Abstract - Many elderly people struggle to manage their daily health routines, remember medications, or seek help duringemergencies,especiallywhenlivingalone. Sahara-Bot solves these issues by acting as a voice-enabled personal assistant. It uses Optical Character Recognition (OCR) to identify medicines, send timely reminders, schedule appointments, and send instant alerts. The system is simple, interactive, and cost-effective, helping seniors remain independent and safe. Sahara-Bot shows how specialised digitalsystemscanmakeelderlycareeasierandmorereliable bycombiningvoicetechnology,anAIchatbot,areminder,and automation, providing a sense of relief to the elders, their families and caretakers

The rising shift in the ageing population is posing several challenges in healthcare management. According to the WorldHealthOrganisation(WHO),thepopulationaged60 yearsandolderisexpectedtogofrom12%to22%thatis nearly double between 2015 and 2050. This ageing population faces numerous difficulties in their daily lives, such as maintaining health, independence and safety, especially when living alone or with limited support. This populationfacessomechallenges,suchasmanagingmultiple medications, remembering complex health routines and prescriptions and seeking immediate help when in an emergency.
Many existing applications and systems fail to meet the specificneedsofolderadultsdespitethevastdevelopment in digital healthcare technologies Traditional health management systems revolve around visual interfaces, complex navigation menus, and manual data entry, which maynotbeverysuitableformiddle-agedoragedindividuals withage-relatedimpairments,suchasweakvision,hearing loss,cognitivedeclineorphysicallimitations.Additionally, existing general virtual assistants, although capable of performing basic voice commands, somehow lack the contextualunderstandingrequiredforelderlycare
Therefore, this problem needs a solution, which is an intelligent,user-friendlysystemmadespecificallyforelderly users Sahara-Bot integrates multiple technologies like OpticalCharacterRecognition(OCR)forreadingmedication

The growing elderly population has led to increased researchinassistivetechnologiesthatpromoteindependent living and healthcare management. Over the past decade, several digital health systems have been developed to address age-related challenges, including memory loss, medicationmanagement,andmobilitylimitations.However, mostofthesesystemsfocusonmedicalmonitoringrather

than on user-centred accessibility, leaving a gap in technology designed specifically for elderly users. Early studiesonassistivetechnologiesemphasisedsensor-based systems for remote health monitoring. For example, wearable devices and smart home sensors were used to collecthealthparameterssuchasheartrate,movement,and sleep patterns. While effective in data collection, these solutionsoftenrequiretechnicalsetupandmaintenance, whichcanbeoverwhelmingforolderusers(Rodríguezetal., 2022). Additionally, the cost of such systems limits their accessibilityinlowandmiddle-incomeregions.
Several studies have also explored the use of Optical Character Recognition (OCR) in healthcare. OCR enables automatic reading of printed text, such as medical prescriptions or labels, which is particularly useful for elderlyuserswithpooreyesight.Forexample,Google’sML Kit and Tesseract OCR have been applied in various healthcare applications to extract and digitise medical informationaccurately.Despitethis,fewsystemsintegrate OCRdirectlyintoavoice-controlledecosystemdesignedfor seniors.
From this review, it is clear that while individual technologies like voice assistants, OCR, and reminder systems have been well-studied, there remains a lack of integration among them within a single, easy-to-use platform. The Sahara-Bot project addresses this gap by combining these technologies into a single mobile application focused on simplicity, affordability, and accessibility.Itcreatesaninteractivecompanionthatassists elderlyindividualsinmanagingtheirhealthproactivelyand independently.
The proposed system architecture is a Health platform integratinga Streamlit frontend,a Flask RESTfulAPI,anda MongoDB NoSQL database.
