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 Dawud Gordon

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
