2. Existing Design Spaces for Physicalisations
3. Narrative Review: Encoding Variables for Physicalisations
4. Systematic Review: Encoding Variables, Evaluation Criteria, and Methods
4.1. Searching and Retrieving Publications
“query”: Title:(“data physicalization”; “physical visualization”) OR Abstract:(“data physicalization”; “physical visualization”) OR Keyword:(“data physicalization”; “physical visualization”) “filter”: Publication Date: (1 January 2009 TO 31 March 2022), ACM Content: DL
(TITLE-ABS-KEY (“Data Physicalization”) OR TITLE-ABS-KEY (“Physical Visualization”)) AND PUBYEAR > 2008 AND PUBYEAR < 2023
4.2. Screening and Paper Selection
- Criteria 1: Articles that were not original peer-reviewed articles or that were not full papers (to ensure that the papers had a complete full scale evaluation of a data physicalisation) (e.g., late breaking works, workshops, pictorials, posters, speeches, doctoral consortium papers, etc.) were excluded.
- Criteria 2: Only the articles that discussed an artefact of data physicalisation and empirically evaluated that physicalisation were selected. Therefore, publications that introduced frameworks, theories, processes, opinions, methodologies, concepts, and reviews, as well as publications that did not empirically evaluate a physicalisation, were excluded.
- Criteria 3: Articles that discussed augmented physicalisations (for example, [77]) were excluded from the analysis.
- Criteria 4: Articles that discussed the same data physicalisation discussed in another article were removed, as our objective was to review different data physicalisation artefacts.

5. Systematic Review: Results
5.1. Evaluation Criteria and Methods
5.2. Connecting Evaluation Criteria and Utilitarian/Casual Intents
- Criteria used for physicalisations with a casual intent: intellectual engagement, social engagement, affective engagement, the potential for self-reflection, motivational potential, creativity, user’s reactions, quality of the design, potential for self-expression, quality of the information content, aesthetics, and remote awareness of physiological states.
- Criteria used for physicalisations with a utilitarian intent: effectiveness, efficiency, size judgement, confidence, and orientation consistency.
- Criteria used for both types of physicalisations: user experience, utility, understanding (qualitative), attitude change/behavioural stimulation, memorability, enjoyment/satisfaction, ease of use, design parameters, learning curve/ease of learning, social acceptance/ease of adoption, and physical engagement.
5.3. Representation Dimensions
5.3.1. Lessons Learned about the Encoding Variables
- Physical variables: Material should be added to the list in addition to the properties of the material. A nice example can be found in [66], which used the tokens’ material (folding paper vs acrylic) to differently encode information related to the core academic background and the additional academic interests of the users.
- Haptic variables: The list of haptic variables that are derived from visual analogues can be extended with at least two variables: Tangible arrangement (variations of the distribution of individual marks that make up a symbol) and tangible numerousness (arrangement combined with size), as both can be perceived through touch. For instance, the number of squares and their size were used in the ‘Dressed in Data’ clothes to communicate data about indoor air chemicals, and this resulted in a lace pattern [46]. That lace pattern (both the arrangement of the squares and their numbers) can be perceived by touch. This is an example of both tangible arrangement and tangible numerousness.
- Dynamic variables: The list of dynamic variables should be extended with change pattern (variations in animation/movement patterns used to communicate change) as a new variable. For instance, the PhysiMove physicalisation [78] used counterclockwise movements to indicate decreases in value, clockwise movements for increases in value, and no movement for the lack of change; Keefe et al. [93] used different animation effects to communicate the occurrence of different weather events (i.e., rain, snow, and cloud cover) and Pepping et al. [71] used the slow/fast fading of LED lights to communicate whether or not an emotional experience was positive/negative.
