After much research and looking at the possible options for ultrasonic sensors and their placements on IZZY. There are a couple different options that are very close in size, angle width, range, communication and voltage. They both will do what we need in detecting possible obstacles on stage. The best design I could come up with requires 8 units to be purchased. Parallax Ping's price per unit is $29.95, the price per unit for the TomTop is $8.15. The Parallax Ping))) sensor has a 20 degree view and the TomTop has a less than 30 degree view, by placing 2 of them in the front and 2 of them in the rear placed 1.25 feet in from the outside edge of the platform. Placing another one in front of each wheel that is positioned at a downward angle. The placement of the sensors was a process of figuring out the where the best place to put them gaining the most amount of coverage from each sensor. The range of these 2 sensors is from 1" to 12', the prime operating distance is around 7'. Parallax unit is 1" to 10' and the TomTop's range is 2 cm to 4 meters. Both of the sensors operate on 5 VDC; the Parallax is 35 mA, while the TomTop is at less than 15 mA. These units both use Analog signal. The 2 sensors accuracy is around 1.5". With these findings, the choice comes down to price and reliability of the units.
This site is not being kept up. Several of the add-ons are no longer available in this instance of Confluence and the macros for them need to be removed on the pages.
Welcome to my first blog post. Boy do I look like a fool posting this.
A blog is a personal journal published on the World Wide Web consisting of entries ("posts") typically displayed in reverse chronological order so the most recent post appears first. Blogs are usually the work of a single individual or a small group, and often are themed on a single subject. Blog can also be used as a verb, meaning to maintain or add content to a blog.
This is great that I can add a blog to this space. What do others think of this feature?
According to the The Digital Storytelling Association, “Digital Storytelling is the modern expression of the ancient art of storytelling. Throughout history, storytelling has been used to share knowledge, wisdom, and values. Stories have taken many different forms. Stories have been adapted to each successive medium that has emerged, from the circle of the campfire to the silver screen, and now the computer screen.”
Storytelling and learning go hand-in-hand because the process of creating a story requires the student to reflect upon and understand their topic, and then convey the information back to others; this in-turn can strengthen learning. Also since each story provides a record of the students’ thinking on the subject matter, an instructor can use the story in the assessment of student progress toward course learning goals.
There are many tools that can be used to create a digital story. Story creation can be achieved utilizing tools as simple as Microsoft Word or a blog, to the more complex tools like Adobe Premiere for digital video or Flash for interactive animations. Most of these digital tools make it easier to critique and edit stories, even for authors who aren’t very tech savvy. Each author can construct multi-leveled stories that are conveyed through a combination of hyperlinks, words, images, and sounds. Utilizing a digital storytelling assignments in the class can increases engagement and still be as involved as any other more traditional assignment.
TeachLive and The Suicide Risk Assessment Game are two examples of projects developed here at Purdue that utilize a high level of digital storytelling. Both of these projects were developed in conjunction with faculty and use storytelling to guide the students through the game requiring the utilization of critical thinking and problem solving skills.

It’s a sunny day. You’re minding your own business, trying to play a little catch-up. You’ve created a page in a Confluence wiki space which contains a table. You need to send this table to someone who doesn’t have access to the space. Cutting and pasting doesn’t maintain the structure of the table, so you get the bright idea of exporting this page to a PDF, sending that in your email.
Well it works; sort of. The PDF contains the title of this Confluence page, and you’d rather not have a title. So you get the bright idea of temporarily saving the Confluence page with no title, so the PDF is formatted the way you want it. Cue the theme song from the X-Files, please. Even though you
- cut the title
- save the page without a title
- generate your desired PDF
- re-save the page with the title restored; returning the page to normal
All, and I mean all, pages in that entire Confluence space will have the text of the deleted title inserted everywhere it see the carrot (^) link construct. Let me repeat … ALL pages will be so effected even though they have no relation to the page you edited, other than being in the same Confluence space.
There is no known fix. Well, there is a secret pill to avoid this bacteria … don’t create a Confluence wiki page which doesn’t contain a title. There, you’ve been inoculated.
Raptivity can be a good solution for faculty who want to create e-learning modules quickly without having to invest a lot of time and money into building customized applications or tools. The tool does still require some investment ($296 to $12500) depending on the amount of licenses and types of modules needed, but anyone can get started at the base level (only 12 interaction module types) for $296. However the Raptivity Essentials package ($500) includes 35 interaction module types, offering more flexibility for the price.
The Raptivity software allows for the instructor to publish interactive modules in Flash (SWF file format). You can easily track completion status, score, and responses for each interactivity because Raptivity creates SCORM compliant modules. Additionally all 35 of the interaction with the Essentials pack meet Section 508 guidelines for accessibility.
Raptivity utilizes a library of pre-built interactions that are completely customizable without needing to know programming. These pre-built interaction include templates for puzzles/games, presentation aids, and surveys that can be used in any e-learning environment.
Different “Turbo Packs” can be purchased to add functionality and new interaction types to the core Raptivity software. One of these is the HTML5 pack that allows for publishing interactions not only in Flash, but HTML5. This means that the same interaction can be played on an iPad or iPhone in HTML5 along with mobile devices with Flash Player support.
The only limitation to getting started with the software is that you will need to use a WIN system to create the modules. However all created modules will also playback on a MAC system with the Flash Player installed. Raptivity version 5.5, 5.6, and 6.0 are fully compatible with Windows 7, but the new 6.0 version is needed to work with creating HTML5 and mobile interactions.
The Google Art Project is a collaboration with some of the world’s top art museums. This site enables people to see many artworks online in very high detail. No longer do viewers have to wait in line to see some of the most popular pieces. The Google Art Project offers an alternative way to see these famous artworks, in greater detail and with a better view than you would have of these works in person.
Currently the Google Art Project allows for virtual visits of 17 of the world’s most well known galleries and museums. You can view 7,000 megapixel versions of over 1050 artworks. Some of the galleries and museums include are: The Metropolitan Museum of Art in NYC, The National Gallery in London, and The Uffizi Gallery in Florence.
This site has great potential for education, because it allows students who may never be able to see these works up-close and personal the opportunity to see them in high detail. Visit the site and let us know your thoughts in the comments below.

Adobe Connect recordings have historically been pesky to work with. Until recently, they couldn’t even be edited. Now, there is a way to give other users an exact copy of your Connect recording, and to make archive copies for yourself.
The steps below will walk you through the process of creating a copy of an Adobe Connect recording:
1. If the recording you want to copy is private, make sure you are logged in at http://gomeet.itap.purdue.edu with an account that is authorized to view the recording (usually only the meeting owner is authorized). If the recording is public you can skip this step.
2. Add the following on to the recording URL: “/output/filename.zip?download=zip” so that the whole URL looks like this, for example: https://gomeet.itap.purdue.edu/p10101010/output/filename.zip?download=zip
3. Paste the URL into your browser address bar and press enter.
4. Save the resulting zip file on your computer.
5. Log in to http://gomeet.itap.purdue.edu/ with the account of the person you want to own the copy of the recording.
6. Click on “Content” below Purdue.
7. Click the “New Content” button.
8. Beside “File,” click “Browse.”
9. Find and select the zip file you saved in step 3.
10. Give the recording a title, and enter a custom URL if you wish.
11. Click “Save.”
12. After a short processing time, you will see the content information page for this new piece of content.
The new copy of the recording will be identical to the original. There is no loss of quality during this process. However, because the new copy is in the content area, you cannot use the online Edit or Make Offline tools on the recording. Only original meeting recordings have these options available.
