Alf Engen's Take Flight
{Unity, C#, Arduino}

Alf Engen Ski Museum Ski jump simulation.

Contribution highlight: all Unity code, most Arduino code.

This project won the Gold Award for Best Museum Environment from the Event Design Awards in 2014. The project was done at Unrivaled.

Users sign up on the touch screen by entering their name, selecting an outfit and skis, and choosing whether they want their picture to post to Facebook. Participants are allowed a practice jump and two judged attempts. To jump the user stands on a moving platform, then they must lean forward to go down the ramp, lean back to fly through the air, and lean forward again to land. Afterwards they see if they got a high score for the day or for all time.

I did almost all of the programming for this project and most of the Unity work. The moving platform has an Arduino with an accelerometer and gyroscope attached to analyze the platform’s angle, which is then passed to Unity. You can see a test I did with the moving platform here. A fan blows wind in the participant’s face to mimic realistic conditions, which speeds up as they go down the track. A picture can be taken of the user during their final attempt and uploaded to Facebook. We elected to have the picture uploaded to the Take Flight Facebook page and email the user a link to this post. This prevented the hassle of remembering passwords at the touch screen and long lines. The whole experience is run off of one computer with both screens running in the same app—the left side is the touch screen interface, the right side is the game.

Stein Eriksen Residences
Model App {AS3, Photoshop}

App to control the scale model of their residences in Park City.

Contribution highlight: redesigned the app, added touch controls.

Stein Eriksen Residences has built many town homes and houses in Park City. In their office they have a scale model of all of them. They came to Unrivaled to have us make a way for them to turn on and off the lights in each residence in the model.

I came to the project midway through. The interface for toggling the lights was still rough so I redesigned it. Now it’s fun to run a finger across all the apartments to toggle their lights. The app uses the tablet’s bluetooth to connect an Arduino with a bluetooth shield to control a board of relays for the lights. I updated the Arduino code to be able to turn on multiple lights at the same time. I also added in the floor plan view to be able to see the floor plan of the last selected apartment button.

S.J. "Joe" Quinney, Alf Engen Corner {Unity, C#}

A display at the Alf Engen Ski Museum.

Contribution highlight: all Unity development.

This display, made with Unrivaled, is meant to show significant moments in the lives of S.J. "Joe" Quinney and Alf Engen, as well as Ecker Hill.

Ominoes {AS3, Flash, Illustrator}

Puzzle game personal project.

Contribution highlight: The whole project. I play it for fun a lot as well.

Festival of Trees {AS3, Flash, Photoshop}

Banner app that hosts fundraisers for The Children's Miracle Network.

Contribution highlight: lead programmer, all animations, some illustrations.

A small banner app installed on websites that allowed users to donate to The Children's Miracle Network by purchasing ornaments for these digital trees. Users could also create their own tree and invite people to contribute to it.

I was the main programmer at Rain Interactive on this project and was also able to contribute to the visuals. I helped with the wireframes and the design. I illustrated and animated the characters that appear in this scene as well as the subtle animations (candle flames and shooting stars). I programmed the magic dust effect that the elf used to disappear, and that magic dust was also used when an ornament was purchased and appeared on a tree.

Floral Quarrel - Mini Park {Arduino}

A “mini park” with talking flowers. They’ll respond to your tweets as well.

Contribution highlight: most Arduino code.

We at Unrivaled built this mini park to be installed in downtown Salt Lake City, Utah. There are planters with different plant motifs from around Utah. In each planter there are plants that talk and move when someone walks by them. Throughout the garden there are labels with the park’s Twitter account and hashtags that you can use, to which the flowers will respond when you tweet.

I did most of the Arduino programming for this. There are Arduino Mega boards in each of the planters with radio components so they can communicate with each other. Each board has an audio shield with a speaker. There are servos connected to certain plants to make them move. One of the Arduinos has a cell phone shield as well that is used to receive text messages. When someone tweets at the park’s account this board receives a text message and recognizes the hash tag and plays a scenario with the different flowers in response.

Studio J {AS3, Flex}

Online scrapbooking app that uses Close To My Heart's papers and embellishments.

