A concept has been formulated whereby a teacher in a classroom for students who are blind can communicate line diagrams and text directly to the students. This approach is based upon a single computer placed on the teacher's desk, with monitors on the students' desks. Access to the information displayed on the monitors is obtained by means of an optoelectronic sensor and vibrotactile output. Tw...

Abstract The present study aims to shed light on the mechanisms of ethnic discrimination in teacher assessments Hungarian primary schools. For this purpose, we use data collected among Roma minority and non-Roma majority students. First, identify a considerable difference non-blind school grades, which is beyond blind standardized test scores. Then, derive empirically predictions from different...

the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...

This article examined the feasibility of a computer-based program that alleviates the human resource challenge associated with blind photoarrays (photoarrays in which the investigator is blind to the suspect’s identity). Students watched videotaped crimes and attempted to identify the perpetrators from photoarays conducted by a “virtual officer” who responds to simple voice commands or by resea...
