I am building a wearable computer,that will be optimized for use in an educational,especially high school,enviroment.It will serve to augment the student's memory,with a camera and a mike,as well as the student's knowledge,through encyclopedias an the internet.It will include a head mounted display,easy to use keyboard an possibly internet access.
MINIX 3 is a project to create a small, highly reliable and functional Unix-like operating system.
This OS is extremely small, with the part that runs in kernel mode under 6000 lines of executable code.
Project Goal:The goal here is to port Minix3 to pandaboard and developing all necessary drivers and make all the peripherals working.
Reflex is a suite of compiler and runtime support for applications to leverage the M3 (ducati) cores on OMAP4.
Low-power processors that are encompassed in an extremely asymmetric architecture promise very high energy-efficiency to frequent, simple computational tasks, most notably sensing. However, programming such an architecture is difficult, especially to numerous third-party developers.
Das U-Boot (Universal Bootloader) is an open source, primary boot loader used in embedded devices. It is available for a number of different computer architectures, including PPC, ARM, MIPS, AVR32, x86, 68k, Nios, and MicroBlaze.
The PandaBoard is a low-power, low-cost single-board computer based on the Texas Instruments OMAP4430 processor. It is a community supported development platform and is the first OMAP4 mobile software development platform.
The PandaBoard supports both DVI(Digital–Visual Interface) as well as HDMI(High-Definition Multimedia Interface).
Small board is connected to two LCD headers on the bottom of PandaBoard, and provides simple interface to LVDS LCD panels like those you can find in notebooks. Board supports EDID/I2C interface for automatic display settings setup. Also, there is support for LCD brightness, including automatic brightness control with help of ambient light sensor.
Schematic and Gerbers are available under GPL license.
Also, you can order bare PCB, fully assembled board, or bundle of board with LCD with capacitive touchscreen.
“The FAT file system is a widely used file system for mobile phones and other embedded devices for Multi-media applications such as MP3, video images and recording. This is because of FAT is Desktop PC compatible. But, the FAT file system is susceptible to power-failure causing corruption of file system Meta data and user data. In embedded environment corruption of data is undesirable. This paper implements a mechanism to log all file system operation and then committing to the FAT table and directory entries.
Our Project name is viSparsh.This word has been coined by our team. It is a conglomeration of two words namely vision (Vis) & Touch (Sparsh). We felt the name ViSparsh truly depicted the purpose of our project which was to aid the visually impaired people through the sense of Touch. We also thought this as an apt name for our team too whereby the same word would signify our team's aim of touching the lives of several people through our vision.
Gestures are a powerful means of communication among humans. In fact, gesturing is so deeply rooted in our communication that people often continue gesturing when speaking on the telephone. Hand gestures provide a separate complementary modality to speech for expressing ones idea. Information associated with hand gestures in a conversation is degree, discourse structure, spatial and temporal structure. So, a natural interaction between humans and computing devices can be achieved by using hand gestures for communication between them.
