of sufficient friction to maintain an adjustable viewing position in which the elbow portion is placed relative to the first portion. a center support extending in generally lateral directions in an arc along a first plane, the center support being arranged to be supported over a brow of a user in use; a first side arm extending from a first end of the center frame support; a second side arm extending from a second end of the center support, the center support and the first and second side arms being configured as a band extending between first and second ends respectively positioned on the first and second side arms, the first and second ends being remote from the center support and spaced apart from each other at a first distance, and wherein the band is resiliently deformable to selectively increase the first distance; an extension arm configured to present information to the user via a display element, the extension arm comprising a first portion extending at least partially along the first side arm on a first side of the center support and an elbow portion extending from the first portion to a display end that supports the display element in a position on a first side of the center support, the extension arm including a joint between the first portion and the elbow portion configured for movement of the display element at least in a direction having a lateral component relative to the center support, wherein deformation of the band to increase the first distance rotates the extension arm in a first direction, and wherein the joint is configured to enable movement that includes rotation of the display in a second direction that opposes the first direction, wherein the joint is configured such that the rotation of the display element in the first and second directions is in a second plane substantially parallel to the first plane, the joint comprising an internal hinge of sufficient friction to maintain an adjustable viewing position in which the elbow portion is placed relative to the first portion.
