Speech-generating devices (SGDs), also known as voice output communication aids, are electronic augmentative and alternative communication (AAC) systems used to supplement or replace speech or writing for individuals with severe speech impairments, enabling them to verbally communicate. [1] SGDs are important for people who have limited means ...
Such devices are known as speech generating devices (SGD) or voice output communication aids (VOCA). [36] A device's speech output may be digitized and/or synthesized: digitized systems play recorded words or phrases and are generally more intelligible while synthesized speech uses text-to-speech software that can be harder to understand but ...
The rate at which humans and machines interact is expected to increase substantially due to the changes in speed, computer graphics, new media, and new input/output devices. This can lead to qualitatively different interfaces, such as virtual reality or computational video. Large and thin displays. New display technologies are maturing ...
An interaction technique is a way of using a physical input/output device to perform a generic task in a human-computer dialogue. [1] A more recent variation is: An interaction technique is the fusion of input and output, consisting of all software and hardware elements, that provides a way for the user to accomplish a task. [2]
The following outline is provided as an overview of and topical guide to human–computer interaction: Human–Computer Interaction (HCI) – the intersection of computer science and behavioral sciences — this field involves the study, planning, and design of the interaction between people (users) and computers. Attention to human-machine ...
v. t. e. In computing, input/output (I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it ...
Device drivers are software specific to each input/output (I/O) device that enables the operating system to work without modification over different hardware. [103] [104] Another component of file systems is a dictionary that maps a file's name and metadata to the data block where its contents are stored. [105]
Computer hardware. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1][2]
