Touch
The Touch is a compact, precise motorised haptic (force-feedback) device designed to deliver realistic force feedback when manipulating digital virtual objects.
Thanks to its ergonomic stylus and pressure-sensitive touch system, it gives users a natural interaction with digital environments, allowing them to “feel” the shapes and textures of the objects they handle.
- Realistic haptic feedback that lets you “feel” virtual objects and perceive their textures and rigidity.
- High movement precision, with a nominal resolution of 0.055 mm (450 dpi).
- Intuitive interaction thanks to natural hand tracking pivoting at the wrist.
- Ergonomic stylus for comfortable use during long sessions.
- Compatibility with many design software packages (including Geomagic Freeform and Freeform Plus).
- Simple USB connection, quick calibration.
Based on an articulated mechanical arm connected to a stylus, the Touch converts hand movements into digital data while generating proportional feedback. The user thus perceives resistance, textures and volumes as if handling a real object.
With 6 degrees of freedom for position and 3 degrees of haptic feedback, it ensures high precision and a workspace of 431 × 348 × 165 mm (W x H x D), ideal for complex projects.
Combined with software such as Geomagic Freeform or Freeform Plus, it enables organic modelling, digital sculpting and virtual assembly. Reliable and easy to integrate, the Geomagic Touch adapts to medical modelling, simulation, virtual reality and 3D printing environments.

Medical applications
The Touch is used in a variety of medical applications thanks to its realistic tactile feedback and high precision:
Surgical simulation and medical training:
Reproduction of technical gestures in a safe, realistic environment.
Custom orthoses and prostheses:
Digital design with a genuine tactile feel, making it easier and faster to prepare models for 3D printing or machining.
Surgical planning:
Planning of procedures based on consistent digital models.
Design of surgical guides and implants:
Coupled with the Geomagic Freeform and Freeform Plus CAD software, the Touch enables “organic” design suited to patient-specific devices.
Podiatry and ergonomics:
Detailed morphological analysis along each axis of movement.
How does the Touch work?
Using it follows several simple,
structured steps:
-
1
Connect the device via USB port and install the driver,
-
2
Calibrate the mechanical arm and the stylus,
-
3
Choose compatible software (e.g. Geomagic Freeform, Freeform Plus or other modelling / simulation / programming software),
-
4
Handle the stylus: every hand movement is translated into digital data,
-
5
Benefit from real-time haptic feedback, conveying textures, rigidity and friction as with a real object.

Reviews and user feedback
User feedback highlights the precision and realism of the Touch’s haptic feedback. Practitioners appreciate being able to feel textures, rigidity and friction in real time, which makes modelling more intuitive and improves the quality of their designs.
The ergonomic stylus is also praised for its comfort during long sessions, particularly in surgical training or surgical planning.
Finally, compatibility with software such as Geomagic Freeform and Freeform Plus is seen as a major advantage, as it facilitates the design of orthoses, custom prostheses and patient-specific surgical devices (guides & implants), as well as integration into medical virtual reality.
FAQ
The Touch connects easily via USB, with driver installation and an initial calibration.
It is used in healthcare (simulation, prostheses, training, surgical guides and implants), in digital design (Geomagic Freeform, product design), in robotics and in virtual reality.
The Touch arm is used with Geomagic Freeform, Freeform Plus and many other 3D design / modelling, simulation or teleoperation software packages.
A haptic arm is a motorised force-feedback system that allows users to regain a sense of touch and interact with virtual objects in the digital world.
