В днешно време, на повечето ученици им се налага да превключват между учебниците и дигиталните си устройства, за да извлекат възможно най-много от учебния материал. Именно в този контекст се заражда идеята за Klett AR. Породена от личния ни опит като ученици, ние осъзнахме, че стандартния подход към образованието не успява да задържи вниманието на учениците. За нас е гордост да представим нашето динамично решение, което съчетава съдържанието в учебниците със силата на модерната технология. Като сканирате страница от учебника, може да се пренесете в специално създадено за вас съдържание, изпълнено с 3D модели, анимации, видеоклипове и аудиофайлове. Това е скок от двуизмерните ограничения на страницата на учебника към богатсвото на дигиталното обучение. Така сложните идеи стават осезаеми, а абстрактните понятия - лесно усвоими. Сътрудничеството ни с Klett е доказателство за развитието в образованието, давайки му възможност да бъде по-разбираемо и интересно. Оценявайки огромния потенциал на обогатената реалност, Клет, лидер в образователния сектор, обедини усилията си с нашето отдадено трио - Огнян Траянов, Виктор Неделчев и Димитър Костадинов, в стремежа ни да иновираме образователния процес. Нашата мисия е да превърнем образованието във взаимно ангажиращ процес. Решението ни не е просто приложение, а инструмент, който подхранва връзката между преподаватели и ученици. Ние старателно подбрахме цифрови ресурси, които не просто добавят пластове интерактивност, но и внасят стремеж в учебния процес, защото твърдо вярваме, че мотивираният ученик е успешен ученик. В същността си нашето приложение е връзка между хартиения и дигиталния свят, между абстрактното и конкретното и между преподавателите и учениците. Каним ви да се присъедините към нашето пътешествие, което прави образованието не само ефективно, но и наистина вълнуващо.