Contribution highlight: systems for image based fonts, coloring black and white pattern pages with custom colors, coloring black and white embellishments with custom colors.

At Rain Interactive we created Studio J, an online scrapbooking application, for the scrapbooking company Close to My Heart. It used their paper patterns, embellishments, and layouts to make good looking scrapbooking pages fast and easy. Once the page is completed the user can order prints of the pages.

I worked on many parts of the application, but one of my favorites was creating the quick title tool. With their scrapbooking kits they have alphabet stickers. For the app we wanted to be able to use these letter images as fonts, so I programmed the quick title tool along with a separate application that allowed someone at Close to My Heart to build the image fonts. This video shows off this tool.

I worked on the process of turning images of object embellishments, such as buttons or ribbons, into items that the user could place on their design and change to any color.

I also created the feature that allowed the user to select one of the pattern papers and apply a color map of any two colors onto the pattern. The colors transition from one color applied to the darks of the pattern up to the other color applied to the whites.

Playground Sessions {AS3, Flex, Adobe Air}

Application to help users learn to play piano using popular songs.

Contribution highlight: syncing the playback cursor in the sheet music to the video.

Connect a midi piano to a computer and Playground Sessions helps the user learn simplified to advanced versions of classical and modern songs. It also scores each playing attempt. It was a collaboration between Rain Interactive and Zag, the brand development unit of BBH.

Each lesson uses tutorial videos and many snippets of sheet music. While the video plays, a cursor follows along in the sheet music, showing the notes being played. Along with helping to write this application I wrote a separate application that allows someone to put together lessons, attaching together the correct video and sheet music segments. They can also create sync points that tell the sheet music cursor where and when to start and stop in order to coincide with the playing in the video. The application allows the lesson editor to add in as many sync points as needed to handle tempo variations for when David Sides, the music teacher in the videos, played the music with feeling, changing the tempo musically.

A challenge that surfaced during this process related to the cue points (time markers) feature of the Flex OSMF video player. The problem was that the dispatching of the cue points would happen within about 250 milliseconds of its noted time, about 8 video frames, which was occasionally quite noticeable. I got under the hood of the video player and rewrote most of the code that handled dispatching the cue points and achieved an accuracy of within 40 milliseconds, or 1 video frame, which fixed the problem.

Other Projects

Myriad myRisk Holographic Kiosk {Unity, Flash, VLC}

I did all the programming for the Flash and VLC version and later the Unity version. I designed much of the presentation on the touch screen, and did the animations.

This kiosk has two screens. A large portrait touch screen on the left and a holographic screen on the right. A user can interact with the touch screen to go through the presentation, and the holographic screen plays videos to go along with the presentation. The application was originally made with Flash and the VLC video player. The VLC video player can be controlled with http calls to it’s local server. We decided later to completely remake this application in Unity since the http feature of the VLC player was removed in newer versions and Unity could produce a higher frame rate for what we were doing.

Myriad myRisk Lung Cancer iPad App {Flash}

I created this app in Flash, helped create the ideas for the interactive screens and designed them, and did all the animation.

This app was used in conjunction with the Myriad myRisk Holographic Kiosk. A salesman would have this iPad app to go into more details with someone about the myRisk Lung Cancer Test.

Henry Schein Animated Gif Photo Booth {Unity}

I created the Unity tablet app to share the Gif to Giphy.com, Facebook, and email links to the user. I also designed the interfaces for the photo booth software and the tablet app.

To finish this project quickly we found software to run the photo booth and customized the interface. We then created a tablet app that was built into the sides of the photo booth to allow the users to share their photos.

Done with Unrivaled.

Buzz Wire Game {Arduino}

I did most of the Arduino programming for this game.

This was a convention booth game inspired by the board game Operation. There is a large metal rod bent to outline the company’s logo. There is a wand with a metal circle at the end that is looped around the rod. The player needs to move the wand from one side of the rod to other in the best time. Touching the rod adds penalty time. The first time this was used the player with the fastest time would get to go bowling with Steve Wozniak.
