Case Study on Mouse Geometry to Enhance the Human Performance and Comfort During Online Survey Task

Abstract

The feedback plays a very important role in forecasting and successful execution of any industries. To save the time, easiness, fastness, quickness, most of the firm prefer to do online survey and also to promote the online surveying. There is a revolutionary increase of online usage. Today industrial feedback, survey, the entrance exam, online teaching, tutorial became a very familiar and easy trend for education. The online preparation for the entrance exam, tutorial and even the competitive exam are also preferred to be done through on line by just clicking the option of the multiple questions. In India most of the exams like Gate, Bank Job, Railway recruitment board etc are taking the online paper for job. Hence the frequency of mouse use increases. So it becomes very important to use an ergonomically designed computer mouse so that the performance increases as well as the safety of human increases. The software programs for word processing, spreadsheet, database and graphics operations may require computer mouse use for up to two-thirds of the time. The duration of mouse use and the forces applied to the mouse by a computer operator are two risk factors that may play an important role in the development of musculoskeletal disorders [1]. The objective of the study was to compare the effect of different designs of computer mouse on human performance. The flexion of the index finger, wrist extension and ulnar deviation was measured and compared by the use of biometric software and instrument. Statistical analyses for the data was done, the results, showed that the flexion angle and time duration to complete the task were dependent on the mouse and hand geometries of subject. The wrist injuries were mostly due to awkward posture and improper support. This extension of wrist can be reduced by using the keypad and mouse of best fitted geometry.
