Monkeying Around with Autism Assessments: Kinect-based game by Vectorform and Kaiser Permanente therapists offers a barrel of possibilities!

"The goal was to build a game that is extremely accessible, non-complex and includes simple mechanics that children with autism can quickly understand to retain their attention, prevent over-stimulation, encourage play, and prevent frustration." -Vectorform "Monkey Business" Team


I recently had the chance to visit the team at Vectorform's Royal Oak (MI) headquarters and experience a demo of one of their newest applications, a Kinect-based game developed to assist in the assessment of children with autism. The game, known as Monkey Business, was designed in collaboration with physical, occupational, and speech therapists from Kaiser Permanente, a large health care service provider in California. The project was supported by Kaiser Permanente's Innovation Fund for Technology group.

I was impressed!

As I watched the demo, it was clear that much time and attention was given to the input of the therapists at Kaiser Permanente. The avatar in the game is a friendly monkey who embodies the mannerisms of a friendly, curious child.  The artwork is visually appealing and not too busy. The sound effects relate to the interaction at hand and provide feedback to the child as they engage in various game-like tasks designed to assess visual-motor, gross motor, and basic receptive language skills.  Another good feature of this application is the simplicity of the screens designed for input of the child's information and viewing data regarding progress.

In my opinion, the Monkey Business assessment game has the potential for use in school settings, and would be enhanced if additional assessment activities are provided in the application.  Expanded activities within the Monkey Business environment could support a range of treatment, education, and related intervention efforts. In addition to supporting assessment and intervention of children with autism, the Monkey Business concept would be especially useful in working with children who have experienced a traumatic brain injury.


Below are screen shots and descriptions of a few activities from the Monkey Business game:

Lily Pad Jumping Test
In the jumping test, the child is asked to jump across a pond, from one lily pad to another.  The child is provided with a set of toy lily pads on the floor.  As the child jumps, the Kinect sensor picks up movement and displays the jumps on the screen in the form of the monkey.























Balance Beam Test
The following screen shot depicts the monkey avatar crossing a stream on a balance beam. The monkey's movements reflect the child's movements across a real balance beam in front of the Kinect sensor and a large screen display.






















Block Building Test
In the block building test, the monkey avatar encourages the child to build a tower of blocks to match the one displayed on the large screen.  The child uses real blocks, placed on a table, to build a tower while the monkey provides encouragements.  Objects other than blocks can be used, as the Kinect sensor is capable of identifying a variety of objects that can be use for building and stacking.






















Clinician Screens
The screens designed for inputting and reviewing data regarding the child are designed with simplicity and ease-of use in mind, as shown in the pictures below:












































In the present version of Monkey Business, a TV remote is used to control the application. It is possible that future versions of Monkey Business could integrated with a Smartwatch to input student information and control the activities in the application.  


Comment: As a school psychologist who works with children, teens, and young adults with autism and other significant disabilities, I know how difficult it can be to conduct assessments using traditional test materials.  If a student has difficulty interacting with unfamiliar adults, has communication challenges, or has motor difficulties, it may not be possible to administer an assessment that generates meaningful or valid results.  Even if the student is capable of completing some of the traditional test tasks, much time and effort is required on the part of the evaluator to sustain their interest, effort, and attention.   

To get a better picture of a student's emerging skills, I use interactive multimedia applications during my assessments of children with autism.  Newer technologies such as interactive whiteboards, larger touch-screen monitors, and tablets have proven to be useful tools in assessment.   A significant drawback to my approach is that it is cobbled together and might be difficult to replicate by other evaluation teams.  I see a growing need for a range of technologically-enhanced tools for assessment, including applications that offer opportunities for playful engagement.  Monkey Business holds potential to fill the bill.

What next?

I'd like to share some stories about the people who make things come to life at Vectorform. During my visit, I learned that they are involved in a number of projects related to health care and are always brainstorming new ways to harness technology for their various clients.  

Over the past several years, I've followed Vectorform's journey as they've jumped off of the desktop and transformed from web-developers to Post-WIMP explorers of natural user interfaces and interaction.  The most recent area of exploration is Google Glass. 

Intrigued by Google Glass?  So am I.  

During my visit to Vectorform, I had a chance to see the world - or rather Vectorform's basement conference room - through Google Glass.  As soon as I put them on I was flooded with ideas, and will expand on my ideas, and those of others, in future posts.

In the meantime, take the time to read an excellent post by Kevin Foreman, Vectorform's Director of Product Vision.  In "The Glass Experience", Kevin provides an in-depth reflection of his experience wearing Google Glass throughout his daily routine.  He also explains the inner workings of the hardware, the strengths and limitations of the Glass system, details about the user interface, the "on-board" accessories, and a few comments about what it is like to be a new Glass-wearing celebrity.

Leap Motion and Google Earth Experiment: Cute Doggie Photo-globe Mashup

Leap Motion and Google Earth Experiment: Cute Doggie Photo-globe Mashup 

I finally experimented with my Leap Motion controller and Google Earth, using a mashup I created a few years ago with pictures of cute dogs from my Flickr photo-stream.  In the video below, you can see that my gesture navigation skills still need some practice!

