L-Ball: Designing A Novel Sports Electronic Audio Ball for Visual Impairment Student

Background. A field study conducted by researchers found the balls used by visual impairment students at school basically used the sound by a small bell inside the ball. However, the sound emitted from the ball is very limited, the ball will sound when it is moved. This makes it difficult for students with visual impairments to find a missing ball that not emitted makes a sound. Objectives. A ...

The Effect of Using Visual Aids, Semantic Elaboration, and Visual Aids plus Semantic Elaboration on Iranian Learners' Vocabulary Learning

This study investigated the effect of using visual aids, semantic elaboration, and visual aids plus semantic elaboration on the Iranian EFL learners' vocabulary learning. To conduct the study, the researchers assigned 49 elementary learners to three homogeneous groups according to their proficiency level. Then, a pre-test of Paribakht and Wesche's Vocabulary Knowledge Scale was given to each gr...

Audio-visual Person Veriication Audio-visual Person Veriication

In this paper we investigate bene ts of classi er combination fusion for a multimodal system for personal identity veri cation The system uses frontal face images and speech We show that a sophisticated fusion strategy enables the system to outperform its facial and vocal modules when taken seperately We show that both trained linear weighted schemes and fusion by Support Vector Machine classi ...

Continuous Audio-visual Speech Recognition Continuous Audio-visual Speech Recognition

We address the problem of robust lip tracking, visual speech feature extraction, and sensor integration for audiovisual speech recognition applications. An appearance based model of the articulators, which represents linguistically important features, is learned from example images and is used to locate, track, and recover visual speech information. We tackle the problem of joint temporal model...
