&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O processo de design de interação envolve quatro atividades básicas:
1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Identificar necessidades e estabelecer requisitos.2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Desenvolver designs alternativos que preencham os requisitos.3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Construir versões interativas dos designs, para que possam ser comunicados e analisados.4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Avaliar o que está sendo construído durante o projeto.
Espera-se que as atividades se complementem umas com as outras e que sejam sempre repetidas.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Avaliar o que foi construído é a principal tarefa do design de interação. A avaliação é feita envolvendo usuários em todo o processo de design. Algumas maneiras de atingir esse objetivo são: observando os usuários, conversando com eles, entrevistando-os, testando-os utilizando tarefas dês desempenho, modelando sua performance, pedindo que preencham questionários e até mesmo pedindo que se tornem co-designers.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Tão importante quanto envolver os usuários na avaliação é entender como as pessoas realizam normalmente as tarefas, entender que usuários diferentes tem necessidades diferentes e os produtos interativos precisam ser projetados de acordo com essas necessidades.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Além das quatro atividades básicas de design, existem também três características-chave:1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Os usuários devem estar envolvidos no desenvolvimento do projeto.2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A usabilidade específica e as metas decorrentes da experiência do usuário devem ser identificadas, claramente documentadas e acordadas de início do projeto.3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A interação em todas as quatro atividades é inevitável.
