  • Raspberry Pi turns retro radio into interactive storyteller

    Raspberry Pi turns retro radio into interactive storyteller

    Reading Time: 3 minutes

    8 Bits and a Byte created this voice-controllable, interactive, storytelling device, hidden inside a 1960s radio for extra aesthetic wonderfulness.

    A Raspberry Pi 3B works with an AIY HAT, a microphone, and the device’s original speaker to run chatbot and speech-to-text artificial intelligence.

    This creature is a Bajazzo TS made by Telefunken some time during the 1960s in West Germany, and this detail inspired the espionage-themed story that 8 Bits and a Byte retrofitted it to tell. Users are intelligence agents whose task is to find the evil Dr Donogood.

    The device works like one of those ‘choose your own adventure’ books, asking you a series of questions and offering you several options. The story unfolds according to the options you choose, and leads you to a choice of endings.

    What’s the story?

    8 Bits and a Byte designed a decision tree to provide a tight story frame, so users can’t go off on question-asking tangents.

    When you see the ‘choose your own adventure’ frame set out like this, you can see how easy it is to create something that feels interactive, but really only needs to understand the difference between a few phrases: ‘laser pointer’; ‘lockpick’; ‘drink’; take bribe’, and ‘refuse bribe’.

    How does it interact with the user?

    Google Dialogflow is a free natural language understanding platform that makes it easy to design a conversational user interface, which is long-speak for ‘chatbot’.

    There are a few steps between the user talking to the radio, and the radio figuring out how to respond. The speech-to-text and chatbot software need to work in tandem. For this project, the data flow runs like so:

    1: The microphone detects that someone is speaking and records the audio.

    2-3: Google AI (the Speech-To-Text box) processes the audio and extracts the words the user spoke as text.

    4-5: The chatbot (Google Dialogflow) receives this text and matches it with the correct response, which is sent back to the Raspberry Pi.

    6-7: Some more artificial intelligence uses this text to generate artificial speech.

    8: This audio is played to the user via the speaker.

  • Finding your way in the enchanting Arca’s Path

    Finding your way in the enchanting Arca’s Path

    Reading Time: 4 minutes

    VR is a powerful step forward for technology to allow for immersive new experiences in bold new virtual worlds, reaching new audiences and breaking down barriers for interactivity. The team at Dream Reality Interactive believes that there are further opportunities to create engaging, artful experiences that can connect with players in increasingly intuitive and approachable ways. We sat down to speak with them on how this philosophy shaped the atmospheric hands-free VR title Arca’s Path – out now on Viveport.

    Interview by Nathan Ortega, Viveport

    [youtube https://www.youtube.com/watch?v=j1eb9crf7-4?feature=oembed&wmode=opaque&w=730&h=411]

    Tell us a bit about yourself and the team at Rebellion

    Delainey: My name is Delainey Ackerman and I worked as a Technical Artist at DRI on Arca’s Path VR. Essentially that means bridging the gap between artist’s creativity and programmer’s problem solving to bring a cohesive and visually stunning experience to players.

    Chris: I’m Chris Murray, the sound designer on Arca’s Path VR. I was responsible for creating all the sound effects and implementing Raffertie’s score into the game.

    Talk a bit about your previous experience developing content for VR and how it informed your vision for Arca’s Path

    Delainey: Previously I was the Technical Artist for Hold the World – a Factory 42 production for Sky – a VR experience with David Attenborough set in London’s Natural History Museum. As a photorealistic experience, Hold the World provided integral experience in lighting, graphics, and designing VR spaces that fully immerse a player within a generated experience.

    Chris: I also worked on Hold The World – a Factory 42 production for Sky – as Quality Assurance Lead and Technical Sound Designer, testing the entire experience as well as implementing many of the sfx.

    What were some of the biggest inspirations to the creative direction of Arca’s Path?

    Delainey: Arca’s Path was influenced by science fiction and classical fairy-tale narratives including Wizard of Oz and Hansel and Gretel. The art direction was heavily inspired by the vaporwave movement, incorporating bold colour palettes with glitching of VHS degradation. These inspirations helped us to create two worlds; a lowlife, high tech scrapheap where the protagonist finds a futuristic headset and the wondrous, lush simulation to which she is transported.

