Lofelt Studio

Tool Summary

General Purpose Information
Year of First Releaseⓘ The year a tool was first publicly released or discussed in an academic paper.	2020
Platformⓘ The OS or software framework needed to run the tool.	Windows, macOS
Availabilityⓘ If the tool can be obtained by the public.	Unavailable
Licenseⓘ Tye type of license applied to the tool.	Proprietary
Venueⓘ The venue(s) for publications.	N/A
Intended Use Caseⓘ The primary purposes for which the tool was developed.	Haptic Augmentation, Collaboration

Hardware Control Information
Haptic Categoryⓘ The general types of haptic output devices controlled by the tool.	Vibrotactile
Hardware Abstractionⓘ How broad the type of hardware support is for a tool. Bespoke: Hardware is custom built, including open hardware. Consumer: Support is limited to a specific commercial device or a family of devices. Class: Any device with the same affordances can be used, possibly with some configuration required.	Consumer
Device Namesⓘ The hardware supported by the tool. This may be incomplete.	iPhone, Android
Body Positionⓘ Parts of the body where stimuli are felt, if the tool explicitly shows this.	N/A

Interaction and Interface Information
Driving Featureⓘ If haptic content is controlled over time, by other actions, or both.	Time
Effect Localizationⓘ How the desired location of stimuli is mapped to the device. Device-centric: No spatial information is taken into acccount. Actuators are directly controlled. Target-centric: Stimuli are placed on the body or are assigned to a virtual object to be triggered through interaction. The tool handles how the device will display the effect. Location-aware: The desired location of an effect is taken into account to some extent, but is ultimately presented in context of the output device.	Device-centric
Media Supportⓘ Support for non-haptic media in the workspace, even if just to aid in manual synchronization.	Audio
Iterative Playbackⓘ If haptic effects can be played back from the tool to aid in the design process.	Yes
Design Approachesⓘ Broadly, the methods available to create a desired effect. Direct parametric control (DPC): low-level parameters are directly modifiable. Process: parameters are controllable by an abstract process. Sequencing: reusable effects are ordered in time to create complex effects. Library: a library of pre-existing effects is available for use or re-use. Description: a natural language description of the experience is used to find an appropriate effect, often through searching a library.	DPC, Process, Sequencing
Interaction Metaphorsⓘ Common UI metaphors that define how a user interacts with a tool. Track: a timeline represents an interactive channel containing effects. Keyframe: key points of the effect are set and behavior between them is interpolated. Score: an adaptation of a musical score or notation represents haptic effects. Dataflow: a dataflow programming model is used to control haptic output. Demonstration: physical actions or other data are mapped simply to effects or parameters. Generic Menu: typical GUI elements (e.g., sliders) are used to control effects with the absence of other metaphors.	Keyframe, Demonstration
Storageⓘ How data is stored for import/export or internally to the software.	WAV, Internal
Connectivityⓘ How the tool can be extended to support new data, devices, and software.	API

Additional Information

Lofelt Studio allows users to load an audio file into the tool. This automatically creates an initial vibrotactile experience. This can be refined through controls in the editor itself, such as menus controlling global parameters and using keyframes to control the waveforms directly. These editing processes can also be used to create effects from scratch. Vibrotactile effects can be sent to iOS and Android devices with a corresponding Lofelt Studio app installed.
