Title:
キーパッドエルゴノミクス
Document Type and Number:
Japanese Patent JP2008513906
Kind Code:
A
Abstract:
Systems and methodologies are provided for improving dynamics of striking a key on a keypad during operation thereof, by shifting contours (e.g., slope of a key's surface plane) on surface of a key, based on location of that key on the keypad, and a manner (e.g., the finger used) the key is being stroked. Accordingly, the subject invention can employ varying surface contours to optimize contact between a user's finger and the key at any point depending on predetermined geometric locus for the movement of a user's hand and/or fingers when employing the keypad. A wave key and a pillowed key arrangement are disclosed according to exemplary aspects of the invention. Moreover, a raised protrusion ("ski jump feature") can be provided around edges of keypad to enhance grip capabilities for the key pad and/or the host device.
