The Device and Sensors Working Group has published a Working Draft of Orientation Sensor. This specification defines a base orientation sensor interface and concrete sensor subclasses to monitor the device’s physical orientation in relation to a stationary three dimensional Cartesian coordinate system.

The Device and Sensors Working Group has published a Group Note of Motion Sensors Explainer. This explainer is an introduction to low-level and high-level motion sensors, their relationship, inner workings and common use-cases. Common cases of event filtering and sensor fusion are introduced with examples, showing how to apply that on sensors following the Generic Sensor API specification.

The Spatial Data on the Web Working Group has published a Group Note of Spatial Data on the Web Best Practices. This document advises on best practices related to the publication of spatial data on the Web and the use of Web technologies as they may be applied to location. The best practices presented here are intended for practitioners, including Web developers and geospatial experts, and are compiled based on evidence of real-world application. These best practices suggest a significant change of emphasis from traditional Spatial Data Infrastructures by adopting an approach based on general Web standards. As location is often the common factor across multiple datasets, spatial data is an especially useful addition to the Web of data.

The Social Web Working Group invites implementation of a revised Candidate Recommendation of ActivityPub. ActivityPub allows websites a direct social connection to user software, including Follow, Like, Share, and Comment, without an intermediate social network provider. It is built on the ActivityStreams 2.0 data format, and iterates on the design of OStatus, which last month saw a wave of mainstream interest with Mastodon. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and subscribing to content.

The CSS Working Group invites implementation of the Candidate Recommendation of CSS Grid Layout Module Level 1. This CSS module defines a two-dimensional grid-based layout system, optimized for user interface design. In the grid layout model, the children of a grid container can be positioned into arbitrary slots in a predefined flexible or fixed-size layout grid. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

The Device and Sensors Working Group has published a Candidate Recommendation of HTML Media Capture. The HTML Media Capture specification defines an HTML form extension that facilitates user access to a device’s media capture mechanism, such as a camera, or microphone, from within a file upload control.
