Digital Technology: Applications and Considerations

E-Voting

Considerations

• Voter ID
• Candidate ID and Voter ID
• Representing information in text format
• Secure section for additional fields
• Providing a set number of options to reduce data input errors

Data Collection Methods

Questionnaires

Advantages: Less labor-intensive than interviews.

Disadvantages: Poorly designed questions (e.g., overuse or lack of closed questions) can lead to misunderstandings.

Interviews

Advantages: Provide more detailed information than questionnaires; allow for face-to-face interaction.

Disadvantages: Time-consuming; require skilled interviewers.

Technical Aspects

• MAC address and IP address management
• Voice recognition software: Converts analog speech to digital sound, then to text using a sound database. Matches words to determine validity and display on screen.

Cloud Computing: Advantages

• Easy maintenance
• Accessibility from multiple locations
• Duplicate/alternative versions for redundancy
• Multi-location backup for data security

Data Compression and Image Quality

Image Resolution: Images intended solely for on-screen viewing do not require the same high resolution as those intended for printing.

Lossy Compression: While lossy compression reduces file size, it can lead to quality loss. In cases where preserving the original quality is crucial, lossless compression or no compression should be used.

Privacy vs. Anonymity

Privacy: Concerns knowing who a person is but not knowing what they are doing. It involves keeping activities entirely private or limited to a specific group.

Anonymity: Concerns knowing what a person may be doing without being able to identify them.

Portable Digital Devices in Healthcare

Applications

• Monitoring vital signs: Heart rate/pulse and blood pressure
• Tracking location: GPS receivers utilize satellite data to track movement, such as a runner's route.
