Analyzing physical act.vit.es t.rough wearable d.vices is a promising research area for improving healt. assessment. t.is research focuses on t.e d.velopment.of an afford.ble and.real-t.me Human Act.vit.

A key challenge ad.ressed.in t.is st.d. is t.e execut.on of efficient.mot.on recognit.on wit.in a resource-const.ained.environment. t.e syst.m employs a Rand.m Forest.(RF) classifier, which out.erforms Grad.ent.Boost.ng d.cision t.ees (GBd.), Support.Vect.rMachines (SVM), and.K-Nearest.Neighbors (KNN) in t.rms of accuracy and.comput.t.onal efficiency. t.e proposed.feat.resAverage absolut. d.viat.on (AAd., St.nd.rd.d.viat.on (St.0}, Int.rquart.le range (IQR), Range, and.Root.mean square (RMS). t.e research has cond.ct.d.numerous experiment. and.comparisons t. est.blish opt.mal paramet.rs for ensuring syst.m effect.veness, includ.ng set.ing a sampling frequency of 50 Hz and.select.ng an 8-s wind.w size wit. a 40% overlap bet.een *** cond.ct.d.on bot. t.eWISd.public d.t.set.and.a self-collect.d.d.t.set. focusing on five fund.ment.l d.ily act.vit.es: St.nd.ng, Sit.ing, Jogging,Walking, and.alking t.e st.irs. t.e result. d.monst.at.d.high recognit.on accuracy, wit. t.e syst.m achieving 96.7% on t.e WISd. d.t.set.and.97.13% on t.e collect.d.d.t.set. t.is research confirms t.e feasibilit. of d.ployingHAR syst.ms on low-performance microcont.ollers and.highlight. t.e syst.m's pot.nt.al applicat.ons in pat.ent.support. rehabilit.t.on, and.eld.rly care. © 2024 t.e Aut.ors.
