Eye-pass 1.0

What is Eye-pass

Eye-pass uses invisible laser beams to measure distances up to 10 m. It turns each distance into a sound, helping you detect objects, people, stairs, and surfaces around you. The included bone-conduction headphones transmit sound without occluding the ears, so that ambient sounds are never missed.

In the box

• Eye-pass device
• Bone-conduction headphones
• USB-C cable
• Long neck strap
• QR code card for the online manual
• Printed instruction leaflet

How to use

• Before first use, charge the device fully using the provided USB-C cable (max 1 A). A red light near the USB port turns on while charging and off when complete. Charging typically takes 1–2 hours depending on the charger. The device can be used while charging, e.g. connected to a power bank (minimum 0.7 A).
• The measuring sensors face forward. Secure the wrist strap around your wrist before use.
• Alternatively, you can replace the pre-attached wrist strap with the neck strap.
• Connect the headphones to the jack plug at the back of the device.
• Place the headphones arch behind your head, pads in front of your ears; not on top. Move them slightly until the sound is clear.
• Turn the device on with the switch on the right side (slide towards the front). The device immediately starts producing sound based on the measured distance. If no headphones are connected, sound plays through the built-in speakers.
• Adjust volume with the wheel on the left side.
• When the measured distance is less than 120 cm, the device vibrates. The closer the object, the stronger the vibration.
• Press and hold the top button to activate Zoom mode, which narrows the sound range for finer detection at close distances. Vibration is disabled in Zoom mode.
• Use the device for a few days, first in familiar environments, to get familiar with the sound feedback and start recognizing shapes and patterns in the environment.
• When the battery is almost empty, an acoustic warning and short vibration are triggered.

Suggestions and use examples

• Eye-pass produces stereo sound from two LiDAR sensors. An object passing from one side to the other produces a sound that travels from one ear to the other.
• Some objects produce distinctive patterns. For example:
  • grids
  • stairs
• Eye-pass can be used, among other things, to:
  • locate an open door
  • locate low and high obstacles
  • find a free seat
  • locate the WC in an unknown restroom from a distance
  • sense the orientation of supermarket aisles
  • other use cases depend on the user’s habits and will be identified using the device during the day
• The zoom function is particularly helpful with smaller objects. For example, it can be used to locate a bottle on a table.

Safety

• Eye-pass aids environment recognition; it is not a mobility device. Always use it in safe environments and do not replace your white cane while moving.
• The device takes point measurements. Move it around actively; large nearby objects may go undetected if the device is held still.
• Some surfaces may not reflect the laser beam and go undetected; glass is one example, with detection varying across types.
• Water may not be detected reliably. Do not rely on Eye-pass near pools or other bodies of water.
• The sensors use eye-safe lasers. However, avoid staring directly into the beams for extended periods.
• Prolonged exposure to high volume may cause hearing damage. The device is intended for short usage sessions only.
• The device is designed for the included headphones. If you use other headphones, set the volume to minimum before connecting them; other models may produce excessive volume and damage your hearing.
• If using the neck strap, do not use it near hazards that could catch or pull it. If the lanyard is adjustable, never tighten it around the neck. Keep away from children.
• Contains a Li-ion battery: do not leave in a hot environment, do not attempt to open, do not dispose of in fire.
• If the device is damaged, stop using it and contact support.

Maintenance

• Turn the device off before cleaning. The case can be wiped with a soft, lightly damp cloth or a disinfectant wipe.
• Keep the front lenses clean for best performance. Use a soft dry cloth to clean them.
• Keep away from water and liquids. Store in a cool, dry place when not in use.
