We’re excited to announce a new graphical design and interface for our emergency aids. We’ve adopted an object-action interface approach to our paper-based aids. This model emphasizes an object upon which we then apply an action. We hope this approach will simplify the interface and improve usability by defining tasks through object-action models.


Our object-action design model is fairly simple. We break a task down by first stating an object and then applying an action, e.g. STERNUM -> COMPRESS. This approach creates a more concise checklist that helps users rapidly find what they need and more quickly apply the appropriate action.

Our design strategy still involves breaking down the tasks of ACLS into sub-problems so they can be tackled in a systematic approach. You will see that we have organized the task hierarchy by their importance in ACLS, and enclose them in boxes.

Another design innovation for our Object-Action design is to separate tasks in the sub-problem boxes with white graduated separator lines. The addition of these separator lines improves vertical scanning of the aid for individual tasks.

We’ve also paired down graphics in the Object-Action designs to just the most essential pictographs needed to explain and improve task performance.

We hope you enjoy these new emergency aids! Look forward to an update of all of our existing aids to the new Object-Action design in the near future.

Invitation to Use and Share 

On behalf of the Stanford AIM lab, Dr. Kyle Harrison and myself are proud to offer these aids to the public under a creative commons license (to share and distribute, but not sell or modify). We look forward to comments from the public about how we can improve them. You can print a copy for your own use without charge.

A new paper-based booklet that fits in your pocket!


We are also pleased to announce the immediate availability of our Object-Action ACLS aids in a printed booklet that easily fits into scrub and white coat pockets. These booklets are on sale to the general public immediately. The booklet is printed in full color on high quality paper. If you are interested in ordering booklets, ($4.99 each + S&H, with discounts for bulk purchase) please contact us at Quantities are limited and we won’t be printing any more until mid-2015.

A new iOS app brings Object->Action! to your iPad


Another exciting development is the publication of our first iPad app. ACLS Emergency Aids is now available for download from the iTunes store free of charge. Please take a moment to download this new app to your iPad and let us know how you like it!

Finally, we invite you to join the CogAIDS community newsletter to stay informed of our progress as we continue to develop more medical cognitive aids.
