A macro-mini actuation mechanism for pneumatic pouches is provided which involves stacking smaller proximal pouches (proximal layer) underneath larger distal pouches (distal layer). The proximal layer of smaller pouches is the contact area with e.g. a (human) body. Macro-mini pneumatic actuation of pouches for wearable haptic displays allows for the control of contact area of pneumatic pouches and the ability to cover large areas while maintaining a fast-dynamic response and higher spatial resolutions. This stacked pouch concept allows for pressure/force feedback to a user—something which cannot be rendered by vibrotactile actuators alone. Control of effective pouch height may also allow a potential wearable haptic display to better conform to the human body. A pressure-based display with stacked pouches could allow for larger tolerances between the display and the human body without sacrificing contact area, allowing better fit across users.

Methods and devices for encoding and decoding a data stream representative of a 3D volumetric scene comprising haptic features associated with objects of the 3D scene are disclosed. At the encoding, haptic features are associated with objects of the scene, for instance as haptic maps. Haptic components are stored in points of the 3D scene as color may be. These components are projected onto patch pictures which are packed in atlas images. At the decoding, haptic components are un-projected onto reconstructed points as color may be according to the depth component of pixels of the decoded atlases.
