The unified theory of acceptance and use of technology (UTAUT) is a technology acceptance model formulated by Venkatesh and others in "User acceptance of information technology: Toward a unified view" in the organisational context.
[1][2] The UTAUT aims to explain user intentions to use an information system and subsequent usage behavior.
The UTAUT model was later extended to consumer context with incorporation of three new constructs such as hedonic motivation, price value, and habit to the original UTAUT, the new extended version is popularly refereed as UTAUT2[3] [4] .
Gender, age, experience, and voluntariness of use are posited to moderate the impact of the four key constructs on usage intention and behavior.
Subsequent validation by Venkatesh et al. (2003) of UTAUT in a longitudinal study found it to account for 70% of the variance in Behavioural Intention to Use (BI) and about 50% in actual use.
