Sphere
A clear context
Sphere is ArcSphere's spatial metaphor. It carries forward the 1.0 design language by helping people recognize opened experiences in a concise overview and return to the one that matters now.
ArcSphere 2.0 brings ARC applications to your phone
ArcSphere 2.0 is ARC's mobile application surface. It gives supported ARC Blocklet experiences a coherent, app-like way to be used on a phone.
Continue what you started
Mobile work is interrupted and resumed constantly. ArcSphere keeps an opened experience and your place in it recognizable, rather than making you piece the task together from more entry points.
ArcSphere
Familiar direction
Back and hierarchy still matter, but they belong to the ARC experience in front of you. ArcSphere uses them to help a person continue a task, not to browse the whole Web.
One experience, more than one screen
AUP (Agentic UI Protocol) describes the meaning and actions of an interface first. The ARC runtime then presents the parts a device can support, so the same experience does not have to copy one fixed screen everywhere.
ArcSphere
Mobile first
ArcSphere focuses on mobile use, where touch, navigation, and limited attention are conditions of the experience from the beginning.
AUP
Presented for the device
On devices with the corresponding runtime and capabilities, one AUP experience can take different forms. The point is not identical screens, but continuing the same task in an interface that fits.
