Abstract
A wheelchair can include a control system that is configured to operate the wheelchair using an input device and a scanning device. The scanning device may be programmed to have a multi-tiered scan sequence. A first tier of the multi-tiered scan sequence may include at least a first operation option that is configured to operate a specific function of the wheelchair. A second tier of the multi-tiered scan sequence may include at least a second operation option that is also configured to operate a specific function of the wheelchair. The second operation option is generally selected less frequently than the first operation option included in the first tier.
