Effectiveness of Cognitive Captain's Log Software on Visual-Spatial Perception of Student with Learning Disabilities
Purpose: The purpose of this study was the Effectiveness cognitive Captain's Log software on visual-spatial perception for student with learning disability. Method: This research was a pretest-posttest design with control group. The statistical population consisted of all students with learning disabilities who were referred to educational and rehabilitation centers of students with specific l...
متن کاملRetina implant adjustment with reinforcement learning
A tuning method with reinforcement learning (RL) for the Retina Encoder (RE) of a Retina Implant (RI) as a visual prosthesis for blind subjects with retinal degenerations is proposed. RE simulates retinal information processing in real time by means of spatio-temporal receptive eld (RF) lters and generates electrical signals for stimulation of several hundreds of ganglion cells (GC) to regain a...
متن کاملEvaluating the Effectiveness of Daylight Performance Metrics in Predicting Visual Comfort Case Study: Educational Architecture Design Studios in Tehran
It is essential to ensure that adequate daylight penetrates in, especially, educational environments. In spite of positive significant impacts of daylight on the emotions, concentration, and learning of students, an exceeded amount of light will lead to glare and visual dissatisfaction. Over the last few years, with the help of simulation tools and lighting indices, it is possible to predict li...
متن کاملPsychophysical test of a tunable retina encoder for retina implants
The perception-based tuning procedure of a learning retina implant as a visual prosthesis for blind subjects with retinal degeneration was tested in subjects with normal vision. A simulated retina encoder (RE) with 256 tunable spatiotemporal receptive field (RF) filters was stimulated by spatiotemporal visual patterns. RE output impulse rate was fed into an inversion module (IM) to reproduce th...
