Si j’avais eu une calculatrice graphique aussi attrayante, peut-être aurais-je été plus attentif en cours de maths pour apprendre à tracer de belles courbes?
Ou peut-être moins, trop occupé à chercher le Solitaire, le Démineur ou Ikari Warriors au fin fond d’un sous-menu.
L’appareil ressemble plus à une sorte de téléphone pour cadres d’entreprise qu’à une calculatrice. La Prizm est dotée d’un écran LCD couleurs de 3,7 pouces. L’autonomie annoncée de la batterie est de 140 heures (elle fonctionne avec quatre piles AAA) ce qui signifie que vous pourriez la laisser allumée pendant toute une semaine de cours avant qu’elle ne tire la langue.
En ce qui concerne ses capacités, c’est une calculatrice graphique classique qui trace des cours et effectue toutes sortes de calcul que votre cerveau est bien incapable d’effectuer. Elle sortira en janvier prochain pour 130 $.

Specs :
High-resolution color LCD with full textbook-style display
The 3.7”color LCD offers full textbook-style display with the highest pixel resolution*2 (82,944 dots) and widest color reproduction*2 (65,536 colors) of any calculator. PRIZM™ comes with high-resolution fonts up to 18x24 dots (including blank dots), to enable equations and text to be displayed just like they appear in textbooks. The Blanview LCD delivers superior visibility and low power consumption, enabling color display with an estimated run time of 140 hours on four AAA-size alkaline batteries.*3
Graphical Natural Display
It doesn’t need to rely on horizontal lines and vertical lines, or dots and dashes to shade areas or link data sets. Imagine the power of using a handheld unit that illustrates a system of inequalities just like a textbook, website or software!
Picture Plot enables learning from real-life pictures
Picture Plot enables users to create their own graphs over pictures displayed on the color LCD. PRIZM™ comes with 55 types of color pictures that users can create graphs over, such as a picture of the parabola of jets from a water fountain and an image sequence of a clock’s pendulum movement. Users can perform regression calculations from the completed graphs to enhance their understanding of math functions.
Multitude of functions that leverage the color LCD
Colors can be added to a multitude of graphing objects including dotted lines, circles, and bars, as well as grid lines on graphs, labels of coordinate axes, and coordinate values displayed during tracing
Color Link Function
Links the colors used in graphs to the designated values in the spreadsheet screen, to aid the visual comprehension of trends and changes in values. PRIZM™ automatically color-codes brackets when entering equations with multiple brackets, as a visual aid to facilitate the entry of complex equations.
Next-Generation Design
PRIZM™ combines form and function – style and substance into handheld technology. PRIZM™ features an all-new case design that is the model look for the next-generation graphing calculator. It retains the key layout and style of operation that is popular among users of Casio's graphing calculators, but packages them in an attractive and sleek new body shape.
Extended Battery Life
PRIZM™ uses less energy because of the ground-breaking display technology. It will perform perfectly for 140 hours before dry-cell batteries need to be replaced. Users can also use rechargeable batteries which will last for 85 hours.
Connection Enhancements
Users can also connect PRIZM™ to Casio’s GREEN SLIM Projectors, the company’s newest data projectors, to project graphs and equations on a screen and facilitate students learning and aid teachers in the classroom. The GREEN SLIM Projector provides more than 18 school years of daily use, up to 20,000 hours, saving school budgets for equipment, not lamps.

Je ne peux pas m'empêcher d'admirer ce que l'Homme à fait!