    What are the greater themes of Arca’s Path and how do these themes factor into the gameplay?

    Delainey: Arca’s Path revolves around the contrast of reality and simulation, becoming infatuated with utopia and trapped within its inviting clutches.

    Arca’s Path is a hands-free experience, allowing players to explore dreamlike environments and interact with things merely by looking.

    Was this mode of play – and accessibility in general – always the focus or did this approach evolve over the course of development?

    Delainey: The original brief was to design a game that could run on any VR headset. Platforms vary widely in technical capabilities and performance (controller buttons, motion tracking, CPU/GPU power etc.) yet the common thread across all VR headsets is the ability to look anywhere in 3 dimensional space. This inspired the core mechanic of moving through a world through a player’s gaze.

    This pillar wove in nicely with the narrative of Arca’s Path VR where the protagonist girl enters a simulation and the player feels as though they’re guiding her through the enchanting environments with nothing but the power of their mind.

    Were there any concepts, sequences or ideas that you wanted to work into Arca’s Path but just couldn’t find a way to make it fit?

    Delainey: With any creative project you start with myriad ideas and possibilities. As the realities of production become apparent this focuses the creative process into bringing the best of these ideas to fruition.

    What have been some of the biggest challenges in developing Arca’s Path?

    Delainey: To convey narrative without any written or spoken dialogue we relied heavily on the amazing soundtrack from Raffertie. Throughout the game the music guides the player through a journey of technical challenges and emotions.

    Chris: The sound effects were created with the aim of emphasising the language of the score at every turn while also referencing the girl’s real world outside the simulation, much like nearby sounds enter our dreams while we sleep.

    How many people were on the team throughout the development process? How long did it take to make?

    Delainey: The development team averaged 8-10 people working over 10 months. The dev team at DRI was also supported by Rebellion helping to achieve quality and maintain performance across multiple VR platforms.

    What do you ultimately want players to take away from their time with Arca’s Path?

    Delainey: Arca’s Path offers an escape from reality, both for the player and the protagonist. Hopefully the audio and visuals of the girl’s scrapheap and simulated world provide the player with the same emotional journey the protagonist experiences as she fights first to escape her bleak reality and then to regain her freedom.

    From the early reviews and video coverage from video content makers, I think it’s safe to say you nailed it! Thank you for taking the time to chat with us.

    The Poplawski’s Holiday Frights

    Reading Time: 2 minutes

    After becoming internet-famous for their interactive Christmas lights, the Poplawskis have expanded their festive offerings this year with Holiday Frights, a fiendish collection of spooky decor controlled by a Raspberry Pi.

    The Poplawskis’ holiday lights

    Full of lights and inflatable decorations sprawling across the front lawn, the annual pi-powered Poplawski Christmas setup is something we await eagerly here at Pi Towers. What better way to celebrate the start of the holiday season than by inflating reindeer and flashing fairy lights on another continent?

    So this year, when an email appeared in our inbox to announce the Holiday Frights Halloween edition, we were over the moon!

    Take control

    It’s about 5am in Easton, Pennsylvania, but I’m 99% sure the residents of the Poplawski’s Holiday Frights home were fully aware of me endlessly toggling their Halloween decorations  — on, off, on, off — in the process of creating the GIF above.

    The decorations of the Poplawski’s Holiday Frights are controlled by a Raspberry Pi which, in turn, takes input from a website. And while we’ve seen many Pi projects with online interfaces controlling real-life devices, we can’t help but have a soft spot for this particular one because of its pretty, flashy lights.

    To try out the decorations yourself, go to the Poplawski’s Holiday Frights website. Also make sure to bookmark the site, or follow the Facebook page, for updates on their Christmas edition.

    When you’re on the site, you will also see how many other people are currently online. If you’re not alone, the battle over which lights are turned on or off can commence! In case you’re feeling extra generous, you can donate 10¢ to fix the decorations in a state of your choosing for 60 seconds, while also helping the Poplawskis power their lights.
