Custom Fiber Optic Handhelds

We've made a wide range of special response devices for around the same cost as our standard handhelds. We can accommodate most special requests using the standard fORP interface unit (up to 8 buttons or 4 buttons and two rotational/force axes). The outputs can be modified to accommodate most task

Sliders

Sliders have a wide range of configuration options including:

• Digital or analog data output.
• With or without detents.
• Center, left or right position to start.
• Variety of return to origin, from strong pressure to no pressure.
• Up to 4 buttons can be included.
• A variety of compute outputs available.
• Priced like standard handhelds.

Two examples:

This slider has a detent in the center and two buttons.	This slider has no detents but a strong return to origin.

Dials and Wheels

Rotational sensors also have a wide range of characteristics:

• The type of wheel can be large or small.
• It can be a continuous analog output or a incremented values.
• Up to 4 buttons can be included.
• A variety of compute outputs available.
• Priced like standard handhelds.

Two examples:

A large knob which can be turned an unlimited number of times.	This scroll wheel is also a button when depressed.

Grip Force Transducer

This grip force transducer gives linear
output based on the pressure applied,
with a range of 100N.

Special Button Boxes

While our standard button boxes are optimized for most people, there are some subjects who have special requirements.
We can work with you to develop custom handhelds that will work well for a specific task.

• Modify the buttons to make larger or smaller.
• Add varying indentation.
• Change the spring force so more difficult to accidentally push.
• Change button placement.
• Add a fifth button, including on the side or back.
• Priced like standard handhelds.

An example of a custom 5-button handheld with the thumb button on the end.	Cupped buttons and double springs make the buttons less sensitive for for subjects with tremors.	Large button caps are attached for subjects with limited finger movement.
