The title 'Halexa', originates through combining Amazon Alexa and HAL 9000 ( 2001: A Space Odyssey ).
The experience comprises of conversations with a looming monolithic Alexa that commands the user instead of following the user's commands.
The central idea is to interchange the roles of the user and the voice assistant in virtual reality.
The concept revolved around the master-slave relationship between users and voice assistants.
Halexa, as an experience, intends to question this relationship and speculate how it might switch places in the future.
Aesthetically, the voice assistant is presented in an absurdist setting where the user looks up to the looming monolith while talking to it.
The only capability that the user holds in this space is the ability to speak.
The design comprised two important aspects : absurdity and reverence.
The experience comprised of five scenes built to grow eerier as the narrative moved forward.
The scenes were respectively representative of introduction, tranquility, skepticism, paranoia and chaos.
The visual aesthetic was designed keeping this narrative in mind.
Conversation was central to the experience. The conversation was staged between two characters : Halexa and the user.
Halexa is domineering and commanding. It designates the user a made-up name and calls the user by that name throughout the experience.
Each sentence spoken by Halexa starts with the name. Similar to how Amazon's Alexa is activated based on the trigger word.
The user holds no capability but to respond. They can't trigger conversations. They can't give instructions.
User tests were helpful in two regards.
One, to understand what were the common queries or statements that the user would say. And then, use it to refine the dialog flow on Watson.
Two, to test the coherence of conversation within the experience.
Following are 2D images from inside the experience, as it was presented at the ITP Winter Show 2017.
