The Coulomb failure plane method of design is compared with a sliding block design method for fabric sheet-reinforced retaining walls. The quantities of anchorage material required by the two design methods are calculated. Bench model tests are used to compare the surcharge loads resisted by given quantities of anchorage material distributed over a range of geometries between those indicated by these two design methods.

Abstract This article summarizes the design and evaluation of a new augmentative and alternative communication (AAC) interface strategy for people with complex communication needs and severe physical limitations. This strategy combines typing, gesture recognition, and word prediction to input text into AAC software using touchscreen or head movement tracking access methods. Eight individuals with movement limitations due to spinal cord injury, amyotrophic lateral sclerosis, polio, and Guillain Barre syndrome participated in the evaluation of the prototype technology using a head-tracking device. Fourteen typical individuals participated in the evaluation of the prototype using a touchscreen.
