Introduction

This articles summarizes some ideas and examples about physical visualization, in particular with respect to project management and related areas. It is linked to our interest for 3D printers in education.

The absolute best resource page is physical visualization made by the Aviz project. In this page, we just focus on Lego visualizations that are weakly or strongly related to management of projects.

Token-based constructive visualization

Huron (2014b) [1] “asked people to create, update and explain their own information visualizations using simple materials such as tangible building blocks. We learned that all participants, most of whom had no experience in visualization, were readily able to create and talk about their own visualizations.” (Overview, retrieved July 2016). Based on a close observation on how people did build representations with tokens - for more information, consult the project website - the authors define a "token-based" visualization method, that they describe as follows:

To construct a visualization the necessary components are:

  • A set of basic units or tokens, which can be mapped to data,
  • A token grammar, which declares how the attributes of the tokens can signify data,
  • An environment in which the tokens can be placed,
  • An assembly model, which describes the constraints and freedom with which the tokens can be assembled.
The process of developing the constructed visualization starts from initializing the environment in which the construction will take place. Then the data units are mapped to the tokens and the tokens visual attributes are assigned meaning according to the data. These tokens are then assembled in the environment. Changes in data can subsequently be expressed by manipulating the data token.

Lego-powered time-tracking

“an alternative way to represent time schedule tracking by stacking different lengths of Lego blocks as a way to convey different sequential time periods. stacking hourly rows on top of each other builds up the whole day, while color represents the different projects at hand. a whole week of time tracking is created by setting up a series of rainbow-colored days.” (Lego-based time-tracking, retrieved nov 22, 2012)

Michal Hunger, in his On LEGO Powered Time-Tracking blog post describes how he uses it.

“I made up a single width column as ruler for the work hours (from at around 10 am up to 6 pm). So I can easily see whats missing and at what time I did something. For the days of the workweek I chose the rainbow color scheme (red, orange, yellow, green, blue – Monday to Friday) for the longer base row that I stack my hours on. So I can gather a whole week of time tracking until I have to enter them in some time sheet (software). I put the columns of a whole week on top of a green building plate to fix them.”

Benefits:

  • it works (for about 4 months now)
  • I have something to play with while pondering stuff
  • it looks great
  • it’s incredibly fast with no overhead
  • planning is possible

Yvonne Jansen et al. Empirical Investigation of Physical Visualizations

Data sculptures are an increasingly popular form of physical visualization whose purposes are essentially artistic, communicative or educational. But can physical visualizations help carry out actual information visualization tasks? But can physical visualizations help carry out actual information visualization tasks? We present the first infovis study comparing physical to on-screen visualizations. We focus on 3D visualizations, as these are common among physical visualizations but known to be problematic on computers. Taking 3D bar charts as an example, we show that moving visualizations to the physical world can improve users’ efficiency at information retrieval tasks. In contrast, augmenting on-screen visualizations with stereoscopic rendering alone or with prop-based manipulation was of limited help. The efficiency of physical visualizations seems to stem from features that are unique to physical objects, such as their ability to be touched and their perfect visual realism. These findings provide empirical motivation for current research on fast digital fabrication and self-reconfiguring materials.

Tangible Bug Tracking using LEGO bricks

The Tangible Bug Tracking project “is a practice to build a tiny structure which is representation of a software bug. Those are build with LEGO blocks and placed in the team’s workspace. LEGO bricks are represented as the priority, dependency, difficulty of software bugs by developer. It is a kind of information radiator.”. According to the author, Takeshi Kakeda, BUG-LEGO has three benefits:

  • Intuitive visualization of the quantity of software bugs for everyone.
  • Changing mindset of developer from negative to positive against software bugs.
  • Providing the physical constraint of the building plate.

The system uses the following representational elements:

  • Each bug is represented by a a Lego structure. A ticket ID is stuck on it with a PostIt
  • After a bug is fixed, the structure is destroyed.
  • Priorities are expressed with font/back positions
  • Severity and difficulty are expressed through the size and complexity of the Lego structure
  • Dependencies are also written on a PostIT that refers to the ID of the other bug.

Wable

“The personal feeds from webapplications like Plazes, Flickr, and Last.fm tell much about the activity of an individual on the internet. In this project we aim to explore how you can visualize the changes of your web identity over time and create a physical link between your virtual and real identity. The interface consists of both a physical table and a web application. This direct feedback from your web identity is customizable and can be connected to any RSS feed.” (Wable, retrieved nov 22, 2012).

3D Infographic Maps Built with Lego

“Samuel Granados has discovered an efficient way to display geographical data in 3D physical reality. Just use Lego [samuelgranados.es]. One side of the map reveals the emigrants of each zone, the opposite shows the immigrants (both represented by the volume of the pieces).” (3D Infographic Maps Built with Lego, retrieved nov. 22 2012)

Lego for visualizing production problems and health care management

“Now GM is using Legos for problem resolution tracking. If a transmission block breaks during durability testing, they’ll file a traditional paper report, but the case will also be added to a Lego board. Legos in various colors denote the area of the vehicle, and the block size denotes the severity of the problem.” (How GM Is Saving Cash Using Legos As A Data Viz Tool. retrieved nov. 21, 2012)

“WellStar is using the boards to track on-time starts at the doctor’s office, and even manage its physician-payee relationships--which has led to a series of fixes projected to save the company $1 million.” (dito)

Data as wood sculptures

Got and grow (plants)

Botros et al. (2016). [2] investigate “how a plant—a living visualization—whose health relies on the plant owner’s level of activity, can engage people in tracking and self-reflecting on their fitness data.”

This design is driven by the following design criteria:

DC1 - Abstract representations are more efficient than typical barchart-like visualizations for self-reflecting on personal data [5, 6, 22].

DC2 - Aesthetic, playful, and pleasurable representations engage people with everyday data and trigger emotions

DC3 - Goals that affect the representation leverage successful cognitive behavioural strategies

DC4 - Representations that can be shared leverage the benefits of the social context on engagement

DC5 - Representations that trigger emotional commitment favor both short-term and long-term engagement

DC6 - Non-virtual living representations leverage both physical metaphors and living plant metaphors, as well as the sustainable interest for living things

(preprint, page 2)

Results show that, “Overall, participants increased their awareness of their activity level. During the three weeks of the study, participants also changed their habits towards a more active lifestyle.” (p. 4)

A very different perspective is to use lego building as substrate for team building, management, etc. E.g.:

Research groups and people

  • Aviz is a multidisciplinary team of INRIA aiming at improving the analysis and visualization of large and complex datasets by combining analysis methods with interactive visualizations
  • socialbits.org is an international research group based in Linz (Austria), New York (USA), Vancouver (Canada), Melbourne (Australia) and Tokyo (Japan) focusing on the artistic output of social interactions in real world locations; specifically in urban environments, public spaces and unique architectural complexes. For example, “Urbansphere Wearables aims to reflect the daily keywords of the city by utilizing the data streams of social networks as a source of fashion design. The project initiates “social sensors” (special filters and data gathering scripts that follows Twitter) in order to collect information on social networks created by different inhabitants of the same city. The data gathered is then visualized and turned into a pattern for wearables that represent the recent topics and discussions of urban people. In the exhibition, visitors will see a set of unique wearables that contains data from İstanbul.” (retrieved nov 23, 2012)
