In this paper, we propose an investigation into the technology accessibility problems faced by the elderly in China. We have conducted the research by means of an exploratory survey with a Web-based questionnaire and held(More)
Sign recognition has evolved from traditional video-based to 3D-based image recognition. Most documents are presented with Kinect-based somatosensory terminals, which are limited by difficulties in precisely describing the motions performed by various palm joints. The linguistic details of sign language (SL), such as position, direction, and movement,(More)
After a systematic review on psychological and neurophysiological studies, we propose a computational cognitive model for Chinese Sign Language (CSL) perception and comprehension with detailed algorithmic descriptions based on cognitive functionalities in human language processing. A semantic neural network based on this model is introduced as the knowledge(More)
21st century is known as the “century of the brain”, neuroimaging studies about how the brain completes the various tasks are significantly increased. In this paper, we reviewed brain research about the neuroimaging of language production and language comprehension over the several decades. These studies indicate that various parts of the brain are(More)
Spoken language contrasts to the written language that provides more prosodic features. There is variety of research about pitch accent in different language. But the less attention is paid to the auditory pitch accent processing and representation of the bilinguals.

Data warehouses are used to store large quantities of materialized views to accelerate OLAP server response to query. The method to efficiently and accurately return the correct results at materialized view in a limited storage space is an important question that is being emphasized and a recognized difficulty for the ROLAP server design. This paper(More)
The natural language processing (NLP) of sign language aims to make human sign language “understandable” to computers. In achieving this goal, the text of sign language should first be segmented into sign sequences for computers to recognize. This segmentation process constitutes the basis for the information processing of sign language. With an aim to(More)
