Perangkat penunjuk memberikan bantuan dalam pengoperasian komputer. Perancangan perangkat mouse menggunakan lengan atas bertujuan untuk membantu penyandang tunadaksa untuk mengoperasikan komputer dengan lebih baik. Prototipe mouse perlu dilengkapi dengan fasilitas klik untuk menggantikan tombol klik mouse. Penelitian ini bertujuan untuk meneliti mana yang lebih baik penggunaan tombol klik di kaki kiri (prototipe A) atau kaki kanan (prototipe B). Sedangkan penggerak kursor sendiri menggunakan sensor di lengan atas. Penelitian dilakukan dengan menggunakan metode penilaian Fitts’ Law yang diterapkan oleh ISO 9241-411, pengujian dilakukan dengan 9 subjek non tunadaksa. Subjek melakukan pengujian dengan menggunakan perangkat lunak untuk melakukan pengujian multi-directional tapping sesuai standar ISO 9241-411. Pengisian kuesioner untuk memperoleh data kualitatif dilakukan setelah pengujian menggunakan perangkat lunak. Penyaringan data dilakukan untuk menghilangkan galat, dan ketika data telah siap, dilakukan pengujian statistik untuk menguji performa, tingkat kenyamanan, dan tingkat kelelahan. Pengujian performa dilakukan menggunakan data Time of Movement dan Throughput, sedangkan untuk pengujian tingkat kenyamanan menggunakan Assessment of Comfort, dan untuk pengujian tingkat kelelahan menggunakan Assessment of Fatigue.

Continuous Theta Burst Stimulation

AbstractThe neural mechanisms underlying the effects of continuous Theta-Burst Stimulation (cTBS) in humans are poorly understood. Animal studies can clarify the effects of cTBS on individual neurons, but behavioral evidence is necessary to demonstrate the validity of the animal model. We investigated the behavioral effect of cTBS applied over parietal cortex in rhesus monkeys performing a visually-guided grasping task with two differently sized objects, which required either a power grip or a pad-to-side grip. We used Fitts’ law, predicting shorter grasping times (GT) for large compared to small objects, to investigate cTBS effects on two different grip types. cTBS induced long-lasting object-specific and dose-dependent changes in GT that remained present for up to two hours. High-intensity cTBS increased GTs for a power grip, but shortened GTs for a pad-to-side grip. Thus, high-intensity stimulation strongly reduced the natural GT difference between objects (i.e. the Fitts’ law effect). In contrast, low-intensity cTBS induced the opposite effects on GT. Modifying the coil orientation from the standard 45-degree to a 30-degree angle induced opposite cTBS effects on GT. These findings represent behavioral evidence for the validity of the nonhuman primate model to study the neural underpinnings of non-invasive brain stimulation.
