I’ve done a fair amount of work in interaction deisgn for data visualization in MI (management Information) and BI (Business Information) systems, mostly around setting graaphical data representation and interaction guidelines for such applications. One of the most basic things which people get wrong again and again is when [...]
Here are two human-centered healthcare concepts I have come up with and imagine will be true in the future where technology and service design are applied to not only make the health care experience invisible (concept 1) but fun and way beyond simply retaining the human element (concept 2).
Concept 1: The Phone of the Future- [...]

Heuristic evaluations and expert review have the same goal- to evaluate the usability of the product. While the goal of these usability evaluation methods is the same, the methods are different.
It is common to hear people people using these terms interchangeably. An expert review is termed as a heuristic evaluation when in actuality the evaluators evaluated the usability of the product referring to their own knowledge of right and wrong rather than explicitly referencing against a set of heuristics.
This article explains the difference between a Heuristic Evaluation and an Expert Review and tells you when to apply which method.
In this article, originally published at Evolt, I talk about the issue of accidentally activating the browser back button through the keyboard while interacting with a long web form that is applicable to users across expertise levels. The time and effort wasted by the user can be said as proportional to the number of input fields filled by the user before accidentally exiting the page.
Since no application feedback indicating cause of the error to the user is provided, depending upon user expertise, the user may or may not realize the cause of the error. Realizing what is wrong does not guarantee the possibility of reverting the error either.
This leads to unnecessary loss in form conversions despite favorable user intent. A solution to resolve this issue (that I hope becomes standard practice) to plug the hole for lost conversion that translates to big numbers in absolute terms for high traffic websites is also provided.
In this article also published at Usability News, I provide you with some tips to help begin finding usability test participants successfully on you own, in case you are not using the services of a professional recruitment agency or do not have an internal recruitment team that can help you acquire participants for usability tests.
A simple process you can utilize for conducting effective and efficient meetings (where you work in a framework that aims at accomplishing the goal of the meeting and time is well utilized) at your organization. You can also find a link to download the MOM (minutes of meeting) template at the end of the article.
