Interfaces

6. Interfaces tangíveis
Interfaces tangíveis
** Iroshi Ishii
** Tagible Media Group :: http://tangible.media.edu
:: confinadas em caixas (telas)
:: negação das habilidades físicas e dos sentidos periféricos
das pessoas
Interfaces gráficas
:: separam o usuário do ambiente
:: bits pintados
:: aumenta o mundo físico adicionando
informação digital à objetos e espaços
:: maneiras de tornar os bits acessíveis
por meio do ambiente e dos objetos
Interfaces tangíveis
:: tentativa de suprir a distância que
separa o cyberespaço do ambiente físico
:: extensão das
propriedades do
objeto para o domínio
digital
:: balanço entre
tangível e não
tangível

Objetos cotidianos aumentados
:: utilização de objetos cotidianos tradicionais e na manipulação das suas
características por meio da adição da informação digital

16. “transdutores”
Permite o fluxo comunicacional
entre o mundo físico e o digital;
Converte um tipo de energia em
outra: alterna entre a “energia
física” apropriada para seu
projeto e a energia elétrica
utilizada pelo
computador/microcontroladores.
