Voice Control is designed for VR Cinema providing an extreme immersion experience for watching movies in VR.
ABOUT
Created specified command words in the Voice Search and the VR Cinema to let users operate the device without controllers intuitively, and combined with TTS to make our device more friendly to users.

Problem

User: The controller is the main way to operate VR so far, but our device’s main feature is watching movies. So we developed a new way to make users more easy to search and immerse in the experience of watching.
Business: Our company planned to give up the controllers to reduce the price of the next generation, We need to find an alternative way to control the VR device.

Understanding users

At first, our VR users have a totally different scenario with normal VR users.

Synthesis

We interviewed 10 users for the affinity diagram, and separated all the yellow notes into five blue parts which are Physical, Watching, Controllers, Searching and Environment. 
Result and opportunity:
‍The Controller problems bridge the Watching and Searching problems. Through this part, I found an opportunity to fix users problems and aligned with the business goal.

Personas

Concluded two personas to highlight the users' frustrations in process of searching and watching. These two personas guided me a lot at the next stage of design to make sure my design solves users' challenges.

Proposed Methods - Voice Control

We proposed voice control as the best way to instead of controllers. At that time this was an innovative idea in the VR platform.

Research and Assumption 

We purchased four mainstream Voice Assistants and discovered two problems.
– User has to speak out the wake up word first.
– The AI voice assistants are not smart enough to identify all the information. 

Command Words

I defined command words for Search and Viewing, and users only have to speak out these commands to execute functions.

User Flow & Interaction

A dialog box popped out in the user interface when user spoke out the command words, User continued speaking contents to search.

Watching with Voice Control 

We listed the ten most commands on the playing screen. The command would executive directly when the user speaks out the command word while watching the movie.

Result – 89% Satisfaction

The team continued to evolve and polish the Voice Control feature like added notification on the voice control guide. The usage rate of "play" and "pause" was as high as 76% and user satisfaction was 89% after the Voice Control was launched.
