Advances in various technologies will drive users to interact with their smartphones in more intuitive ways, said Gartner. It expect that, by 2019, 20 percent of all user interactions with the smartphone will take place via virtual personal assistants (VPAs).

“The role of interactions will intensify through the growing popularity of VPAs among smartphone users and conversations made with smart machines,” said Annette Zimmermann, Research Director of Gartner.

Gartner’s annual mobile apps survey conducted in Q4 among 3,021 consumers across three countries (US, UK and China) found that 42 percent of respondents in the US and 32 percent in the UK used VPAs on their smartphones in the last three months. More than 37 percent of respondents (average across US and UK) used a VPA at least one or more times a day.
