Robotic Technology and Artificial Intelligence in Rehabilitation Medicine

User interface includes information input and output. There are four types of inputs currently, including Braille keyboard, QWERTY keyboard, mobile phone keypad, and voice; and two output means: Braille and voice. Voice control provides convenience, but sacrifices privacy in certain public spaces and can be less effective in a noisy environment. Many Personal Digital Assistants (PDAs) have add-on GPS software, but they are less portable. One of the benefits of PDAs is the inclusion of the Braille display, which helps blind people obtain names of the street addresses and points of interest. GPS systems on iPhone or Android cost only $5.00, whereas on other platforms, such as BrailleNote, VoiceNote, BrailleSense, VoiceSense, cost range from $1388.00 to $1977.00. Of course, the ultimate questions are what does the user need and how often do they use the device.
Applications and Performance of Current Technology
Published in John Holmes, Wendy Holmes, Speech Synthesis and Recognition, 2002
There are also commercial command-and-control applications. For example, software packages exist which enable users to customize their PCs for voice control of functions such as menu selection, Web browsing, etc. One application area where voice control is of obvious benefit is in cars, for controlling equipment such as the car radio and, in particular, for voice-controlled dialling of mobile telephones. A number can be entered by speaking the required digit sequence or by speaking some previously programmed repertory entry, such as a name or a descriptor such as “home”. Although repertory dialling requires the user first to train the system by speaking the required words, subsequent recognition performance will generally be better than can be obtained for long digit strings and the usability of the voice-dialling facility is greatly enhanced. Voice dialling is an attractive facility that is now included with many mobile telephones.
Talking to a pedagogical agent in a smart TV: modality matching effect in human-TV interaction
Published in Behaviour & Information Technology, 2021
Harnessing its network connectivity and computing power, a smart TV provides users with a variety of applications, ranging from Internet web browsing and video streaming toe-commerce. To accommodate these diverse functions, interface designers have tested novel ways to interact with their smart TV, such as selecting a menu item by gesture control (Taniberg, Botin, and Stec 2018) or operating the TV using voice commands (Han et al. 2014). Of particular interest in the current study is the voice control and an embodied agent used in a smart TV interface, for their potential to render controlling the TV a communicative behaviour. The voice control usually adopts commands that are used in a daily conversation (e.g. ‘turn on’, ‘turn volume down’, and ‘recommend me a movie’) and the virtual agent often resembles a human being, indicating that the agent is able to understand users’ commands. Thus, the voice control to an embodied agent in its interface may allow users to feel operating the smart TV as if they carry on verbal communication with the virtual agent.

Speech recognition is a technology that allows a machine to identify, understand and translate human voice signals into the corresponding text, and can be used to implement appropriate control technology (Rao and Paliwal 1986). Compared with traditional human–computer interaction, speech interaction has the advantage of convenience and can be used to implement ‘intelligent’ operations. In recent years, speech recognition technology has been applied to smart home voice control systems, car voice recognition systems and many other areas (Kumar, Suraj, et al. 2014; Pai et al. 2016). Speech interaction is more convenient and intelligent than traditional interactive approaches; however, speech interactions have rarely been applied to navigation.
