Different ways of encountering an object
Spatial, acoustic and analytical views make different aspects of the same object available.
Explore in context
A geographic interface places an instrument in a landscape of places and relationships. A three-dimensional view instead offers a spatial representation of the object itself. Neither perspective replaces the source record.
Listen and interact
A playable representation can relate actions to sound, while an auralization can explore the role of a room or listening position. Each depends on a particular dataset and model, and needs to declare those dependencies.
Keep capability explicit
VAO profiles allow a package to declare the experiences and resources it actually supports. A viewer should respect those declarations rather than implying that every object provides playback, augmented reality or a complete simulation.
Cuntz · Released record#
Does showing the organ in 3D mean the VAO is playable?
A profile names a set of requirements for a capability. A client’s support describes what an application can do with the object; the two declarations must be compared.
Work through the example 3 STEPS
The Cuntz manifest declares Core, Dynamic Delivery, Playable, Physical Instrument, Scientific, Multimodal, Spatial and Zenodo Repository profiles under VAO 0.5.0.
Read the object’s declarations
The object contains information for several uses, including physical topology, scientific observations and sampled interaction. These requirements describe the package contract.
State the viewer’s operation
The notebook loads a GLB display derivative and provides camera controls. It does not import the full VAO manifest, evaluate its scientific records or execute its keyboard and stop behavior.
Choose another client when the task changes
To test sampled playback or synchronized controls, choose a client whose documented version supports the relevant format, profiles and resources. Record the tested operation separately from successful visual loading.
BASIS FOR THIS EXAMPLE
- Cuntz Positiv · VAO 0.5.0-rc.2 ↗
Published manifest: identities, measurement observations, realization digests, profiles and rights. Exact examples checked against this release.
- VAO Standard 0.5.0 ↗
The standard contract is separate from the Cuntz dataset content version 0.5.0-rc.2.
No acoustics profile or calibrated acoustic response is inferred from the presence of an organ model.
The useful distinction. A working 3D preview proves that the chosen model can be displayed; it does not establish complete VAO conformance or playability.
Different experiences answer different questions
| Experience | What it makes accessible | What to inspect |
|---|---|---|
| Geographic browsing | Place and regional relationships. | Location precision, dates and collection coverage. |
| Three-dimensional inspection | Visible form, spatial relationships and selected geometry. | Scale, reconstruction status and capture basis. |
| Sampled playback | A mapping between controls and recorded resources. | Instrument state, sample coverage, tuning and transformations. |
| Auralization | A modelled listening situation. | Source, room, receiver and model assumptions. |
| Signal analysis | Measured properties of selected recordings. | Input region, parameters and interpretation scope. |
Combining these views can make the research easier to explore. The combination should also preserve their differences: rotating a model is not evidence that the same representation supplies a validated acoustic simulation, and a plausible sound does not establish that its control mapping recreates historical playing conditions.
Let unavailable capabilities remain visible
An interface can show what a package supports, what requires another resource group and what the current runtime cannot execute. That makes a limited but honest experience more useful than a control that appears to work while silently substituting content. Users should be able to return from an interactive action to the resource and interpretation on which it depends.
Evaluate the claim made by the experience
Use technical tests for technical claims and appropriate empirical methods for perceptual or historical ones. Latency, signal agreement, package conformance and a player’s judgement of touch are different observations. The thesis’s technical demonstrations support bounded implementation and analytical claims; they do not replace participant studies of listening or playability.
