i-Docs use interactive digital technology to document real life. Unlike traditional documentary filmmaking which only allows users to view a perception of reality from the outside, i-Docs allow users to participate and construct their own version of reality. 

i-Docs have evolved and are being used widely by all different types of authors and for different purposes. TV networks are incorporating them more to allow their audiences to be a part of their programs and feel involved. i-Docs are being produced for mainstream audiences and are no longer considered a niche form. They are being used in independent productions, in the gamine world and even in university research.

There are four main types of i-Docs; conversational, hypertext, participative, and experiential.

Conversational i-Docs use 3D technology to give users the illusion of navigating freely through a documented world, for example; gaming worlds.

Hypertext i-Docs (like K-films), use exploratory links that lead users to various clips which construct a perception of reality.

Participative i-Docs involve users in the production process. For example; they may edit the i-Docs online, shoot video to be used in the i-Doc or be a part of the distribution process.

Experiential i-Docs use mobile media and GPS to record testimonials in a particular location which can then be accessed by users who visit the same location. It brings the users into physical space and challenges their perceptions.

Audiences consider these aspects as being important to their i-Docs experience; they should appeal to their emotions, personal gain (should feel benefited from the experience), limitless self-expression, and should appeal to the greater good.

While audiences want to be active in the creation of i-Docs, a problem may arise if it inhibits the author’s artistry. While a user may want to be involved in the process at an early stage as it would benefit their experience in participation, the author will then have less control over their i-Doc which may in turn affect their experience.
