  • Post category:MPAI

1. Introduction The Connected Autonomous Vehicle (CAV) specified by Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) - Technologies (CAV-TEC) V2.0 is a system that instructs a vehicle with at least three wheels to reach a Destination from a current Pose at the request of a human or a process. It does so by exploiting information captured and processed by the vehicle and communicated by other CAVs while respecting the local traffic law, Figure 1 represents an example of the type of…

Communicating avatars in worlds

  • Post author:
  • Post category:MPAI

An avatar is generally intended as a representation of a real or fictitious human in a virtual space. Research has dedicated much effort to creating and animating realistic avatars. However, the scope of use is typically assumed to be a closed environment such as a proprietary video game. Therefore, the portability of avatars has seldom been a priority. Some 30 years ago, the Humanoid Animation (H-Anim) standard was developed that defined a human skeleton composed of joints, segments, and sites…

An overview of the MPAI Metaverse Model – Technologies standard

  • Post author:
  • Post category:MPAI

The MPAI Metaverse Model - Technologies standard - in short, MMM-TEC V2.0 - is the first open metaverse standard enabling independently designed and implemented defines a metaverse instance (that MMM-TEC calls M-Instances) and clients to interoperate. These are the main MMM-TEC elements: The Architecture is based on Processes acting on Items based on the Rights they hold. Items represent any abstract and concrete objects in an M-Instance. Processes - possibly in different M-Instances - communicate using the Inter-Process Protocol (IPP).…

Component standards versus monolithic standards

  • Post author:
  • Post category:MPAI

MPAI has recently published two main new standards with a request for Community Comments. In MPAI lingo this means that the standards are mature, but MPAI asks the Community to review the drafts before publication. The two standards are Connected Autonomous Vehicle – Technologies (CAV-TEC) V1.0 and MPAI Metaverse Model – Technologies (MMM-TEC) V2.0. They are not “new” MPAI standards as they have already been published in earlier version, but the new versions represent significant improvements. You may ask “Why…

Data standards need Qualifiers

  • Post author:
  • Post category:MPAI

MPAI is about AI-enabled data coding across a very wide range of industries. Some industries are unable to negate dearly held traditions and make firm decisions, like MPEG standards did by specifying technology up to the last bit. MPAI must take this reluctance as a requirement for some of its standards. How can we then make standards that are technology agnostic? A standard should respond to a need and digging inside that need is a prerequisite for a meaningful standard.…

Is it possible to mitigate data loss effects in online gaming?

  • Post author:
  • Post category:MPAI

The 52nd MPAI General Assembly (MPAI-52) has approved Server-based Predictive Multiplayer Gaming (MPAI-SPG) - Mitigation of Data Loss effects (SPG-MDL) V1.0. It is a Technical Report that provides a methodology to predict the game state of an online gaming server when some controller data is lost. The Prediction is obtained by applying Machine Learning algorithms based on historical data of the online game. An online Multiplayer Game is based on a server. When this maintains consistency among all clients’ game…
