Dancer Test



Are you left-brained or right-brained? Supposedly, your brain lateralization determines how you view this animation.

Some people see her rotating clockwise. Others see her rotating counter-clockwise. Some see her unpredictably changing the direction of her rotation.

Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained.

I originally came across this animation here.

Anybody is free to do any suppositions.
But when everybody is doing the same supposition, it is taken almost as fact.

Why not make similar left/right brained supposition on the Necker cube?

The direction of rotation is both clock and counter clockwise.

I think there is no trick here .... or no optical illusion.

It is quite straight foward ... changing direction...

Watch the animation for about 30-50 secs ... with the idea the direction is changing... you can actually see the instant of changing the direction...

I wonder this has anything to do with left-right brain....

Shrini, not everyone sees a change of direction when they view the dancer. For example, I almost always see her rotating clockwise. My girlfriend, on the other hand, sees the dancer changing direction every few seconds.

Right .... I agree that people see the image differently. I am interested in knowing how do you relate these variations to compartmentalization of brain?

>>>Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained.

What about people who see neither? Like me - who see that the direction simply changes at about 10-20 secs.

I am interested to see how you make the connection?

Presumably, Shrini, the more often someone sees the dancer switch directions, the greater the balance of their left and right brain.

However, note that I wrote "supposedly" in the original statement and "presumably" in this most recent statement :-)

I don't know how valid the science is, but it's definitely interesting how different people see the dancer differently.

Why Spreadsheets Suck for Prioritizing

The Goal As a company executive, you want confidence that your product team (which includes all the people, from all departments, responsible for product success) has a sound basis for deciding which items are on the product roadmap. You also want confidence the team is prioritizing the items in a smart way. What Should We Prioritize? The items the team prioritizes could be features, user stories, epics, market problems, themes, or experiments. Melissa Perri  makes an excellent case for a " problem roadmap ", and, in general, I recommend focusing on the latter types of items. However, the topic of what types of items you should prioritize - and in what situations - is interesting and important but beyond the scope of this blog entry. A Sad but Familiar Story If there is significant controversy about priorities, then almost inevitably, a product manager or other member of the team decides to put together The Spreadsheet. I've done it. Some of the mos

Interaction Design: the Neglected Skill

Your product development organization has a big, gaping hole in it. (Be prepared to feel defensive as you continue reading.) One of the most important roles in product development is the role of interaction designer. An interaction designer designs how the users will interact with the product and conceptualize the tasks they perform. He decides whether, for example, the user interface will be command driven, object oriented (clicking on objects then specifying what to do with them), or wizard based. The interaction designer decides the individual steps in the use cases. Every company has one or more people that play the interaction designer role. Usually, those people have little or no expertise in interaction design. Sadly, they typically don't even realize how unqualified they are. Let's see who typically plays the role at companies. Engineer . An engineer is an expert on building what is designed. Yes, an engineer may know how to design the internal structure of the hardware
