Type name: haptics Subtype name: hmpg Required parameters: N/A Optional parameters: see section 6.2 of RFC-ietf-avtcore-rtp-haptics-13. Encoding considerations: binary Interoperability considerations: The HMPG format is a streamable binary haptic effect coding. It is designed to enable efficient coding of temporal and spatial haptic effects. The haptic effects may target specific parts of the human body and may be associated with a reference device description allowing haptic rendering software to adapt the effects to available hardware. Security considerations: See Section 3 of RFC 9695. Published specification: [ISO.IEC.23090-31]. Applications that use this media type: All applications that are able to create, edit, or display haptic media content. Additional information: File extension(s): Haptic file extensions used for HMPG files: .hmpg Macintosh file type code(s): (no code specified) Macintosh Universal Type Identifier code: N/A Fragment Identifier: N/A Deprecated Alias: N/A Person & email address to contact for further information: Yeshwant Muthusamy (yeshwant&yeshvik.com) and Hyunsik Yang (hyunsik.yang&interdigital.com) Change controller: ISO/IEC JTC1/SC 29/WG 7 (MPEG 3D Graphics and Haptic Coding) Informative References: [ISO.IEC.23090-31] ISO/IEC, "Information technology - Coded representation of immersive media", ISO/IEC 23090-31:2025, 2025, .
