OBSTACLES

What stands between us and a pervasive programmable reality?

The technology is available!!! Top-down, discrete development flow

Design application, set up environment, write code, debug, compile, flash, evaluate, repeat.

Portability / Compatibility issues

Libraries, hardware versions, drivers, …

GOAL

Create a tool for programmable reality

Reality means everyone! Augmented reality hard to develop, easy to use How can we enable a programmable reality which is also easy to use?

Wireless sensor networks are a good starting point: post-hoc computing

BUT: Tremendous development energy required System complexity in terms fields of expertise required

EVALUATION

Simple evaluation of application development effort

Of the 5 subjects, none had any experience with BASIC Each student given 5 Minute syntax and functional introduction Subjects were asked to calculate and print the average of 100 received WSN temperature packets to the console

Time required for completion measured

RESULTS

Time

Minimum at 3:50 Maximum 7:11 Average time of 5:20

Implicit baseline: application on COTS Node? Interesting initial observations

Free text editor significantly more efficient Previous programming experience greatly effects learning curve, regardless of language

CONCLUSION

The age of programmable reality has arrived

The tools to bring it to the masses are still missing

The dinam concept is enabling technology for this paradigm

Non-expert user-friendly interface for configuring the Programmable Reality Reduces normal discrete programming to a fluid process

Workshop on ULC-WSN Output

Evaluation of the dinam concept for extremely low cost, low effort applications Insights

WSNs must be easy to install and maintain The killer app will reduce cost of its platform App stores can help cover costs

Indicate that the dinam concept will facilitate ULC-WSN development
