Live TuningExpanding Live Programming Benefits to Non-Programmers
Live Programming allows programmers to gain information about the program continuously during its development. While it has been implemented in various integrated development environments (IDEs) for programmers, its interaction techniques such as slider widgets for continuous parameter tuning are comprehensible for people without any prior knowledge of programming and have been widely used for a long time.
In this paper, we aim to introduce prior work on Live Programming research from the interaction point of view and relate it to Human-Computer Interaction research. We then name the subset of Live Programming interaction that only involves changes in constant values "Live Tuning." Our example IDEs that implement both Live Programming and Live Tuning interactions are showcased, followed by the discussion on the possible future direction of programming experience (PX) research.
Because programmers are tired
- There are more and more data-intensive programs such as animation design, IoT application development, machine learning, etc.
- The amount and variations of data far surpass what programmers alone can manage and edit. Intensive parameter tunings might be needed per user.
Because users are demanding
- Live Programming (changing program behaviors without losing context) can benefit end-users. In particular, they can comprehend parameter tuning interfaces and customize programs to match their needs.
- They typically do not have access to development environments since they lack prior knowledge of programming.
- Interaction design forprogrammers, typically built in development environments
- Prior knowledge of programming is required.
- The entire programs are always live and editable.
- The programmer has full control and is responsible for every aspect of program details.
Example "Live Tuning" IDEs
Please refer to the paper (p.4-6) for the detailed discussion. Underlined options are those we consider the most interesting and promising.
- Programming environments (for programmers) are getting close to runtime environments (for end-users). Live Tuning is such a proposal to connect them through the tuning interfaces.
- Multiple levels of user interfaces allow varied flexibility to edit programs. Live Programming aims at the maximum flexibility and Live Tuning is somewhat in the middle between no and maximum flexibility.
- How can we resolve or avoid conflicts between edits by multiple users? 1) seriously implement conflict resolution mechanisms 2) discard old edits as typical Live Programming systems do 3) separate namespaces and resulting application instances 4) aggregate parameter values from different users.
- How can we achieve liveness when it takes time to apply edits? For instance, updating the 3D models is an instant process, but printing them takes time. 1) significantly progress the research of programmable matter 2) hack humans' feeling of liveness.
