“wow” and “cool”. These immediate responses can be misleading as to the
potential for longer term use. More reflective responses included:
•
I see correlations across sectors I wouldn't have expected to see. -
Company Analyst
•
This could be great for pairs trading. I need an easy way to pick one
item then flip the sphere around to the inverse for 10 choices to
trade against. - BC
•
Not only is it cool, it also shows a lot of data. It seems very
intuitive. - Stock trader
•
This can be useful to find quickly a subset of cheap correlated
individuals. - AH
•
I've never considered this on a sphere before: I'm excited about the
technique. And there are many ways that the technique could be
extended to additional variables of information. - Hedge fund

It's a good paradigm; it seems like you would want to animate it. -

•
Correlations on a sphere make sense. You could allow attributes
like depth, use zoom, or navigate into the sphere to see the backside
of the current view. - CF
•
This shows some interesting patterns very well. For example, when
there is a strong cluster, the trader has many stocks to choose from,
but when there is an isolated security with no close neighbours you
see immediately that there are no immediate alternatives. - Risk
Manager
Feedback also included concerns and hesitation regarding using the 3D
interface; for example:
•
This interface could overwhelm a casual user. For a casual user you
want a way to centre on a security and maybe flatten it out. -
Advanced derivative user
•
How do you click and drag to select multiple items? - Stock trader
•
Why does it keep turning, why can't I just pick an item and keep it
in the centre. - Risk Manager.
SphereTree was not specifically evaluated with this audience, as
hierarchies can be addressed in part using many existing techniques,
including pivot tables, expand/contract dialogues, treemaps [Joh91],
sunbursts [Sta00], or variants on sunbursts in use in financial markets
today. SphereTree represents the feasibility of transforming a technique
