A random thought on innovation: It is often less profitable to consider how new technology enhances existing applications than to find new niches.

What applications does GUI do so poorly that either no one has tried a solution or operators are paid over $100/hour for it?

Heavy Data Input/Reliance on the Visual

It's an inconvenient truth that Keyboards aren’t going anywhere. How long did it take you to learn QWERTY? Would you put that effort into a new interface? Probably not.

This viewpoint misses the great opportunity for multitouch and what Apple calls “Data Fusion”. Keyboards were originally laid out to be clumsy and to slow down data entry…because machines couldn’t keep up with our fingers.

Might there be a touch screen data entry solutions that’s better than keyboards? For what applications?

Here's a nice variation on touchscreen keyboards:

If a better data entry mechanism isn’t possible, how about a contextual keyboard, similar to Art Lebedev’s

It would be easy to layout an inexpensive, translucent keypad that could act as a projection screen, go on top of touchscreen and provide tactile feedback on top of a device like this...

In an off note, see the minimal angle on this table. This will make it much easier to use on an extended basis.

Reliance on the Physical

“The broader and more physical the gesture, the harder it is to do.”

This is the core problem with “drag and drop” solutions…is there a way for users to efficiently combine commands before entering them?

Inappropriate for the Context

This is the #1 issue that I see Surface Developers ignoring.

The physical environment that surrounds a product like Surface is the key to adoption.
When I was working on banking kiosks, we discovered that issues that had nothing to do with the device or software had a significant impact on adoption:
- People walking behind users
Flat overhead lighting
- Music/auditory feedback

Paco Underhill’s Why We Buy is a great book to start learning about these issues.

  1. Thanks for following GestureTek, inventors of video gesture control technology and 20-year leaders in the field. It's sad that Reactrix went under, but to clarify, Reactrix did not license Gesturetek technology. They licensed our patents in order to do business, as many companies do. Glad you noticed our 3 YouTube postings, as well. These are good examples of GestureTek's gesture control technology in action, but they are just the tip of the iceberg. GestureTek produces about 20 installations per month worldwide. Regarding our patents, the earliest of our patents does not expire for quite some time. We have more than 10 patents covering video gesture control technology and many more on the way.
