A Proposed Low-cost Architecture for a Novel Smart Whiteboard: the “Textbook-on-the-Wall” project Jean-Paul Van Belle <jvbelle@commerce.uct.ac.za> Textbook-on-a-Wall EduBoard
Context • Developing countries: • 2 billion under-15 year olds • 100+ million classrooms • Sub-saharan Africa: • 120+ million kids at primary school age • South Africa • 7.4 million learners in primary schools • 4.0 million in secondary schools • more than 300 000 classrooms Textbook-on-a-Wall EduBoard
The Interactive Whiteboard • = laptop + projector + screen (input) • Advantages well-researched • Prohibitive cost for 3rd world environment • Computer literacy requirements Textbook-on-a-Wall EduBoard
Smart / electronic paper forsmart signs & electronic books Textbook-on-a-Wall EduBoard
Hardware: Smart paper Embedded CPU Flash RAM Solar power Minimal I/O Software: Full curriculum for grade or subject Minimal OS hypertext browser XML data storage(cHTML, XMLbasic) Utilities The EduBoard:An interactive “textbook-on-a-wall” Textbook-on-a-Wall EduBoard
The EduBoard • no power – no maintenance – low cost – customizable – intuitive interface • Supports teacher • empowers where insufficiently trained • enhances & supports where knowledgeable • Learners • motivated (more diversity) • quality assurance • Governments • QA minimal standards increased standards • Fasttrack educational policies and strategies • Open source content Textbook-on-a-Wall EduBoard
Smart / e-paper • Electro-phoretic displays use “electronic ink” (E Ink) – microscopic capsules • Bi-chromal bead technologies: Gyricon’s SmartPaper™ • bi-stable • low power • high contrast Textbook-on-a-Wall EduBoard
Screen Specs • 1.2 by 1.6 meters • 2 mm pixels => 600 x 800 resolution • low refresh rate (1 or 2 Hz) • 4 / 16 levels of grey scale • durable • embedded hardware • flexible backplane electronics(mylar & amorphous silicon) Textbook-on-a-Wall EduBoard
Other Hardware Components • embedded CPU • ARM, DragonBall™, XScale • wireless, USB & video support • Flash RAM • I/O = wireless or USB • Minimal keypad input • Power supply options Textbook-on-a-Wall EduBoard
Curriculum • Text is marked up with annotation tags headings, key concepts, hyperlinks & formatting. • Hierarchically structured content with a relative small granularity around the concept of individual pages. • Pages can be combined into, and addressed as, one single logical structure (a “presentation”). • All information can be hyper-linked • The actual physical storage structure is invisible to the user - different logical navigation options • Easily compressible by 50% or more • Additional information content can be added by the user. Textbook-on-a-Wall EduBoard
Curriculum Development • Traditional commercial educational content providers, such as textbook publishers and educational software providers, through “bulk license” or “teacher materials” leverage. • A (country-)specific EduBoard curriculum development project in sync with an envisaged roll-out plan. Funded by the government or private agency. • The educational community (teachers, other educationalists and interested stakeholders) in an “open curriculum” network organised (similar to OSS).

Other Software • Operating System • Linux Window CE Palm OS • Linux: QNX, LynxOS, … • Browser (e.g. Opera) • Must support HTML & XML & graphics • Customizable • Minimal input / navigation • Security & Authentication • Utilities Textbook-on-a-Wall EduBoard
Economics • Total cost • $150-$250 (?) for the display board (2006 cost price of $4-$6 for a hi-res A4) • $50-$100 for the electronics • $50 for the power system • $50 for the distribution (shipping, setup and teacher training) • mass production/ technology maturation: 50-75% reduction? • Possible economic models Textbook-on-a-Wall EduBoard
Project Plan • Phase 1: Proof of concept (2005/6) • Phase 2: Early Prototype (2006/7) • Phase 3: Full prototype (2007) • Phase 4: Test Roll-out (2008) • Phase 5: Full Roll-out (2009) • Maturation (2010+) Textbook-on-a-Wall EduBoard
Open Research Issues • HCI • Commercial model (& IP) • Funding • Input system • Acceptance and adoption issues (teacher & learner) • Research partners needed!jvbelle@commerce.uct.ac.za Textbook-on-a-Wall EduBoard
