 note = {The objective of this study is to improve usability of backpack type power dusters, taking the concept of a universal design into account. Also, the background of this study and the former studies on backpack type power dusters and universal design are reviewed.
We first evaluated the usability of four units of commercialized backpack type power dusters, employing the testing subjects of 16 people aged in their 20s to 60s. We asked the subjects to operate the machines, following the steps of “engine starting up”, ”engine stopping”, ”spraying of agricultural chemicals”, and ”adjusting a metering shutter”. An interview thereafter was carried out for the subjects regarding usability or requirements to be improved. We obtained many requests for the improvement of machine from them. The requests were reviewed from the standpoints of a universal design concept.
As a result, we put our focuses on an improvement of labeling considering sensory and cognitive abilities of the users, and an improvement of control device, taking the users’ physical constitutions and abilities into account.
An improvement of labeling was carried out, while paying attention to cognitive abilities of the users. The labeling and control device on commercialized machines were investigated from the standpoint of user-friendliness, especially for an improvement in indicating information such as “an-easy-place-to-find”, “an-ease-of-understanding”. Three prototypes were made attached with the improved labeling, and these prototypes, together with the conventional machine, were evaluated in a subjective way. The subjects were 15 people aged in their 40s to 60s. We asked the subjects to operate the machines, following a simulated procedure such as starting up. After that, investigations of usability or requirement for improvement were carried out. The feedback differed depending on the skill of the operator. The best evaluated prototype was the one labeled with a procedure guidance and indicators of each control., 背負型動力散布機の取扱性に関し、市販機４ 台を供試して、「エンジン始動」、「薬剤散布」、「エンジン停止」及び「シャッタ調節」の模擬操作を20～ 60歳代の被験者男女16 名に行ってもらい、各操作に対する改良要望を得た。これらを分析し、ユニバーサルデザ  イン（ＵＤ） 視点及び使用者の認知能力に配慮して操作表示の分かりやすさを反映した操作モデルを３ 台試作した。40～ 60歳代の被験者男女15名で主観評価を実施した結果、操作系統別に色分けしてレバーパネルラベル等を改良したモデルが好評価であった。},