5.3.2. Interrelationships between Dimensions
- Form the intention (goal/purpose) of the representation (casual, utilitarian, see Section 4.4);
- Select a dataset (categorical, ordinal, numerical, or a mix of these);
- Choose the representational fidelity (iconic, indexical, symbolic, or dynamic, see Section 4.4);
- Choose a material (examples in Section 3);
- Pick the encoding variables (examples in Section 3). The choice of the encoding variables entails the choice of sensory modalities.
- Evaluate the artefact (examples in Section 5.1).
- Intent—dataset (p-value < 0.001; Cramér’s V = 0.67): There were differences in proportions for nearly all types of datasets. Most notably, physicalisations with a casual intent used the combination of categorical and ordinal and numerical datasets more often than those with a utilitarian intent; they also used numerical data much more often than those with a utilitarian intent. The nonrandom association observed here could be due to some bias in the sample: all physicalisations where the type of dataset was ‘not documented’ were those having a utilitarian intent (these physicalisations were used to investigate the theoretical properties of physicalisation in [17,67,99]: orientation consistency, size judgment, and graph physicalisation).
- Dataset—material type (p-value < 0.001; Cramér’s V = 0.65): Physicalisations encoding three types of datasets (categorical and ordinal and numerical) all used electronic material. The nonrandom association observed here could also be due to some bias in the sample: all physicalisations where the type of dataset was ‘not documented’ were those using non-electronic material (investigation of theoretical properties).
- Dataset—representational fidelity: The Fisher’s exact test between the data type and the representational fidelity was not significant. Nonetheless, the association between the number of datasets and the fidelity was significant (p-value = 0.01; Cramér’s V = 0.46). In particular, there was no physicalisation with two/three datasets that had an indexical fidelity (i.e., the physicalisation bore a direct relationship [physical or causal] to the data being represented) in our sample.
- Material type—encoding variables (p-value < 0.001; Cramér’s V = 0.69): Physicalisations combining variables beyond the visual and haptic dimensions (e.g., visual and sonic and haptic and olfactory) all used electronic material.
- Representational fidelity—encoding variables: The Fisher’s exact test was not significant.
- Encoding variables—evaluation criteria: We grouped the evaluation criteria into three categories: traditional, novel and traditional and novel. ‘Traditional’ refers to the criteria above the dashed line (except physical engagement), whereas ‘novel’ refers to physical engagement and criteria below the dashed line. The Fisher’s exact test was not significant.
- The Cramer’s V between n_modalities/variables, n_datasets/data_type, and dynamicity/variables was 1 because the dimensions were derived from one another. In particular, n_modalities counted the number of encoding variables used, n_datasets counted the number of data types used, and ‘dynamicity’ documented whether (or not) dynamic variables were part of the encoding variables.
- Only non-random associations between two consecutive dimensions are highlighted in Figure 5. Nonetheless, the data suggests that there were more non-random associations (e.g., intent/evaluation, intent/data, and data/material). Overall, the material dimension exhibited significant correlations with other non-derived dimensions most often (4/5: intent, evaluation, variables, and data type), followed by the data type dimension (4/5: intent, evaluation, variables, and material) and the intent dimension (3/5: evaluation, data type, and material). The fidelity dimension correlated with other non-derived dimensions the least often.

Appendix C. Definitions of Evaluation Criteria
- Intellectual engagement [23]: Refers to the ability to engage the user in intellectual activities such as recognition, analysis, and contemplation.
- Social engagement [23]: This is present when observers talk with companions, but also when laughing, gesturing, and mimicking the body postures of others. It was assessed, for instance, in [83] through the use of a confederate.
- –
- Confederates are individuals recruited by lead experimenters to play the role of a bystander, participant, or teammate (see e.g., [120]).
- Affective engagement [23]: Refers to the emotional experience of users. The arousing of feelings such as awe, respect, wonder, concern, fear, disgust, anger, or intimidation are indicators of an affective engagement.
- Engagement over time: The evolution of engagement over a given time period.