I should have watched the following video of Leap Motion in action with Google Earth before trying this experiment at home : )  

I am pretty sure that developers will be able to tweak Leap Motion + Google Earth interaction in the near future.  I'd like to adapt it for use with kids as well as adults who have mild motor impairments.





















Cute Doggies Photo-Globe Mash-up using Google Earth and a Flickr Set (How-to)

If you'd like to make your very own photo-globe using Google Earth and Flickr photos, here are the directions, ported and updated from a previous post:


This photo is a screen shot of photos of just about every dog I know, and some that happened to cross my path. In this post, I'll share some information about how to create a photo-globe in Google Earth. 

The first step is to make sure you have lots of pictures related to your theme uploaded to a site such as Flickr.  (You can also create a photo-globe using pictures from your computer's hard drive.)

To get the pictures into Google Earth, I used the Image Overlay feature, and in the "link" textbox, I entered the image URL for each picture that I'd previously loaded as a set in Flickr.



To do prepare for this, make sure you go to "view" tab on the upper left-hand section of your screen, and make sure that "toolbar" is checked. Also make sure that "Grid" is selection, as this will help make it easier to arrange and align your pictures.  You can turn off this feature later. Near the top of the screen, click on the Image Overlay icon. (I've highlighted it in the picture.)



You'll have to enter the URL of the image you'd like to add to the globe in the "Link" textbox, which I've highlighted in the above picture.  In this case, I've used a link to one of my pictures in a Flickr set I created for this project.

One thing to keep in mind is that the picture will take up a much larger space than you might prefer, so you'll have to adjust the size using the green markers:

Positioning the Overlay in the Viewer
The following directions are from the "Positioning the Imagery in the Viewer" section in the help section:


  1. Use the center cross-hair marker to slide the entire overlay on the globe and position it from the center. (Tip: do this first.)
  2. Use the triangle marker to rotate the image for better placement.
  3. Use any of the corner cross-hair markers to stretch or skew the selected corner. If you press the Shift key when selecting this marker, the image is scaled from the center.
  4. Use any of the four side anchors to stretch the image in or out of from the selected side. If you press the Shift key when doing this, the image is scaled from the center.

TIP:  Try positioning the center of the image as a reference point first, and then use the Shift key in combination with one of the anchors to scale the image for best positioning.

Directions updated to reflect latest version of Flickr, as of 5/27/13:

To find the image URL for a photo in Flickr that you wish to link on your photo-globe, select your desired photo and right click "Copy Image URL".
















Put your curser in the Link section of  the "New Image Overlay" dialog box in Google Earth, and right click to select "paste" from the drop-down menu















Then repeat the process.  It helps to name each picture so that you can find it easily in Google Earth.

To enhance your mash-up, you can add place-marks that contain URLs that link to additional information about the subject of a picture, such as blog posts with embedded videos and/or text related to a picture, and so forth. Directions can be found in Google Earth's help section.

The process of building a photo-globe in Google Earth is a bit tedious.  If someone has a short-cut to share, please let me know!

Leap Motion: Low Cost Gesture Control for Your Computer Display

Jessica Vascellaro, of the Wall Street Journal, reports about gesture,  motion. and even object control for computers, highlighting the work of  Leap Motion and Flutter.




Apparently the Leap Motion sensor is less expensive than Microsoft's Kinect. It can track movements down to 1/100 of a millimeter and can track fingers and movement. It handles interaction with 8 cubic feet of space.


Below is a video from the Leap Motion website:

Kinect in Education! (kinectEDucation)

Although I'm currently exploring the world of interactive HTML5, interactive video, etc., I think I just might make "kinecteducation" the focus of my tech-hobbies. I have some experience with game programming-one of my computer courses required a project using XNA- and I know quite a bit about gesture and multitouch, multi-user interactio, so it would'nt be too much of a stretch.


My motivation?

As a school psychologist, my main assignment is a school/program for students with disabilities, including about 40 or so who have autism spectrum disorders. Yesterday, the principal of the school attended a demonstration of the Kinect and requested that our school be considered for piloting it. One of my other assignments is a magnet high school for technology and the arts, and rumor has it that it will be offering a game programming curriculum.  I'd love to co-sponsor an after-school game club and encourage the students to program educational apps for the Kinect sometime in the near future! 


I'm also working as a client, in collaboration with come of my educator colleagues, with a team of university students who are creating a communication/social skills game suite geared for students with autism and related disabilities....


I'm inspired by the possibilities!


We have large SMARTboards in each classroom and in other locations around the building, and we have a Wii set up in the large therapy room adjacent to my office. The Wii has proven to be very useful in helping the students develop social and leisure skills that they can use in and outside of the school settings, but some of the students have difficulty manipulating the buttons on the controllers.


You can get Kinect-based apps from the Kinect Education website! Below are selected links from the website:

You can also get additional information from the Microsoft in Education "Kinect in the Classroom" website.

Below are a few videos to give you an overview of how open-source applications designed for the Kinect can be used in education:
