Hick’s and Fitt’s laws: Two important psychological principles to consider when designing navigational menu structures

Most web-based or mobile applications are organized in some type of hierarchical menu structure. Company information is usually located in an ‘about us’ tab, Products and Services each have a tab, etc.

Some company websites, for example, provide a menu structure that is initially simple, but then may require several more interactions to navigate down the tree to the target information.

EHR usability Gap - Specified Context of Use

The efficient and effective use of Electronic Health Records are essential, as these systems are increasingly becoming a central tool for patient care.

The Health Information Technology for Economic and Clinical Health (HITECH) Act provided providers with a significant financial incentive to increase the adoption and use of EHRs. EHR vendors were required to conduct and report on a summative usability evaluation of their system as part of the Stage 2 Meaningful Use program (The ONC 2014 Edition Certification) and beyond. However, a recent report funded by the Agency for Healthcare Research and Quality (AHRQ), identified several “issues” with the certified EHR vendors in the processes, practices and use of standards and best practices with regard to usability and human factors.

What happened to Apple's commitment to quality?

I just finished downloading and installing yet another update to the operating system on my Macbook.

People pay a premium price for Apple products and reasonably expect to receive a superior product. A MacBook pro costs $1,299. A comparable HP laptop (the EliteBook 745 ) starts at $749. A 9.7 inch iPad Pro (with 32GB of storage) costs $599, while a 9.7 Samsung Galaxy Tab S2 with 32GB is $499.

Alfred Hitchcock and the future of Health IT

In the classic Alfred Hitchcock film “Rope,” Hitchcock shot continuous scenes for periods lasting up to 10 minutes (the length of the film camera magazine), continuously panning from actor to actor. Every other segment ended by panning against or tracking into an object—such as a man's jacket blocking the entire screen, or the back of a piece of furniture.

In doing this, Hitchcock effectively masked half the cuts in the film.
