  • Lightweight Smart Glass System with Audio Aid for Visually Impaired People
    Lightweight Smart Glass System with Audio Aid for Visually Impaired People Feng Lan, Guangtao Zhai and Wei Lin Institute of Image Communication and Information Processing, Shanghai Jiao Tong University, Shanghai, China Email: fdeanlan, zhaiguangtao,linwei181491g @sjtu.edu.cn Abstract—In this paper, we present a new smart glass system for people who are blind or have low vision. Individuals with visual disability are difficult to communicate effectively with their environment. The blind or visually impaired rely largely on their other senses such as hearing, touch, and smell in order to understand their surroundings. It is pretty hard for them to go out alone, not to mention finding toilets, subway stations, restaurants and so on. Giving blind people the great accessibility to their environment is the objective of the smart glass system. This smart glass system can see the world for them and give voice instructions and hints through wireless bone conduction headphones. This smart glass system will help visually impaired people gain increased independence and freedom in city life. And Fig. 1: Snapshot of the prototype smart glass. we have implemented an application of public signs recognition on the smart glass system. This application can detect and recognize the public signs in cities, and give corresponding voice hints to the blindness. The proposed prototype system is based on Intel by Intel as a development system for wearable devices. Its Edison, and the application in the system is written in C++ with dimensions are 35:5 × 25 × 3:9mm, with components on both libraries of OpenCV. Extended demonstration of the system will sides.

  • Ilore: Discovering a Lineage of Microprocessors
    iLORE: Discovering a Lineage of Microprocessors Samuel Lewis Furman Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Computer Science & Applications Kirk Cameron, Chair Godmar Back Margaret Ellis May 24, 2021 Blacksburg, Virginia Keywords: Computer history, systems, computer architecture, microprocessors Copyright 2021, Samuel Lewis Furman iLORE: Discovering a Lineage of Microprocessors Samuel Lewis Furman (ABSTRACT) Researchers, benchmarking organizations, and hardware manufacturers maintain repositories of computer component and performance information. However, this data is split across many isolated sources and is stored in a form that is not conducive to analysis. A centralized repository of said data would arm stakeholders across industry and academia with a tool to more quantitatively understand the history of computing. We propose iLORE, a data model designed to represent intricate relationships between computer system benchmarks and computer components. We detail the methods we used to implement and populate the iLORE data model using data harvested from publicly available sources. Finally, we demonstrate the validity and utility of our iLORE implementation through an analysis of the characteristics and lineage of commercial microprocessors. We encourage the research community to interact with our data and visualizations at csgenome.org. iLORE: Discovering a Lineage of Microprocessors Samuel Lewis Furman (GENERAL AUDIENCE ABSTRACT) Researchers, benchmarking organizations, and hardware manufacturers maintain repositories of computer component and performance information.
