Gather Participants for High-Fidelity Prototype Testing

Participation Proclamation! (Part 2)
Group Members Responsible: Alyssa, Connie, Ted

“We… w-we can’t give up,” stuttered Ted, who was on the verge of passing out after days of coding nonstop in order to meet the team’s milestone deadline. It wasn’t just Ted — the entire team had been writing up the tutorial code that Ngoc and Ashish had valiantly compiled so that they can learn the basics of Three.js and the Leap Motion API.

Connie was curled up into a ball in the corner of the iSchool T.E. Lab of Mary Gates Hall. Alyssa was shaking, perhaps from the unfathomable amount of coffee that she had consumed over the last 24 hours in order to maintain her zombified state-of-mind. You could see her bloodshot eyes from a mile away. But Alyssa carried on, out of sheer willpower and motivation.

“Hang in there guys! We’re almost done,” encouraged Alyssa, who was the only, and not to mention most optimistic, project manager the Ghost’s Anatomy team could ever ask for. “I know you guys are all tired from coding all night long, but once we put together our lo-fi study results, we only have one thing left to do!”

“Wuh… one thing left to do?” reiterated Ted.

“Yeah… one thing left…” affirmed Alyssa. And then thump.¬†Alyssa was down. Ted hesitated. He was lost, confused, and broke down, shaking his head in denial while scratching his scalp in utter defeat.¬†And then there was silence.

Time stopped for a brief moment. Not a single creature in the room moved a muscle. The room gave off an atmosphere of despair. It was as if your roommates were stealing all of the internet bandwidth while you sat in your room, alone, waiting for the next episode of House of Cards, on Netflix, to buffer. Sheer and utter torture.

And then it hit them. Connie, crawling towards the team similarly to how the boy from the Grudge did, gathered all of the remnants her energy and used the last of it up to give the team one final push.¬†‚ÄĚWe only have one thing left to do!‚ÄĚ she rejoiced. ‚ÄúWe need to gather participants for our hi-fidelity prototype testing!‚ÄĚ

And so our quest continued. We gathered a list of possible participants, and made sure that our pool of participants was as diverse as possible, ranging from undergraduates to instructors to medical students; from nyancats to octopi to doges.

I hope you enjoyed reading both chapters of the Participation Proclamation Saga.
Until we meet again!

Design API Specification and New Directions

Linking the Leap Motion API and three.js library requires a lot of integration and complicated development. To abstract the functions we need for our application, we were initially planning to write an API that abstracts the backend linkage between the two resources, and allow us to make simple function calls in order to develop certain features.

Today, we met with an amazing researcher and developer named Trond Nilsen who is working on a related anatomy application for his dissertation. He is using 3D models in conjunction with the three.js library, which is exactly what we need to do for our project, and his project contains a great deal of the core functionality we would need for our application. To our delight, Trond has vocalized his desire to collaborate with The Ghost Anatomy Project in order to gain a more user-centric and displayable interface. We are incredibly exited to collaborate with such an experienced developer with extensive knowledge in both the field of anatomy and development of anatomy-related applications.
 
While we were originally going to build an API to mask the backend code in combining the Leap Motion and three.js code, Trond has agreed to complete most of the three.js code, leaving it up to our team to use the Leap Motion API and integrate it. Since we are no longer dealing with three.js ourselves, it is no longer necessary for us to write an API or have a Design API Specification detailing the features of the API. In response to our shifting development direction, we have created a document expressing the details of our collaborative development with Trond.

Gather Participants for Low-Fidelity Prototype Testing

Participation Proclamation! (Part 1)

“What a sexy idea! Our Low-Fidelity Prototype will blow everyone’s minds!” exclaimed Ted, who was mesmerized by Alyssa’s creative design concept. The research team had gathered around the lone rectangular table in the iSchool T.E. Lab of Mary Gates Hall for their weekly researcher meeting. They had but one goal: to figure how they should conduct the lo-fi prototype testing for their Ghost’s Anatomy project.

After a brief moment of relief, laughter, and joy, Alyssa brought up one of the most thought-provoking questions that had ever been brought up during our meetings.

“But now what are we supposed to do?”

And then there was a slight pause. What lasted for seconds seemed like it lasted for minutes; hours; no, days. All three researchers looked into the yonder whilst trying to figure out what the team’s next course of actions should be. Not only could they hear the cooling fans roaring throughout the room, but they could feel every bit of wind tingling through their bodies, almost as if they were holograms themselves.

And then it hit them. Connie stood up.¬†“I know! I have it!” she rejoiced. “We need to gather participants for our low-fidelity prototype testing!”

And so our quest began. We gathered a list of possible participants, and made sure that our pool of participants was as diverse as possible, ranging from undergraduates to instructors to medical students; from nyancats to octopi to doges.

WARNING: Spoiler alert! (highlight below to view content)
In the end, our quest was a success! We were able to gather not one, not two, but five spectacular participants. Our participant demographics ranged from students to instructors to even Teds!

Stay tuned for another exciting episode of Participation Proclamation.
In and out!

Low-Fidelity User Testing

After the lo-fi user testings, we concluded the most commonly adapted gestures and the additional functions that were suggested by our interviewees.

For zooming in/out, most people suggested pinching with two fingers, or grabbing and releasing. For rotating, grabbing the model and turn the hand, sideways swipe with vertical palm, or one finger sideways swipe are the common gestures the interviewees did. For taking off layers, grabbing a layer and groping motion away is the most common gesture among the interviewees. For isolating a body part, some people suggested to use a grabbing motion to select a body part and after the selected body part is highlighted, use a groping motion to take of the layer. Some also suggested to use a menu or a cursor to select a body part, and swipe to the left to peel it off. For navigating to the quiz, most people suggested to go through menu and choose a specific category. Some people prefer to swipe up the menu from the bottom; some people suggested to swipe left from right top corner. And most of them would like to be able to access to the menu anytime to switch a category. For the quiz contents, open-end question, multiple choice, and truth-or-false are all popular among the interviewees. Most of the interviewees expected various question type instead of simply asking the names of body parts. Furthermore, questions such as tracing the pathway of a hormone, where it’s produced, where it’s secreted, and what it influences, etc. are more advanced questions.

Additionally, some interviewees suggested us some functions that they would like to use on our application. Couple of the interviewees suggested that it would be helpful to show names of body parts when they point at them on the application. In addition, they would also want to be able high light the body parts during a group study. Some people also suggested that they would like to be able to search for a specific part of body through a search bar and  with maybe physical keyboard. Lastly, a tool bar is also requested by many interviewees. Users would like to be able to easily switch between different functions such as show-name function, or zoom in/out function.

After gathering all the most intuitive functions and gestures, we will be able to design our hi-fi prototype, which will be closer to our real application.
