Discussions and perspectives Users stressed position for arm, hand. Better: lifted like phone or resting arm. Learning time & previous knowledge. Device sensitivity, best area of performance Software sound feedback & keyboard layout could be improved Task real text entry input: text dictation, creation. 20.9.2018 NIT 2003: finger manipulation device

NIT 2003: finger manipulation device Applications mobile phone embedded, hybrid input device on mouse or on keyboard or stand alone. New Computer Mouse developed to prevent Mouse Arm Syndrome. Johan ULLMAN, Fredrik WARTENBERG, Pia ULLMAN, Nils KANGAS by using Ullman mouse like a pen, muscles in the forearm and upper arm are at rest and the user's hand and forearm are in a more natural position, rather than being twisted around horizontally, as they are when a mouse is used [5,6] http://www.ullman.se/ullmanmouse/mouse/ 20.9.2018 NIT 2003: finger manipulation device

NIT 2003: finger manipulation device Conclusions The results of the project can be used for development and assessment of input devices and new features in user interfaces. 20.9.2018 NIT 2003: finger manipulation device
