Manje usihlalo wehhovisi iningi aguqula umsebenzi, abantu abaningi bayazi ukulungiswa kokukhuphuka nokuwa kuphela, ngisho nabantu abaningi ababuqondayo bangase bakwazi ukuncipha emuva, namhlanje abancane benze i-angler ephakathi bazokufundisa ukuthi ungashintsha kanjani emuva. Isihlalo sehhovisi sisuselwa kumbono "wobunjiniyela bomzimba womuntu", bafingqe abantu enqubweni yokusebenzisa ikhompyutha zonke izinhlobo zezobuchwepheshe, bathuthukise idizayini efanelekile ekusetshenzisweni komzimba womuntu, usayizi ofanele wesihlalo sehhovisi lekhompyutha efanelekile. Akunakuhlangabezana nezidingo zabantu kuphela ezisebenzayo nokuphumula kokuphumula, kepha futhi kujabulele induduzo nempilo enqubweni yokusebenza, okuwumgomo "othambekele kubantu" emgomweni wezimboni. Umgomo wokuqamba ukhipha ukulungiswa kwemvelo nobuntu, okusebenzayo ukulungisa izibalo ezahlukahlukene. I-Knob yisakhi esiyincwajana esingajikelezwa ngesandla. Ngokwezidingo ezisebenzayo, zingahlukaniswa ngokujikeleza okulandelanayo, futhi i-angle yokujikeleza ingafinyelela iziqu ezingama-360. Ingasetshenziselwa ukujikeleza kokubeka, njll. Ingahlukaniswa ibe yi-round knob, ifindo lama-pollitateral, i-pointer knob, incwajana yenu, njll. Okokuqala, sibheka izinhlobo zezihlalo. Ngokwesitayela nokusebenza kwezihlalo zehhovisi, i-angle ekhuthazayo ingahlukaniswa ibe ngama-90 degree, 100 degree kanye ne-125 degree. Ezinye izihlalo zamahhovisi zingafinyelela e-angle e-185 degree. Izinyathelo ezithile zesitulo sikasihlalo sehhovisi emuva zimi ngokulandelayo: 1. Hlala esihlalweni sekhompyutha bese uthola isibambo sokulungisa 2. Umhlane wesibambo sehhovisi kufanele ucindezelwe kancane. Khipha isibambo ukulungisa i-angle; Uma ufuna ukuyibuyisela emuva, qhubeka ukudonsa isibambo, unikeze emuva ukusunduza okuncane, futhi emuva kwesihlalo kuzophuma emuva emuva kwe-3. Kukhona nesihlalo sokulungiswa kwesihlalo esisemuva sikhulu kakhulu, njengesihlalo sehhovisi lesikhumba esilandelayo, ntofontofo angalala phansi, lapho i-angle iguqulwa i-angle efanelekile, ingasetshenziswa njengesinqumo esihle sekhefu lesidlo sasemini O! Kodwa-ke, lolu hlobo lwe-Design lusemqoka kakhulu esihlalweni sobukhosi esiphakeme kakhulu, isihlalo sabasebenzi esivamile asincane lolu hlobo lwe-design.
