DescriptionIndigenist technology co-design and co-development (ITCD2) turns the lens on technology research, design and development. ITCD2 is an approach to decolonising existing technology design and development. This approach facilitates a process for all researchers, designers and developers to critically analyse their own methods and biases. It does so by scaffolding of the understandings of those biases derived within the contexts of social, institutional and political dimensions that impact Aboriginal and Torres Strait Islander peoples' lives in Australia. This is important because these understandings influence the way researchers and technologists think about technology design and development with, for and about Aboriginal and Torres Strait Islander peoples' country, cultures and knowledges. This approach extends existing design and development approaches and minimises the perpetuation of colonial interpretations and (re)constructions of Aboriginal and Torres Strait Islander peoples’ countries, cultures and knowledges into existing technologies.
