Let's Use Haptics!
Keywords:Haptic interfaces, Sensors, User interfaces, Virtual reality
The concept and the use of haptic devices need to be disseminated and they should become familiar among young people. At present haptics are used in many everyday tasks in different fields. Additionally, their use in interaction with virtual reality applications simulating real systems sense of touch will increase the usersâ?? realism and immersion and, consequently, they will contribute to improve the intrinsic knowledge to the simulationsâ?? goals. However, haptics are associated with expensive equipment and usually they offer several degrees of freedom. The objective of this work is to make their cost not much more expensive than a â??specialâ? mouse by offering a low cost solution with just one degree of freedom (1DOF) useful in many simple cases. Additionally, it is also an objective of this work the development of simple virtual reality systems requiring interactions only requiring one degree of freedom. A low cost, single-axis force-feedback haptic device of 1 degree of freedom has been developed. For evaluating the interest of this prototype a â??Spring Constantâ? application was built and used as a demonstrator. The complete system - the haptic interacting with the â??Spring Constantâ? - will be described in the present work.
