SPACE MOUSE

OUTLINE: Introduction Principle Space mouse Types Specifications Features Working Visual space mouse Applications Advantages Future scope Conclusion

Introduction: Space mouse is developed by the DLR institute of robotics and mechatronics. DLR- Deutsches Zenturum far Luft-und Raumfahrt. First prototype applications of DLR control was showed from 1982-1985. The high sales price of about $8,000 per unit

Principle: The basic principle behind its construction is mechatronics engineering and the multisensory concept. Measuring system is drift-free and not subject to aging effects. Movements were measured by electromagnetic or ultrasonic. The measuring arrangement in the inner ring is composed of the LED, a slit and perpendicular to the slit on the opposite side of the ring a linear PSD.

SPACE MOUSE: Space Mouse is a professional 3D controller manipulating objects in a 3D environment. It has different modes of operation in which it can also be used as a two-dimensional mouse. Groundbreaking interface. Enables the user to intuitively zoom, pan and rotate models.

TYPES: Two types of space mouse Space mouse classic Space mouse plus

Specifications: PRODUCT Space Mouse Classic Space Mouse Plus SENSITIVITY adjustable  BUTTONS 9, programmable 11, plus Quick tip programmable INTERFACE RS-232C RS-232C or USB CONNECTOR D-sub 9 pin D-sub 9 pin or USB WEIGHT Weight 1.46 lb (0.66 kg) 1.5 lb (0.68 kg) DIMENSIONS (LxWxH) 6.50" x 4.41" x 1.57" (165 x 112 x 40mm) 7.40" x  4.72" x 1.73" (188 x 120 x 44mm)  WARRANTY 36 Months

Features: Ease of use of manipulating objects in 3D applications. Calibration free sensor technology for high precision and unique reliability. Nine programmable buttons to customize users preference for motion control. Fingertip operation for maximum precision and performance. Adjust sensitivity and motion control to the users preference. Small form factor frees up the desk space. Natural hand position (resting on table) eliminates fatigue.

Visual space mouse: Visual space mouse can be divided into two main parts Robot control Image processing

Applications: Works in graphical applications. Object manipulation in 3D applications.

Advantages: Drawing times is reduced by 20%-30% . Works without an additional power supply. Adapted for a wide range of tasks including mechanical design, real time video animation and visual simulation.

Future scope: ROTEX is the only well known virtual environment. Machine instruction allowance. To develop virtual environment using space mouse.

Conclusion: we believe there is no other man- machine interface technology comparable to Magellan in its simplicity and yet high precision. It is used for 3D manipulations in 6 doff, but at the same time may function as a conventional 2D mouse.
