An investigation of the effects of touchpad location within a notebook computer
This study evaluated effects of the location of a notebook computer's integrated touchpad, complimenting previous work in the area of desktop mouse location effects. Most often integrated touchpads are located in the computer's wrist rest, and centered on the keyboard. This study characterized effects of this bottom center location and four alternatives (top center, top right, right side, and bottom right) upon upper extremity posture, discomfort, preference, and performance. Touchpad location was found to significantly impact each of those measures.
Spinalistips
Many people with spinal cord injury have themselves become experts on their disability. They have been imaginative and inventive when it comes to the tools and tricks for facilitating everyday life.
Dorothee Riedel and Elisabeth Lagerkrans are occupational therapists and have for many years worked with people with spinal cord injury. They have learned much from their “patients” and a large part of their professional knowledge is based on this. They know that the best ideas and tips for everyday life are those that people with spinal cord injury themselves come up with.
Design Guidelines for Wearable Pointing Devices
This paper presents design guidelines and recommendations for developing cursor manipulation interaction devices to be employed in a wearable context. The work presented in this paper is the culmination three usability studies designed to understand commercially available pointing (cursor manipulation) devices suitable for use in a wearable context. The set of guidelines and recommendations presented are grounded on experimental and qualitative evidence derived from three usability studies and are intended to be used in order to inform the design of future wearable input devices.