- User experience [100,101]: The review of definitions by Law et al. [101] pointed out that the ISO definition of UX,“A person’s perceptions and responses that result from the use or anticipated use of a product, system or service”, is in line with what most UX researchers associate to the concept. In essence, UX refers to all aspects of the users’ interaction with a product. It has pragmatic attributes and hedonic attributes [100].
- Effectiveness (question answering) [103]: In the sample analyzed, effectiveness was measured through the accuracy with which participants completed information retrieval tasks [6,89] and interaction tasks [96].
- –
- Information retrieval tasks are specifically directed at retrieving information (e.g., cluster, maxima, or minima of a dataset), whereas interaction tasks are more open-ended (e.g., data analysis tasks such as annotation, filtering or navigation). Hence, not every interaction task is an information retrieval task.
- Potential for self-reflection: This is the ability of the physicalisations to prompt users to think about themselves. Thudt et al. [113] identified four types of personal reflection in the context of data physicalisation: reflection on (their) data, reflection on (their) context, reflection on (their) action, and reflection on (their) values.
- Attitude change/behavioural stimulation: This refers to the extent to which a physicalisation can change the attitudes of users (e.g., do they care more about a given subject?) or inspire them to take some action [83].
- Memorability [7,82]: Memorability has different facets, for instance, recognition or recall (see [121]), explicit or implicit memorability (see [7]), and the storage of information in short-term memory or long-term memory (see [122]). It is the capability of maintaining and retrieving information [82].
- Motivational potential: The ability of the physicalisation to promote gradual changes in individuals’ behaviour or sustain the changes over time. It was evaluated through self-developed questionnaires [95].
- Ease of use: The perceived ease of use.
- Design parameters: sSme studies intended to find optimal design parameters and conducted a systematic evaluation of these parameters to that end. For instance, Daniel et al. [89] systematically varied motion speeds to find out the best speed to animate the CairnFORM physicalisation. López García and Hornecker [92] systematically varied the size of two physicalisations and assessed the impact of these changes on ease of viewing and understanding.
- Learning curve/ease of learning: This refers to the perceived learning curve.
- Social acceptance/ease of adoption [70]: this refers to participants’ opinions about the possible introduction of the physicalisation in their lives or sentiments regarding the ease of adoption of the physicalisation.
- Size judgment: Although this was assessed primarily through the accuracy of participants on information retrieval tasks in [17] (and, hence, could have been said to belong to the assessment of the effectiveness of the physicalisation), we still kept this criterion as separate, because it is important for the development of theories of perceptual effectiveness of variables. Ratio estimation [123] and constant sum [124,125] are two methods to collect data about participants’ judgments.
- Confidence [70]: This refers to the self-reported confidence levels of users.
- Creativity [23]: The ability of the physicalisation to support the introduction of new and original ideas.
- Physical engagement [23]: It invites people to spend time touching and interacting with the data (even if just in imagination), moving around it to take different perspectives, bending down to read a label, and employing senses including smell and hearing.
- Users’ reactions: Some articles used the term ‘user reaction’ [88,96] or ‘ad-hoc impression’ [68] to refer to how the users react to a physicalisation. While there are overlaps with engagement (e.g., the user reactions mentioned in [96] could be classified as an assessment of physical engagement, and part of the reactions documented in [88] could be classified as an assessment of affective engagement), we still keep this evaluation criterion as distinct, because it could be useful for exploratory studies.
- Orientation consistency [99]: The consistency of user responses to information retrieval tasks across different orientations.
- Potential for self-expression: The extent to which the physicalisation can help users express some personal characteristics (e.g., academic profile or running performance). It has at least two components mentioned in [66]: representational possibilities (what the user can say through the physicalisation) and representational precision (how accurately they can say what they intend to say).
- Quality of the information content: Evaluated in [95] through self-developed questionnaires.
- Aesthetics of the physicalisation: This touches upon the appearance of the physicalisation. It was evaluated using self-developed questionnaires in [95].
