The key is simplicity. Young children find moving the laser light easy to do. Adults who have suffered a brain injury often find moving a light easy to do. In fact, research has demonstrated that some people diagnosed with locked-in syndrome actually learn to move their head using our safe-laser technology.
The Safe-laser System provides a continuum of access options. Start out just pointing the light at a letter board or images and let a communication partner interpret what the point means. Then progress to a call button that lets someone know you want to tell them something and you point to letters while they interpret. Then, using dwell or a secondary switch, you can write out messages to the display, or access recorded speech on a key-by-key basis. You can also control the TV. It is all possible with the Safe-laser System simple light pointing, spelling, computer access, speech output, and environmental control.
What It Does For You
The Safe-laser System is incredibly easy to use - even for children who are very young or adults that have had a severe stroke. The laser provides "concrete" movement feedback and is eye-safe around people and pets. Our clinical collaborators have used the Safe-laser System to:
- Help people who have had a brain-stem stroke to relearn head movement
- Provide an easy to access "low tech" communication board accessed by light (laser) pointing
- Provide up to 60 minutes of digitized speech output
- Type messages on the display with or without word prediction
- Use the laser keyboard to control a computer, tablet, or phone through a USB cable or wirelessly via Bluetooth
- Select TV channels, turn on and off the lights, or operate an automatic door opener
While the Safe-laser System can be used "stand alone" or to interface to computers, tablets, and phones as a standard USB or Bluetooth keyboard, it does not provide an efficient means for moving the computer cursor (although you can use "mouse keys" software).
How It Works
The Safe-laser System is simple from the user's perspective, but it is a sophisticated device. The large area laser-sensing surface was designed specifically to meet the needs of people with disabilities. It works in a broad range of lighting environments, from darkness to near direct sunlight.
The Safe-laser System uses a thin paper "vellum", common in the art and drafting industries, for defining key locations and functions. the user points at the vellum and the laser is detected. The user (or an aide) uses our Safe-laser Keyboard programming software to define the graphics and the function for each key. Graphics can be simple letters or complex images. Functions consist of defining what is:
- Printed on the on-screen display (letters, words, or combination of words)
- Sent to computers, tablets, or phones via USB or Bluetooth
- Spoken from two rear-facing speakers
- Activated by the built-in universal remote control
The time that the laser must target a cell in order to activate it (the "dwell" time) is also configurable. Keys can also be defined as a system function like clearing the display or adjusting the volume of the speaker.
The safe-laser pointer has a docking station on the back of the laser-keyboard. Charging the laser-keyboard simultaneously charges the laser pointer. The laser keyboard also has a standard VESA mounting plate on the back, making it easy to mount for use in bed or with in a wheelchair.
Since 1995, InvoTek has focused on pursuing new ways for people with disabilities to access computers, environmental controls, and augmentative communication devices. InvoTek’s mission is to empower people with severe disabilities through the development of accessible technology. The people they serve are integral to the research and design process. They are the teachers and the critics, ensuring that the products meet their needs.
