Overview

ISO/IEC 9636-5:1991 is Part 5 of the CGI (Computer Graphics Interface) functional specification. It defines the interface functions for obtaining graphical and non-graphical input from CGI Virtual Devices of class INPUT or OUTIN, and for echoing input operations on separate virtual devices. The standard describes device-independent mechanisms to control logical input devices (LIDs), collect input values, manage echo output, and query device capabilities and states.

Key topics and technical requirements

Logical Input Devices (LIDs): LIDs encapsulate a measure, state information and associated triggers. The standard formalizes initialization, allocation and deallocation of LIDs and how clients tailor their characteristics.

Input methods: Support for multiple input methods including Request, Sample, Echo Request, and Event input methods. Functions control request flow, sampling state, and echo-tracked requests.

Echoing and echo output: Functions to initialize, release and control echo entities and to perform echo output updates so values originating from one device can be shown on another.

Event handling: Event queue control (initialize, release, enable/disable events, flush, await, dequeue, transfer) enabling concurrent processing of input events while performing graphical output.

Inquiry functions and state lists: Comprehensive inquiry APIs to retrieve input capability tables, class-specific device capabilities (locator, stroke, pick, string, raster, etc.), lists of supported echo/prompt/acknowledgement types, and live device/echo states.

Data types and records: Defines the data types returned by input functions and the format of echo and device data records.

Example function families: REQUEST , SAMPLE , INITIALIZE ECHO REQUEST, ENABLE/DISABLE EVENTS, INITIALIZE ECHO OUTPUT, UPDATE ECHO OUTPUT, INQUIRE INPUT CAPABILITY, INQUIRE LOCATOR CAPABILITIES.

Applications and who uses it

Graphics system and toolkit developers implementing device-independent input layers.

Device driver and virtual device implementers who need standardized input/echo semantics.

CAD/CAM, visualization and HCI application authors requiring precise, interoperable input handling and echoing across devices.

Middleware and standards compliance engineers ensuring interoperability between graphics clients and virtual devices.

Benefits include consistent, portable input handling across diverse graphical devices, explicit event/echo control for interactive applications, and standardized inquiry interfaces for capability discovery.
