In the 19th century, the Torres Strait Islanders did not have a numeral system and used sticks to keep counts. Sticks were tied to a string, forming a bundle (called kupe) that could be rolled and unrolled when needed. Kupes were typically used by men to keep track of their accomplishments, such as turtles caught in deep water, fishes speared, or adventures with women (as the one above). These physical visualizations were used as social displays, and big kupes were greatly prized. According to […]

Women from the Yakama Native American tribe used strings of hemp as personal diaries. Each major event in their life was represented by a knot, a bead or a shell. This mnemonic device is called an Ititamat, or counting-the-days ball, or simply time ball. The first image shows an Ititamat created before 1920. On the second image, each string is a different Ititamat. The last image shows a 2003 replica. A young woman would use a time ball to record her courtship, marriage, and other experiences […]

Slumber was a multi-year gallery installation/performance by artist Janine Antoni. From the website description: Performance with loom, yarn, bed, nightgown, EEG Machine and artist’s REM reading. Antoni transforms the fleeting act of dreaming into a sculptural process. Between 1994 and 2000, the artist slept in the bed while an electroencephalograph machine recorded her eye movement. During the day, Antoni would sit at the loom and weave shreds of her nightgown in the pattern of her REM. The […]

American artist Cory Imig reconstructed the layout of the city of Savannah using LEGO bricks, and over the course of one month she added a colored brick every time she went to a particular place. Each color is a different day of the week. Source: Cory Imig (2008) Psychogeographical Mapping (see the section Documenting of her Web page for more data sculptures).

A visualization and logging method for personal work activity. Every tower is a day of the week. A layer is one working hour, horizontally subdivided in four quarters of an hour. Different colors are different projects. The constant availability of this interface makes it easier to log personal activity data on-the-fly, before entering it in a PIM software (an automatic method involving computer vision is being considered).

In his experiments with visualizing data from Tripit to look back at his own (and other people's) travel, Cemre Güngör came up with a new system to create data sculptures from one's travels over time. This work is of a particular interest, in that it shows an excellent example of how a physical visualization design process unfolds, with many questions unique to physicalization add up to the challenge of designing an effective visual representation, i.e., contrasting materials and treatments […]

Alice Thudt, a PhD student in Computational Media Design, crafts pieces of pottery that embody data about moments she shared with her loved ones. Left image (2015): cereal bowls showing Skype-call history between Alice and her parents. On the front bowl, each line represents a day where they skyped. On the other bowl, each dot represents 10 min of call time. She offered a bowl as a present to her parents and kept the other one as a reminder to stay in touch every time she has breakfast. Middle […]

Wearable Self is a collection of data jewelry which is Jiyeon Kang's master's thesis project at Parsons School of Design. South Korean designer Jiyeon Kang transformed a year of self-tracking data (e.g. daily steps) gathered by Fitbit and iPhone Health into personalized fashion items that can hold and wear. Through laser cut and 3d printing with different materials, the designer creates customizable fashion items generated by users' self-data, aiming to make self-tracking data more meaningful […]

A visualization of my son's sleep pattern from birth to his first birthday. Crochet border surrounding a double knit body. Each row represents a single day. Each stitch represents 6 minutes of time spent awake or asleep. Also see our entry 2013 – Temperature Scarves and Afghans. Source: Seung Lee (2019) Twitter thread.
