Customer Feedback

“Thank You so much!”

“I can’t tell you how much this has improved my life.”

“Bless You !!”

“This has given me hope.”

“My son took to the LaZee Mouse like a duck to water. He’s tried the others, but nothing worked well.”

“Thank you”

“The eeZee Mouse has opened up a whole new world for me.”

“Best System I’ve ever used. 
Always smooth whether fast or with slow precise movements”

Tilt Sensor

What is a Tilt Sensor?
&
What is Body sensor computer control?

 

     A bubble level is a basic tilt sensor.  An electronic tilt sensor functions like the bubble level and outputs data describing its position. As with any level, bumping or moving it will cause the bubble to move. 

Bubble Level

The  most important thing when using a tilt sensor is to
 attach the sensor firmly
to the activating surface (body part) and to
support the cable
so that it doesn’t interfere with sensor travel during operation.

 Tilt Sensors are found in:

  • Car Airbag sensors
  • Camera focusing
  • Wii controllers

 Tilt Sensors are found in:

  • LaZee Mouse units
  • eeZee  BODY Sensors
Body Sensor

     Tilt sensors are used by tilting them!  As a sensor is tilted, its output changes for each position it is moved to. A typical sensor may have 2000 different outputs.

     In a Wii game the controllers are “tilted” to play  the game.  In LaZee Tek products they are tilted to directly control the computer cursor.

     LaZee Tek products use 2 tilt sensors mounted perpendicular to each other. One sensor is used to control up/down movements while the other left/right.

     LaZee Mouse units have the sensors inside the case, while eeZee Mouse units have relocated the two sensors into the tiny Body Sensor.

     Both models operate as a joystick in space!

Dual Tilt sensors

 

   Characteristics of a Tilt Sensor:

  1. Extremely accurate!  The tilt sensor is reported to be the most reliable and accurate positioning system ever used in Assistive Technology computer controls. 
     
  2. The sensor detects all movements.  When properly installed, it can provide the user smooth cursor control with very fine resolution. 
     
  3. When improperly installed, a loose sensor can rock back and forth, wobble around, or move unintentionally. These movements could translate into undesired and misunderstood cursor activity.   When this characteristic is understood, proper mounting can be provided giving precise reliable performance.

     Providing the sensor a stable mounting position
is the key to successful operation.

  

OK, so how do I use this Body sensor to operate a computer?

  1. Place the sensor where it is to be worn, anywhere from head to toe! (within 60 degrees of level)
  2. Calibrate the sensor simply by pressing the “Home” button.
  3. Tilt the sensor slightly to begin moving the cursor slowly!  Tilting a little farther will speed it up.  Returning to home will stop moving.

     Your body has been transformed into a joystick with fully proportional cursor movement.  Cursor speed is proportional to the degree of tilt.

   Tilting        Moves Cursor
     Left            Left
     Right         Right
     Forward       Down
     Back          Up

     eeZee units have a Range of Motion (ROM) control the user can adjust to set the desired degree of tilt needed to reach full speed. A small ROM will require very little movement, while a large ROM requires more. Moving beyond this maximum will not affect cursor speed.

   Installing the sensor so that it is mounted firmly and stable is the
key to successful operation.
