![]() The idea of 2.5D design is introduced as a way of specifically taking the structure of visual space into account, and introducing elements of 3D in a judicious way to enhance a mostly 2D information display. The picture plane dimensions of visual space are very different from the depth dimension in terms of how information is processed by the brain. ![]() In a 3D environment, our viewpoint determines how information is processed by the brain, or if it can be seen at all. Cognitive task requirements should determine which cues to incorporate in a design. We can, for example, choose to use linear perspective, or not, and we can choose to use stereoscopic viewing, or not. However, depth cues are not an all-or-nothing design choice. Incorporating depth cues can enable us to design visualizations that seem three dimensional. The different kinds of depth cues are described including linear perspective, occlusion, stereoscopic depth and motion parallax. These are the means whereby we process distances away from our view point. We begin with an introduction to depth cues. Tested with the Ardunio Uno, Mega, and Duemilanove, the Board of Education Shield facilitates circuit-building and experimentation with different varieties and combinations of electronic components and sensors.Colin Ware, in Visual Thinking for Information Design (Second Edition), 2022 Abstract The Board of Education Shield, a variation of our cornerstone BASIC Stamp BOE and multi-core Propeller Activity Board, is used by students and hobbyists in many countries. Parallax offers a development board and robotics kit specifically for the Arduino, as well as example code for many of our most popular sensors and accessories. The BASIC Stamp microcontroller is ideal for hobby, lower-volume engineering projects and education due to ease of use and a wide support base of application resources.Direct video output and easy interface to external periferals such as a keyboard, mouse, and VGA monitor.The PBASIC language of the Stamps place many powerful commands in the hands of users, making complex tasks such as pulse width modulation, serial communication and button debounce as simple as a single instruction.All general purpose I/O lines on Stamp modules can be set as either inputs or outputs, and can be switched at run time. The efficient BASIC Stamp 2 draws a mere 3 mA of current while running, and in sleep mode requires only 50 μA.The BASIC Stamp family of microcontrollers can execute between 2,000 and 19,000 instructions per second, depending on model.The enormous amount of information for BASIC Stamps available in print and online make the Stamp line one of the most widely documented μ-controllers in existence.ĭue to its ease of use, Stamp ICs are the microcontrollers of choice in thousands of high schools and universities around the world. Functioning as stand-alone ICs, beginners can plug a BASIC Stamp into a board and immediately begin programming, with no other circuitry required. The BASIC Stamp line of microcontrollers was created specifically to make learning to use a μ-controller simple and easy.Ī BASIC Stamp is a single-board computer that runs the Parallax PBASIC language interpreter in its microcontroller. Shop BASIC Stamp Education Software Q & A Get Started OEM Parts Programmed in C/C++ with Propeller GCC, Object-based Spin language, Low-level Assembly which can execute at up to 160 MIPS (20 MIPS per cog).Eight concurrent, independent processors on a single chip.The ability to develop objects (object orientated programming) makes complex project development easy.Pre-written objects for the Propeller are offered for free on the Parallax website, including drivers for mice, keyboards, video, VGA, and many more.Users appreciate the overall processing power, I/O capabilities, on-board video generation, parallel processing, easy connections to popular PC peripherals and more. A shared system clock keeps each cog on the same time reference, allowing for true deterministic timing and synchronization. ![]() Developer has full control over how and when each cog is employed there is no compiler-driven or operating system-driven splitting of tasks among multiple cogs. This chip features eight 32-bit processors and a shared memory and system clock, making true independent and cooperative simultaneous multi-tasking possible. ![]() Shop Propeller Education Q & A Share Objects Software Application Notes Datasheet Hobbyists and Engineers alike are finding new uses for the Propeller chip every day. It is used in many industries including manufacturing, process control, robotics, automotive and communications. The multicore Propeller Chip, our newest chip, is gaining tremendous popularity. The BASIC Stamp, developed in 1992 is widely used by hobbyists, engineers, and students around the world. Parallax designs and manufactures two microcontrollers, the BASIC Stamp and Propeller chip.
